═══ 2. Impos/2 functions ═══

Functions in Impos/2 are available via two distinct menus: 

o The main menu 

  situated in the top region of the Impos/2 window provides functions that 
  apply to several windows at the same time, as well as functions that are 
  independent from other windows. 

o The context menu 

  provides functions that apply only to a single window. The context menu is 
  activated by clicking on the symbol in the upper left corner of window. 

With regard to that, the image window context menu provides the most extensive 
functions. 


═══ 2.1. The palette window ═══

The palette window displays the colors used in an image; it also provides the 
ability to select specific colors. In black-and-white and grayscale images the 
possible gray values are shown (in black-and-white images two); in palette 
images the colors of the used palette are shown and in true color images a 
sequence of the rainbow colors is shown (red-yellow-green-blue-course). 

The field beneath the color squares displays the color values for red, green 
and blue when crossing with the mouse. 
Like the tool window the palette window is arranged horizontal in the middle of 
Impos/2 work domain and can be changed in size and position. 

In its presentation it adjusts to the momentarily active image window. In 
capture windows it shows an empty content. 
The color squares on the left part show the foreground and background color. By 
clicking the mouse in the palette domain the foreground color can be selected 
with the left, the background color with the right mouse button. 
A double click on the color squares or on a palette field enables the changing 
of color in the normal color circle (also see Settings of background color in 
the OS/2 manual). 

Amongst other functions, the system menu of the palette window enables the 
loading and storing of palettes in the OS/2 palette format (as used in the OS/2 
icon editor).

on the tool the actual condition of the image is saved. This can be used in a 
significant manner by turning a tool on and off very quickly, in order to be 
able to switch back to an intermediate level, e.g. when drawing free hand. 


═══ 3.3.5.1. Help for tool Brush ═══

With help of the brush the image can be colored. When pressing the left mouse 
key the foreground color selected from the palette is applied. When pressing 
the right mouse key the background color is applied. The mouse can be dragged 
over the image when keeping the key pressed. Several crossing over the same 
part increases the color application. If the mouse is moved too fast, not all 
crossed image parts are covered. 

The brush can only be used for images with 256 grayscales or true color images. 


═══ 3.3.5.2. Help for tool Pen ═══

The pen works similar to the brush, but covers all image parts even when 
pulling the mouse very fast. This happens by connecting the dots of the mouse 
moving by a straight line. The right and left mouse key can be used for the 
foreground or background color with the pen, too. 

In black-and-white images, 16 grayscale images or palettes images 100 % 
congruance with hard border course is used. 


═══ 3.3.5.3. Help for tool Line ═══

The line connects two dots with the foreground or background color. For this 
the first dot is clicked onto with left (foreground) or right (background) 
mouse key and the mouse is lead to the end dot with pressed key. A rubber band 
shows the position of the line. When letting go of the mouse key the two dots 
are connected and the line is presented in the strength of the given tool size 
with corresponding border course and the corner dots are presented in the given 
form 

Before letting go of the left mouse key the function can be interrupted with 
the not used mouse key or the Esc-key. 

Tip:  If the image is larger than the sector presented on the screen, the mouse 
pointer can be moved over the image border with pressed mouse key;the image 
then scrolls automatically in the desired direction. 

In black-and-white images, 16 grayscale images or palettes images 100 % 
congruance with hard border course is used. 


═══ 3.3.5.4. Help for tool Airbrush ═══

The airbrush sprays the color onto the image and covers stronger and stronger 
when remaining longer on an image part. The spraying speed is defined. quantity 
can be changed with suitable selection of congruance. Here, too, foreground and 
background color can be applied with left or right mouse key. 

The airbrush can only be used in images with 256 grayscales or in true color 
images. 


═══ 3.3.5.5. Help for tool Floodfill ═══

Floodfilling fills contiguous areas of similar color with the current fore- or 
background color, providing the means to even fill bizarre shapes with one 
specific color. The settings for this tool allow changing the color tolerance 
and thus the area effectively filled. A low tolerance limits the filling 
process to areas with minor differences in brightness, whereas a high tolerance 
increases the size of the filled area. 

The left mouse button fills using the foreground color, the right mouse button 
similarly with the background color. 


═══ 3.3.5.6. Help for tool Razor blade ═══

The razor blade enables the local undoing of the last action, which means e.g. 
a drawn line can be partly removed. Congruance and border course define the 
size of removal of the image. The razor blade refers to the level of option 
"Undo". 

Tip:  The razor blade can e.g. also be used to show a flipped image again which 
original is sort of hidden. 

In black-and-white, 16 grayscale images or palette images 100 % congruance with 
hard border course is used. 


═══ 3.3.5.7. Help for tool Eraser ═══

The eraser can be used to delete parts of image. The left mouse key deletes in 
white color, the right mouse key in black color. If these colors are not 
available in a palette image, the darkest resp. the brightest color of the 
palette is selected. 

The eraser is comparable to a pen with fixed color arrangement. 

In black-and-white images, 16-grayscale images or in palette images 100 % 
congruance with hard border course is used. 


═══ 3.3.5.8. Help for tool Finger to wipe ═══

The finger enables the wiping of colors to desharpen the borders after putting 
two images together or after coloring with 100 % congruance. The finger takes 
up the color when clicking with the mouse and wipes it on those image parts 
which are crossed with pressed mouse key. The congruance accords to the 
pressure when wiping. 

The right mouse key has no effect. 

The finger can only be used in images with 256 grayscales or in true color 
images. 


═══ 3.3.5.9. Help for tool Brightness ═══

This tool enables the local increasing and decreasing of the image brightness. 
The crossing of an image part with pressed left mouse key brightens the area, 
the right mouse key darkens accordingly. The value of congruance defines the 
volume of brightening or darkening. The border course is used for shading of 
brightness change. 

Crossing the image part several times has no strengthening effect. 

The brightness can only be changed in images with 256 grayscales or in true 
color images. 


═══ 3.3.5.10. Help for tool Contrast ═══

This tool enables the local strengthening or weakening of the image constrast. 
The crossing of an image part with the pressed left mouse key strengthens the 
contrast, the right mouse key weakens accordingly. The value of congruance 
defines the volume of contrast change. The border course is used for shading of 
the contrast change. 

Das mehrmalige Ъberfahren der Bildstelle hat dabei keine verstДrkende Wirkung. 

Der Kontrast kann nur bei Bildern mit 256 Graustufen oder Echtfarbenbildern 
verДndert werden. 


═══ 3.3.5.11. Help for tool Sharpen/Smooth ═══

This tool allows a localized sharpening or smoothing of the image. When the 
tool is applied (by moving the mouse across an area) while keeping left mouse 
button depressed, the area is sharpened; doing the same with the right mouse 
button depressed will smooth the area. Both of these procedures correspond to 
their filter equivalents which can be applied to the entire image. 


═══ 3.3.5.12. Help for tool Color exchange ═══

The color exchange enables the local exchange of foreground and background 
colour. In all image parts that are crossed with pressed mouse key the 
foreground color is replaced by the background color and vice versa. If the 
crossed image area has neither foreground nor background color there are no 
changes. This tool is especially suitable in palette images or black-and-white 
images. In grayscale or true color images the color exchange is generally 
applicable in drawings, which show uniformed color areas. 

The right mouse key has no effect. 

Border course and congruance have no influence when exchanging color. 


═══ 3.3.5.13. Help for tool Clone ═══

Cross-fading (also Graphic tampon) enables the aimed copy of single image areas 
to another position/place. When selecting this tool a crosshair appears beneath 
the mouse pointer, that moves with the mouse. When clicking with the right 
mouse key this crosshair is fixed to the image position/place which shall be 
copied (Original area) and begins to blink. Without pressing a mouse key you 
can move on to the desired end/aimed area. When pressing the left mouse key the 
end/aimed area is covered with the image area which is beneath the crosshair. 
Several crossings increase the grade of covering. The original area can be 
repositioned with the right mouse key at any time. 

This tool can only be applied in images with 256 grayscales or in true color 
images. 


═══ 3.3.5.14. Help for tool Text ═══

The Text tool is used to position an arbitrary text within an image; the text 
then becomes an integral part of the image. When the mouse button is pressed a 
dialog is displayed which allows entering the text as well as selecting the 
desired font, orientation and size. 

The left mouse button will use the foreground, the right mouse button the 
background color for inclusion of the text. 

Once the dialog is confirmed, a frame is the size of the text is displayed 
within the image window; this frame can be repositioned as needed by clicking 
it with the left mouse button and dragging it to the desired position. A 
double-click with the left mouse button or hitting the enter key will conclude 
placement of the text. The right mouse button or the Esc key will abort this 
procedure. 


═══ 3.3.5.15. Help for tool Zoom ═══

The magnifying glass enables the stepwise enlargening or reduction of the image 
presentation. This presentation does not change the image data themselves, 
opposite to option Resize image in submenu Image functions, which recalculates 
the image data themselvesen. 

When clicking with the left mouse key the presentation size is doubled, which 
means a pixel appears twice the size on the screen, whereby the mouse position 
becomes the new center of the presented sector. Correspondingly the right mouse 
key reduces the image by the half. In this way enlargenings up to factor 16 and 
reductions to a quarter can be reached. These settings can also selected via 
keyboard View 


═══ 3.3.5.16. Help for tool Hand ═══

The Hand enables the moving of the image with the mouse, if the whole image 
cannot be presented. The image is touched by pressing the left mouse key and 
then moves with the movings of the mouse accordingly. The same effect can be 
reached by using the arrow keys of the keyboard. 

The right mouse key has no effect. 

The hand does not change the image data. 


═══ 3.3.5.17. Help for tool Pipette ═══

The pipette enable the selection of color of a pixel from the image. If the 
tool pipette is aktive, the color beneath the mouse pointer in the left field 
is shown in the info line. The output for color images happens in the basic 
colors red-green-blue in the value area of 0 to 255. In palette images the 
color index (color position within the palette beginning with 0) is added in 
brackets. 

In grayscale images both numerical (0 to 255) and percentual (0 % to 100 %) 
gray value are given in brackets. 

The foreground color is set with the left mouse key, the background color with 
the right mouse key and is shown directly by opened palette window. 

The pipette does not change the image data. 


═══ 3.3.5.18. Help for tool Rectangular Selection ═══

The rectangular selection enables the marking of a rectangular image sector for 
the options in submenu Edit: A rubber band with eight so-called hotspots is 
displayed. The selection frame can be changed in size by clicking onto a 
hotspot (left mouse key) and pulling it. By clicking in the selection frame it 
can be moved. When clicking outside of the selections frame the old selection 
frame is deleted; a new selection frame can be pulled by pressing the mouse key 

The selection frame is only shown in the active window; a selection that might 
exist in a non-active image window is invisible. 

If the image cannot be displayed in full size, the image moves out of the image 
window by pulling the mouse when moving as well as enlargening the selection 
frame in the desired direction. 

When pressing the mouse key the position of the left bottom corner as well as 
the size of the selection frame is shown in the info line. 

The right mouse key or the Esc-key stops the moving or the changing of size. 

The selection does not change the image content. 

Warning:  The selected area encloses the selection frame itself, which means 
the pixels beneath the rubber band belong to the selection. 


═══ 3.3.5.19. Help for tool Freehand Selection ═══

tbd. 


═══ 3.3.5.20. Help for tool measure distance and angle ═══

When switching on the tool Measure distance/angle a horizontal rubber band with 
two hotspots as end points appears in the middle of the visual image area. A 
hotspot is round, it represents the middle point of a virtual circle. The 
second hotspot is square, it represents the outer point of this circle. When 
moving one of the two hotspots the radius and angle of the circle line are 
shown in the right field of the info line. The angle specification refers to 
the mathematical rotation angle (anticlockwise) Winkelangabe bezieht sich dabei 
auf den mathematischen Drehwinkel referred to the horizontal (0°). The 
specification of the radius can happen according to the unit setting in the 
info line in pixels, cm or inch, whereas cm and inch specifications refer to 
the actual resolution of the image. 

Tip:  If the palette window or the tool bar is activated, the rubber band can 
be invisible under one of these windows. 

The right mouse key has no effect. 

This tool does not change the image content. 


═══ 3.3.6. Help for option Undo ═══

This option undoes the last done action or editing within an image. For example 
if a color image was converted into a grayscale image, the original color image 
can be reproduced in this way. The menu text is adjusted according to the last 
done action, which means in above example the text changes for "Undo: 
Grayscales". 

The undo action itself can also be revised. In the named example you can switch 
from color image to grayscale image and back. 


═══ 3.3.7. Help for image window Edit ═══

The functions of the submenu Edit image area refer to selection areas of the 
image. The selection area can be defined with the tools Rectangular Selection 
or Freehand Selection: 

o Cut 
o Copy 
o Paste 
o Fill 
o Flip horizontal 
o Flip vertical 
o Image copy 

If no selection frame is defined, the functions refer to the whole image. 

Apart from this under this submenu contains the options that work with the 
clipboard. The clipboard enables direct exchange of data with other 
applications. Impos/2 only supports the bitmap format in the clipboard. 


═══ 3.3.7.1. Help for option Cut ═══

When cutting the image area is transferred into the clipboard and then filled 
with the actual background color. This option corresponds to the performance of 
copying and filling. 


═══ 3.3.7.2. Help for option Copy ═══

When copying the image area is put in the clipboard as bitmap and can be taken 
over from there from other applications, like e.g. a PM or Windows Text 
processing. 

Note:  In black-and-white images inversion can occur when exchanging two 
applications because not all applications consider the definition of both 
colors. If necessary the image area with option image copy has to be made into 
an own image window, in order to invert it into the clipboard before 
transferring. 


═══ 3.3.7.3. Help for option Paste ═══

Paste enables the taking-over of a bitmap from the clipboard into an existing 
image. If there is no bitmap in the clipboard, this option is not selectable. 

Note:  This option differs from the option Capture from clipboard of the main 
menu. A new image window from the bitmap of the clipboard is made there. 

After this option was selected, the top left half of the actual image is 
covered with the bitmap from the clipboard. The bitmap that is to be inserted 
is displayed with a rubber band. The bitmap can be clicked onto as often as 
desired with the left mouse key and can be moved. A double click with the left 
mouse key or with the Enter key inserts the bitmap into the image. If the 
bitmap juts out of the image, it is cut accordingly. 

With the right mouse key or the key Esc the process is finished. 

Warning:  If the bitmap was pushed so far out of the image that it is no longer 
visual and thus can no longer be captured with the mouse, Impos/2 stops the 
process. 


═══ 3.3.7.4. Help for option Fill ═══

This option fills the image area with the actual set background color. It can 
typically be used to e.g. remove a writing or other not wanted image contents. 


═══ 3.3.7.5. Help for option Flip horizontal ═══

When flipping horizontal the image sector is flipped on the vertical middle 
axis of the image area. This option is e.g. suitable for making mirror-writing. 


═══ 3.3.7.6. Help for option Flip vertical ═══

When flipping vertical the image sector is flipped on the horizontal middle 
axis of the image area. Then the image is upside down. 

A rotation thru 180° corresponds to a horizontal and vertical flipping. 


═══ 3.3.7.7. Help for option Image copy ═══

An image copy produces a new image window of the selected areas. This happens 
directly without clipboard, opposite to the possibility of putting the image in 
the clipboard with copy and producing a new image window over the option 
Capture, from clipboard 


═══ 3.3.8. Help for option Print ═══

This option starts the dialog Print image, which enables the output of the 
image on a black-and-white or color printer. 


═══ 4. Capture with scanners ═══

Impos/2 supports a variety of scanners. The main differences in operation stem 
from the type of the scanner. The following chapters give further tips: 

The context menu 
Hand scanner 
Flatbed scanner 


═══ 4.1. Hand scanner ═══

The hand scanner is manually moved across the document during the scanning 
process. For the quality of the result an even and steady movement of the 
device is important. Otherwise drop-outs and distortions may appear within the 
scanned image. With the option Scan the scanning process is started. If you 
have set a warmup time (for hand scanners with color support) a process 
indicator is displayed at the bottom of the scanning window. Press the start 
button on the scanner and guide the device slowly and even across the document. 
The warmup phase can be aborted with the Esc button. 

The scanning process ends after 

o the maximum length of the scan area, 
o Timeout is reached or 
o when the button Esc is pressed. 

After scanning the image data can be turned into an image with the Capture 
option. 


═══ 4.2. Flatbed scanner ═══

The scan window displays the maximum scanning area supported by the scanner. 
The selection frame within this region defines the area of the document to be 
scanned; it can be repositioned and resized as needed. 

Selection  of the Preview option will cause the application to do a low 
resolution scan and display the result within the scan window. The final scan 
is limited to the area indicated by the selection frame. Adjust this area by 
positioning the frame with the mouse and resize it by using the hotspots. 


═══ 4.3. Scanner modules ═══

The following index entries give an overview of scanners supported by Impos/2, 
summarized in groups. 


═══ 4.4. Help for HP-ScanJet ═══

With the HP-ScanJet support of Impos/2 image copies can be captured 
electronically. 
An image sector can be definded, the contrast or brightness can be changed or 
the image can be edited by using another method to adjust the image to the 
purpose of use like keeping of files or the reproduction of photographies. 

The following scanners are supported: 

o HP ScanJet 
o HP ScanJet Plus 
o HP ScanJet IIp 
o HP ScanJet IIc 
o HP ScanJet IIcx 


═══ 4.4.1. Help for scanner Information ═══

In the info display window information on the installed scanners is displayed. 

Following information is shown: 

o The scanner model as well as the corresponding internal model number. 
o The maximum scan area, which can be shown either in centimeter, inch or 
  pixel. 
o The minimum and maximum resolution, which the scanner supports. 
o If an automatic document feeder (ADF) can be installed. 
o How many grayscales and colors the scanner supports. 


═══ 4.4.2. Help for scanner settings ═══

The scanner settings determine the values for the next scan process. The 
settings are stored permanently and are valid for all following scan processes. 


═══ 4.4.3. Help for image type black-and-white ═══

When scanning with the setting black-and-white, the images are scanned as line 
drawings, which means the scanner does not distinguish any brightness shades of 
the copy. (comparable to the setting of a maximum contrast). 

This image type should always be used when the copy exists of black and white 
areas like e.g. a printed piece of paper or a piece of paper typed by machine. 

This setting requires the least space when storing the image. 


═══ 4.4.4. Help for image type bitmap ═══

When scanning with the setting bitmap brightness shades of the image are copied 
by fine bitmaps, which are far away from one another by bright areas and for 
dark areas are very close to one another. 

This image type should be used when an image copy (e.g. a photo) with low need 
of storage space should be captured and the quality demands are not very high. 


═══ 4.4.5. Help for image type grayscales ═══

When scanning with the setting Grayscales brightness shades of the image are 
captured from the scanner as different gray values, which means every raster 
dot of the copy is arranged to a gray value. 
The number of grayscales can be selected: 

o 16 grayscales are a good result for computer displays. 
o 256 grayscales have about the quality of a black-and-white TV (they need 
  twice the storage space of an image with 16 grayscales). 

This image type should be used when high quality demands exist and the high 
need of storage has to be taken into account. 

Because of the high need of space which is eight times higher than for a 
black-and-white image or a bitmap, this setting should not be used for complete 
DIN-A4-pages. 


═══ 4.4.6. Help for image type color image ═══

When scanning with the setting color image an image is scanned, which needs 24 
Bit for every captured dot for presentation. This is also called TRUE COLOR 
Quality. But the scanning of color images needs lots of memory. 

A DIN-A4 page scanned with a resolution of 300 dpi, needs about 24MB space of 
storage. 


═══ 4.4.7. Help for 16/256 grayscales ═══

Two shades are available: 

o 16 grayscales 

o 256 grayscales 

In an image that is scanned with 16 grayscales, 4 Bits are needed for 
presentation for every captured pixel. Therefore this image uses less storage 
space and can be printed faster. With this image type the high image quality of 
the image type with 256 grayscales is not reached. 

In an image that is scanned with 256 grayscales, 8 Bits are needed for 
presentation for every captured dot. With this image type the best possible 
image quality is reached but more storage space is necessary. 


═══ 4.4.8. Help for halftoning ═══

Four halftonings are available: 

o rough 
o middle 
o fine
o vertical line 

In rough halftoning the image is smoothened and gray tones are mixed. This 
image type can be recommended for images with large uniform color areas and 
relative few details, e.g. faces. 

In middle halftoning lots of details are captured, and a fine structure 
results. This raster is recommended if more details have to be captured but 
smoothing and mixture of the gray tones should be kept. 

In fine raster more details are captured, but the image structure is only 
average. This image type is recommended for images with many details, e.g. 
buildings, landscapes or mechanical objects. 

In vertical lines horizontal arranged details are stressed and an image 
structure is reached. It is recommended for photos with lots of horizontal 
lines. 


═══ 4.4.9. Help for resolution ═══

The number of scanned dots per inch (dpi) is called resolution. If the number 
of dots per inch increases, the exactness of capture and thus the quality of 
the scanned image increases, too. 

Five standard resolutions are available: 

o 75 dots per inch 
o 100 dots per inch 
o 150 dots per inch 
o 200 dots per inch 
o 300 dots per inch 

Besides the given standard values the resolution can be set as desired with the 
spinbutton. Minimum and maximum resolution are scanner dependant and can be 
looked at in the scanner information window. 

Please be aware that for higher resolutions more storage space is needed. An 
image with 300 dpi uses four times the storage space of an image scanned with 
150 dpi. 


═══ 4.4.10. Help for brightness/contrast ═══

In higher brightness settings the images are scanned brighter, in lower 
settings the images get darker. The adjustable area for brightness is between 
-128 and +128, the standard value is 0. 

The difference between the light and dark areas of an image is set with the 
contrast. The adjustable area for contrast is between -128 and +128, the 
standard value is 0. 

Example : In a black-and-white display with the highest contrast setting all 
dots are either presented black or white. With lowest contrast all dots are 
presented gray. 

Impos/2 allows setting the brightness and contrast also for an already scanned 
image. Yet better results are reached when optimum values are used already when 
capturing. 
It is recommended to do a few test scans in order to find the optimum values. 
This is the only way to develop a feeling for the optimum image capture. 


═══ 4.4.11. Help for Error by initializing of scanner support ═══

The support module that administrates the connection to  your scanner, cannot 
be loaded. The capturing via scanner is not possible. 

Please check if your scanner is connected properly and if the scanner is 
switched on and the correct device driver is installed. 


═══ 4.4.12. Help for Scanner does not answer ═══

The contact to the scanner is interrupted. 

Please check if your scanner is connected properly and if the scanner is 
switched on and the right device driver is installed. 

If the scanner is addressed via a DOS device driver, the scanner support 
program should be active. If this is not the case, Impos/2 must be restarted in 
order to activate the scanner support program again. 


═══ 4.4.13. Help for unvalid reply/answer from scanner ═══

Unvalid data were read from the scanner. 

Please check if your scanner is connected properly and if the scanner is 
switched on and the right device driver with the valid parameter is installed.

o The version numbers of the scanner adapter (SPI) and of the device driver. 
o The author of the device driver and the type of the connected scanner. 
o The maximum scan width supported by the scanner. 
o Which I/O port address is occupied. The I/O port adress serves the 
  communication of the application and the scanner-interface adapter. 
o Which I/O adress space is used. This info field goes back to the DOS driver 
  specification. 
o Which interrupt request (IRQ) is used. 
o Which channel number (DMA) the scanner uses for the transfer of data. 


═══ 4.5.2. Help for scanner Settings ═══

The scanner settings determine the values for the next scan process. The 
settings are stored permanently and are valid for all subsequent scanning 
processes. 


═══ 4.5.3. Help for Scan mode ═══

Here the scan mode which determines the color format of the image that is to be 
scanned is shown. With some hand scanners several scan modes per switch 
position can be selected from the listbox. 


═══ 4.5.4. Help for Refresh ═══

Scan mode and resolution are re-read and the display is updated. The resolution 
can be shown either in dpi (dots per inch) or lpc (lines per centimeter) . 


═══ 4.5.5. Help for Timeout ═══

This setting determines how long the interval is before the scan process is 
automatically interrupted, if the hand scanner is not moved. This is a safety 
measure to avoid accidental overheating of the lamp in the scanner. 


═══ 4.5.6. Help for Scan Width ═══

Here the width of the document that is to be scanned is set. The maximum values 
are scanner dependent. 


═══ 4.5.7. Help for Scan Length ═══

values are scanner dependent. 


═══ 4.5.8. Help for scanner Warmup ═══

For optimal scanning results, the lamps of some scanners (primarily color 
scanners) should be warmed up prior to use, whereas the initial warmup period 
should be longer than subsequent ones. 


═══ 4.5.9. Help for Inital Scanner Warmup ═══

For optimal scanning results, the lamps of some scanners (primarily color 
scanners) should be warmed up prior to use. Here the interval for this initial 
warmup period is set. 


═══ 4.5.10. Help for Subsequent Scanner Warmup ═══

For optimal scanning results, the lamps of some scanners (primarily color 
scanners) should be warmed up prior to use. Here the interval for subsequent 
warmup periods is set. 


═══ 4.5.11. Help for Real-Time Display ═══

If real-time display is selected, the image data received from the scanner is 
immediately diplayed in the scanning window as it arrives. If the scanner is 
set to color- and/or high resolution mode, this may cause large chunks of the 
image to be displayed in short amounts of time. This causes a very high load on 
the system, which in turn may affect the final result. Therefore it is 
recommended to turn off the real-time display in these cases. 


═══ 4.5.12. Help for Scroll Image ═══

Once the length of the scanned image exceeds the height of the scanning window, 
the result of the scanning process can no longer be monitored. This option 
avoids this problem by automatically scrolling the image when bottom of the 
scanning window is reached. 


═══ 4.5.13. Help for Scanning region too large ═══

The set scanning region is too large, i.e. there is not enough memory available 
to edit the data to be scanned. 

If necessary reduce the scan length or select a lower resolution. 


═══ 4.5.14. Help for Scan mode does not match scanner switch position ═══

The selected scan mode in thescanner Settings window does not match the scan 
mode that is set on the scanner. 

Please re-open the Scanner Settings window and select a valid scan mode. 


═══ 4.5.15. Help for Internal scanner error ═══

support) a process indicator is displayed at the bottom of the scanning window. 
Press the start button on the scanner and guide the device slowly and even 
across the document. The warmup phase can be aborted with the Esc button. 

The scanning process ends after 

o the maximum length of the scan area, 
o Timeout is reached or 
o when the button Esc is pressed. 

Flatbed scanner: 

The Scan option starts the scanning process. The image is captured according to 
size and position of the selection frame and is available as new image within 
the Impos/2 working area right after scanning. The scanning process can be 
stopped with the Esc key. 


═══ 4.7.3. Help for menu option Capture ═══

With the Capture option, the scanned image is converted into a new image window 
once the scanning process is complete. This menu option is only available for 
hand scanners and is only selectable if an scanned image is available in the 
scan window. 


═══ 4.8. Scan error ═══

The following chapter describes the possible general error messages which can 
occur when scanning. 


═══ 4.8.1. Help for Scanner error ═══

═══ 5. Capturing from video camera ═══

The current version Impos/2 supports the video-overlay-adapters manufactured by 
CPS (in part compatible with Creative Labs). 
Upon opening the capture window the analog image provided by the video camera 
is displayed within the window and can then be captured into a digitized form. 

The following chapters give further information: 

The context menu 
Settings 


═══ 5.1. Help for the video-adapter context menu ═══

The context menu of the video-overlay-adapter offers various individual 
functions as well as groups of functions, which in turn are divided into 
further submenus: 

o Open 
o Help 
o Video source 
o Freeze 
o Capture 
o View 
o Window 
o Close 

If an item is unavailable at some point, its menu selection is deactivated and 
is diplayed with its text greyed. 


═══ 5.1.1. Help for menu option Video source ═══

The video source can be identified as one of the channels supported by the 
hardware. In case of the TV Movie Blaster adapter, the image by the TV tuner is 
provided on video channel 1. 


═══ 5.1.2. Help for menu option Freeze ═══

When freezing, the image is held in the analog storage. 

Tip:  Capturing an image is easier when the image is frozen first, since it 
allows for finer control before the image is digitized. 


═══ 5.1.3. Help for menu option Capture ═══

The capturing of images is supported in grayscale or True Color format. If 
necessary, other formats can be attained by converting the digitized image 
within its image window. 
When capturing, the currently selected view affects the capturing process. If 
Fit to window 
During the capturing process, the image is frozen. 

Note:  The controls for brightness, contrast, color hue and saturation 
available via the Settings option have no effect on the captured image; they 
only control the display of the live video image and are not used by the 
digitizing hardware. Therefore it is recommended to already optimize the image 
at the source (camera). 


═══ 5.1.4. Help for menu option View ═══

Two viewing options are supported: 

o Fit to window 

  fits the entire video image, distorted if necessary, into the capture window. 

o Original size 

  always displays the undistorted image; the viewable section of the image can 
  be adjusted by moving the scroll bars. 


═══ 5.2. Help for video adapter Settings ═══

The settings of the video adapter generally correspond to the settings 
described in the manual for the Windows* application provided with the 
video-overlay-adapter. 

o Video Color settings: 

  The color settings only affect the presentation of the video image on the 
  display. These settings are not considered when an image is captured. 

o Video Ausrichtung: 

  The Video-Ausrichtung has to be set according to the installation of Impos/2 
  and is used whenever Impos/2 is invoked. For a further discussion of this 
  parameter please consult the documentation provided with the adapter. 


═══ 6. Help for Photo CD Overview ═══

The individual images available on the Photo CD are displayed as slides within 
the overview window. A selection frame can then be moved to the image of 
interest either with the mouse or by using the cursor keys. A double click or 
the enter key then opens this image. 

When first invoked after installation, the Kodak Photo CD overview displays a 
setting dialog requesting the drive identifier of the CD-ROM drive. 

The following chapters give further information: 

The context menu 
Settings 
Photo CD Info 


═══ 6.1. Help for Photo CD Settings ═══

In addition to the CD-ROM drive identifier, the size and color format to be 
used when loading images from the Photo CD can be selected in this dialog. This 
setting affects both modes of opening an image, i.e. when a slide is selected 
in the Photo CD overview as well as when an image file (PCD) is loaded by 
specifying a filename. 

Note:  PCD files contain 5 image sizes; an additional two smaller image formats 
are available and can be selected for the overview, so that altogether a 
variety of (horizontal) sizes from 48 to 3072 pixels are possible. 

The images can be loaded as palette images (8-8-4-palette) or as true color 
images. An image in the highest resolution (2048 x 3072 pixels) requires 6 
Megabytes of main memory as palette image (actually twice that for displaying 
it). The same image as true color image would require a total of 36(!) 
Megabytes of main memory. Therefore it is not possible to load images in their 
highest resolution as true color images. 

Warning:  The loading of higher resolutions can take several minutes. The 
standard resolution (512 x 768) requires about 15 sec. on an average computer 
with an i486 microprocessor. 


═══ 6.2. Help file for Photo CD info ═══

The information on a Photo CD contain: 

o The version number of the method that was used when capturing the data. 
o The serial number of the Photo CD, that was given when first capturing. 
o The date of the setting, which means when first writing on the CD. 
o The date of the last change, which means when last writing on the CD. 
o The number of images that are stored on the CD. 
o The number of sessions, which means how often the CD was written to. Every 
  writing process (which normally transfers several photos onto the CD) 
  represents an additional session. 


═══ 6.3. Help for the Kodak Photo CD context menu ═══

The context menu of the Kodak Photo CD offers the various individual functions 
as well as groups of functions, which in turn are divided into submenus: 

o Open 
o Help 
o Refresh 
o View 
o Window 
o Close 

If an item is unavailable at some point, its menu selection is deactivated and 
is diplayed with its text greyed. 


═══ 6.3.1. Help for menu option Refresh ═══

The option Refresh restarts the reading of the Photo CD overview, e.g. after 
changing the CD in the drive. Images are read at about 1 image per second. 
While the overview is rebuilt, you can continue your work within Impos/2. The 
key Esc stops the reading process, which means no further slides are loaded. 


═══ 7. Dialogs ═══

Dialogs are used to fulfill certain actions, which need further specifications 
and are usually controlled via pushbuttons. 

The pushbutton Cancel is almost always available, which stops the action that 
has just begun without furter effects, whereas the pushbutton OK generally 
starts an action. 

Following index entries show an overview of all dialogs: 


═══ 7.1. Help for dialog Product information ═══

═══ 7.2. Help for dialog image list ═══

The window list allows raising a specific image or capture window to the 
foreground. This list is only displayed if more than nine document windows are 
open so that the list in the action bar under Window is no longer sufficient to 
show all images.

    Using Impos/2 


═══ 7.3. Help for dialog Open image file ═══

In this dialog you can select and open an image file. 

In the entry field Image file the name of the file that is to be opened can be 
entered directly. If this name is not fully qualified the active values in the 
list boxes for disk drive and directory are taken as basis. 
If one of the symbols '*' or '?' is used in an image file name and the 
Enter-key or the pushbutton OK is pressed, all files that suit this filter 
condition appear in the file list. 

The list of file formats has two functions: When selecting a format all files 
with the standard extension of these formats (e.g. BMP for bitmap) are shown in 
the file list. If, when pressing OK a certain format is selected, Impos/2 tries 
to open this file only in this format. Otherwise Impos/2 automatically 
determines the file format upon loading (by reading the beginning of the file). 

The field Filter allows to specify a general valid OS/2 file filter. Here 
Impos/2 defines <all files>. 

In the list disk drive you can define from which disk drive you want to read. 
When changing the disk drive the valid current directory is changed. 

The list Directory allows changing of the directory from which you want to 
read. The directories are symbolized as small files that open when they are 
activated by mouse or keys. Changing of directory displays a new file list. 
The file that is to be opened can be selected directly from the file list, 
without manual entry in the field image file. 

If the pushbutton OK is pressed and the name in field Image file  is complete, 
the file is read.  If the name still contains '*'- or '?'-characters, only the 
file list is updated correspondingly. 

Tip:  Impos/2 remembers the last loaded file name and shows this name in the 
file list that was already selected. When calling the opening dialog again the 
next file can be loaded via double click on the file below. 


═══ 7.4. Help for dialog Create New Image ═══

For creating a new image an image window with a white image is produced, which 
can then be further edited. 

Besides the image type (e.g. black-and-white or True Colors) the size and the 
width of the image must be defined. When giving an entry in cm or inch the last 
resolution set in this dialog is used as basis. When changing a value in one of 
the fields cm, inch or pixel the specification in the other scales are updated 
correspondingly. 

The overview shows the correct scale size of the image referring to the 
display. Contrary to the dialog Resize image the scale is calculated in pixels. 

Via pushbutton resolution another dialog is opened, in which the dot density 
can be defined. In general the dialog corresponds to the dialog Define 
resolution for an already existing image. 

Note:  If a palette image is created, the OS/2 standard palette is used for 16 
colors; 256 colors uses an 8-8-4-palette.

    Change image size 


═══ 7.5. Help for dialog Save as ═══

When saving an image, name, file format, compression and in some image formats 
further options (Pushbutton Options) can be selected. The dialog Save as is 
automatically called, if no name, file format and/or compression have been 
given when calling the option Save 

If the image is already named (because it was loaded from hard disk or 
diskette), this name is set as a default in the field Image file ; if the 
picture has no name (because it was newly created), the last name used is 
displayed as default and can be changed. 

In newly created images file format and compression are undefined - the 
pushbutton OK can only be selected when both attributes have been defined. 

The lists Filter, Disk drive, File and directory allow the selection of the 
desired directory, without having to name the path in field Image file An 
already existing file is overwritten if a name has been selected within the 
list File and thus has been copied into field Image file 

If you try to overwrite an already existing file a warning appears. 

Warning:  If an image was loaded and converted into a color format which is no 
longer supported by the original file format, the fields File format and 
Compression have no entry; they have to be defined once again. 


═══ 7.6. Help for dialog Set resolution ═══

The resolution of an image defines the size of a pixel or, to be exact, the 
number of pixels per measuring unit when printing. It can be given in dpi (Dots 
per Inch) or in the metric system lpc (Lines per cm). The horizontal and 
vertical image resolution need not be identical. 

Changing the image resolution does not change the image data itself; rather it 
is saved as an extra attribute of the image. 

The option Horizontal/vertical equal sets the horizontal values equal when the 
vertical value is changed (and vice versa). 

When entering a dpi-value the indication of the corresponding lpc-value is 
updated (and vice versa). 

The list Special resolutions enables the simple setting of standardized 
resolutions (300, 150, 75 dpi) or the resolutions from display or the default 
printer. 

The image size corresponds to the set resolutions referring to the pixel size 
(the unit Pixel does not change the values, because the pixel size of the image 
is not influenced by the changing of resolution). 

The Overview shows the new image size as dark hatched area referring to the old 
image size. If the new image size exceeds the old size, the contours of the 
previous image area can be seen in correct proportion within the hatched area. 

Note:  Not all file formats support saving the resolution. If the resolution 
cannot be determined when loading an image, the display resolution is used. 


═══ 7.7. Help for dialog Select printer ═══

This dialog allows selection of one of the configured printers in your system. 

Choose the desired printer from the drop-down list at the top of the window. 

Within the field Printer parameters 

o Page size, 
o the resolution and 
o the number of available colors 

of the printer are now shown. These parameters are not changeable, they only 
quote printer specific attributes. 

The page size can be indicated in pixel, cm or inch. 

The resolution can be shown in dpi (Dots per Inch) or lpc (Lines per 
centimeter) 

The field Postscript indicates whether the selected printer supports Postscript 
as a data stream. 

Click on the pushbutton Settings, in order to select special printer attributes 
in a further dialog, such as paper size, orientation when printing or paper 
cartridge. The possible settings are printer-dependent. 


═══ 7.8. Help for dialog Palette ═══

The palette window displays the colors used in an image and allows making 
selections thereof. In black-and-white and grayscale images the possible 
grayscales (two in black-and-white images) are shown; in palette images the 
colors of the used palette are indicated and in true color images a clipping of 
the rainbow colours (red-yellow-green-blue-course) is shown. 

In the output field in the bottom left corner of the dialog the RGB-value of 
the colour square under the mouse pointer is shown. 

The palette window, like the tools window, can be changed in size and position. 

The indicated palette corresponds to the currently active image window. In 
capture windows the palette window is empty. 

The color squares on the left show the foreground and background color. When 
clicking the mouse in the palette domain, the foreground color can be selected 
with the left, the background color with the right button. 

A double click on the color squares or on a palette field allows changing the 
color in the standard color circle (see OS/2 manual, System settings, Color 
palette). 

The System menu of the palette window allows amongst other things the loading 
and saving of palettes in OS/2 palette format, as used by OS/2 Icon editor.

═══ 7.9. Help for dialog Save palette as ═══

In this dialog you can save an edited palette for later re-use. 

When saving, a file name must be entered in the entry field Palette; The 
default extension of the file name is *.PAL. 


═══ 7.10. Help for dialog Load palette ═══

Here, you have the possibility to apply an existing palette to the current 
image. 

Put the name of the desired image in the Open-dialog or select it via disk 
drive list, directory list and file list. 

The palette is applied directly to the image, that means the palette entries 
are overwritten which can lead to strange colors. 

It is not possible to load a 256-color palette onto a 16-colour image or vice 
versa. 


═══ 7.11. Help for dialog Image info ═══

When calling Image info a dialog with detailed information abaut the active 
image is displayed: 

o Type 

  In file the memory format like bitmap (BMP) or Graphics Interchange Format 
  (GIF) of the image is given. If the image was newly created, the memory 
  format cannot be given (Indication: - not defined -). 

  In Compression the compression method of the file that is read is given. 
  This, too, is not defined for new images. 

  The Format shows if it is a black-and-white image, a grayscale image, a 
  palette image or a true color image. 

  In Colors the number of colors or grayscales is indicated; the bits per pixel 
  are displayed as well. 

  The size of the uncompressed image data corresponds to the actual memory 
  requirements for the image, (without extra information), without 
  consideration of the compression. 

o Dimension 

  The image size gives the size of the image in pixel, cm or inch referring to 
  the image resolution. 

  The resolution can be displayed in dpi (Dots per Inch) as well as in the 
  metric specification lpc (Lines per Centimetre). 

  The unit settings made for image size and resolution are valid throughout 
  Impos/2, which means they are also used elsewhere. 


═══ 7.12. Help for dialog Rotate image ═══

Aside from the angles 90°, 180° and 270° available from the menu, an image can 
also be rotated through any other angle. A larger image is created and the 
borders are filled with the current background color. 

First define the Angle Then select one of the options 

o tilt onto side, 

o upside down or 

o any angle. 

Any angle can be specified in the range 1° to 359° The degree value always 
refers absolutely to the current image orientation even if the image has 
already been rotated. 

The arrow in the Overview visualizes the rotation and serves as estimation of 
the result. 

Note:  A rotation of 0° does not change the image; therefore the OK-pushbutton 
is deactivated. 


═══ 7.13. Help for dialog Print image ═══

In this dialog the printer is directly selectable from the drop-down list 
Printer, therefore setting of the printer via Printer setting from the main 
menu may be omitted. 

Print- and images size are displayed. The unit for the size display can be 
selected with a drop-down list. Possible choices are inch, cm and pixels. 

The Size adjustment defines the printed image size: 

o By image pixels 
  Each pixel of the image corresponds directly to a raster point of the 
  printer, i.e. the resolution of the image is set to the resolution of the 
  printer. 

o By image resolution 
  The image is printed according to its size defined by resolution. 

o Fill page 
  The image is resized to fill the entire printed page. The resizing is done 
  according to the unit defined for the resolution (since horizontal and 
  vertical image resolution can be different, resizing according to pixels 
  could lead to different result). 

If the checkbox Draw frame is switched on, the image is printed with a 
surrounding thin black frame. 

The horizontal and vertical orientation defines the desired position of the 
image on the printed page. If the image is larger than the printed page, it 
will be clipped during output. 

Note:  The overview shows the effects of the changes and reflects the correct 
size and position of the image in relation to the printed page. 

The pushbuttonSettings next to the printer name opens the printer specific 
setting dialog for defining the paper format, the raster resolution etc.. 

Some printers allow setting the Number of copies In this case the image is only 
converted once and printed several times. Printers that do not support this 
option convert the image several times. 

The pushbutton Options opens a dialog Print options, which defines conversion 
of the image to black-and-white before printing. 

For colour printers, select here whether the printout should be in color or in 
black-and-white. 

_________________________ 

    Define Printing options 


═══ 7.14. Help for dialog Printing options ═══

Before printing an image on a black-and-white printer a color image or a 
grayscale image has to be converted into a black-and-white image. 

Various methods of image conversion are available for this. On the left part 
the dialog allows selection of the method, on the right conversion parameters 
can be set: 

o Halftone 
  In halftone or dithering method the desired shades of gray values can be 
  selected. The shade rough simulates the gray levels by a small raster but 
  only few gray tones can be simulated. A fine shades enables the simulation of 
  lots of gray values, but it uses a rougher raster so that the resolution of 
  the image seems far less. 

o Diffusion 
  In Diffusion or default distribution the points are found out by continuance 
  of a default value across the image, in order to define whether a dot has to 
  shown in black or in white. 

  The diffusion method often makes patterns, especially with uniformed areas, 
  (Interference or MoirВ). 

o liminal value 
  In the liminal value method the brightness of pixel is the basis for deciding 
  whether it shall be reflected in black or white. The liminal value shows the 
  brightness in percentage from which a pixel shall be shown white.A small 
  liminal value produces a bright image, whereas a liminal value of 100 % 
  produces a black picture. 

o Postscript-Driver 
  The transformation of the image to black-and-white is done only be the 
  postscript-driver. Naturally this option is only selectable if a postscript 
  suitable printer was selected. 

It is possible with colour printers to make a black-and-white print via the 
selection field Transformation to black-and-white 


═══ 7.15. Help for dialog Transformation to black-and-white ═══

When transforming an image into black-and-white various methods of image 
conversion are available. 

The dialog enables the selection of the method on the left part,on the right 
adjustments of values can be done. 

o Halftone 
  In halftone- or grid method the desired gradation of grey scales can be 
  selected. The shading Rough simulates the grayscales by a small raster 
  whereby only few gray tones can be similated by raster dot.br A fine shading 
  enables the simulation of many grayscales, but uses a large raster for this, 
  so that resolution of the image seems lower. 

  In clustered dot ditherings the grayscales are closened by circular 
  collections of dots ,in dispersed dot ditherings by a checkered-like pattern. 

  The clustered dot ditheing is more suitable for printers (with comparably 
  high solution) , whereas the dispersed dot dithering is suitable for the 
  presentation on screen. 

o Diffusion 
  In diffusion or default distribution the dots are estimated by continuance of 
  a default value across the image, in order to if a dot has to be presented in 
  black or white. 

  The distribution of the default can happen in various methods, which were 
  named after their developers. 

  The Diffusion method tends, especially in uniformed areas, to make patterns 
  (Interference or MoirВ). The option random distribution in the grid enables 
  the interference of a random value in the found defaults, to avoid the making 
  of the patterns. In this method the preparation takes much more time, though. 

  The damping shows the amount of default to be distributed. 0% means an entire 
  default distribution, whereas 100% gets close to the liminal value method. 

o Threshold 
  In the threshold method a decision is made based of the brightness of a 
  pixel, whether it shall be reflected black or white.The liminal value shows 
  the brightness in percentage, from which on a dot is reflected white.  Thus a 
  small liminal value produces a bright image, whereas a liminal value of 100 % 
  makes a black image. 


═══ 7.16. Help for dialog Conversion into 256 colors ═══

When converting into 256 colors various methods of image preparation are 
available. Each method uses a newly produced colour palette, which defines the 
allocation of the colour values. Three palettes are available: 

o 8-8-4 
  An 8-8-4-palette consists of 8 red-, 8 green- and 4 blue shades and is thus 
  responsible for the low color resolution of the human eye in the blue domain. 

o 6-6-4 
  A 6-6-6-palette has 6 gradations for all elementary colours (40 places remain 
  unused). 

o Optimized Palette 
  Here the palette is determined according to frequency distribution of the 
  image at beginning; This way the colours of the source image can be reflected 
  best. 
  Optimized palettes can only be used in combination with diffusion. 

Besides the palette selection you can define the type of image preparation: 

o Diffusion 
  In diffusion or default distribution the dots are found via continuance of a 
  default value across the image,in order to define, which colour is used from 
  the available palette. 

o Rastern 
  In the grid method the approximation of colours which are not in the palettes 
  is reached by changing arrangement of similar colour dots, whereby the 
  originale colour tone can be simulated. 

o Copy 
  In Copy the palette is directly diverted from the existing format, which 
  means an image with e.g. 16 grey levels produces a palette with 16 colour 
  values which correspond to grey tones. The free palette places are occupied 
  in black (there are always 256 palette places available). In this case all 
  other options are not activated. In true colour images Copy cannot be 
  selected. 

  Copy enables e.g.to produce a palette image out of a grey level image, to 
  then emphasize individual grey channels in colour. 

The button Default adjusts significant values referring to the original image. 


═══ 7.17. Help for dialog Resize size ═══

When changing the image size the image data is newly calculated, on contrary to 
the changing of view. 

The adjustments enable the separate changing of height and width. If the option 
Keep height-width ratio is selected, the height is automatically adjusted when 
changing the width and vice versa,that means the change of size happens 
distortionless. 

The new size can be given either as a percentage referring to the original 
image size, or by indication of a new scale in cm or inch (referring to the 
actual image resolution) or by a new amount of pixels. The other defaults are 
adjusted accordingly. 

If the option Interpolate is selected, mean values are calculated for the 
inserted pixels when the image is enlarged; if e.g. a pixel needs to be 
inserted between a yellow and a red pixel while the image is enlarged, the 
inserted pixel is set to an orange color, whereas without interpolation the 
existing pixel would only be copied. 

Interpolate is only selectable for images with 256 grey level or True colours. 

The Overview shows the new image as a dark hatched area in relation to the 
original image size. 


═══ 7.18. Help for dialog Attributes ═══

The attributes refer to the tools Brush, Pen, Line, Airbrush, Undo (razor 
blade), Eraser, Finger, Brightness, Contrast, Sharpen/Smooth, Swap colors and 
Clone. 

The icon bar in the top part of the dialog allows for the selection of the 
tools' shape. 

Size displays the overall size of the tool in pixels. Only odd numbers (1, 3, 5 
..., 29, 31) are supported. 

Opaqueness indicates the degree of coverage for the applied color. An 
opaqueness of 1% e.g. equals a very transparent application of color, whereas 
an opaqueness of 100 % covers the underlying area completely. For the tools 
Sharpen/Smooth, Brightness and Contrast, this indicates the intensity of the 
filters used. 
The Opaqueness is only supported for images with 256 grayscales and true color 
images. For all other image types the opaqueness used is always 100%. 

Edge allows selecting the distribution of opaqueness within the tool shape. A 
hard edge means an equal degree of coverage within the tool, whereas a medium 
or smooth edge setting means an increasing transparency of the applied color 
towards the tools' border. 
Edge-dependent opaqueness is only supported for images with 256 grayscales and 
true color images. For all other image types the edge type used is always hard. 

The Overview displayed within the dialog reflects the distribution of 
opaqueness as grayscales, with white indicating the least (actually no), black 
the maximum degree of coverage. 

Attribute settings are saved by Impos/2, i.e. they are available even after 
terminating and restarting the application. Settings made apply to all images, 
meaning that a change of the attribute set in one image also affects the 
attribute settings for all others. 

Note:  Clicking a tool icon with the right mouse button is an alternate method 
of invoking the attribute panel for the selected tool. 


═══ 7.19. Help for dialog Floodfill attributes ═══

The Floodfill tool allows the selection of the color tolerance for each of the 
three base colors red, green and blue in order to delimit specific areas. 

A color tolerance of 0% will only recognize areas with exactly identical 
colors, whereas a tolerance of 100% will include all color graduation in the 
area to be filled. Due to the seperation into the base colors, the blue- and 
green values can e.g. be set to 100%, the red value to 10%, meaning that areas 
with a similar amount of red will be filled regardless of brightness. 

When used with 256 grayscale images the values given are converted to the 
corresponding gray values. 

These settings are only supported for images with 256 grayscales and true color 
images. For all other image types only areas of identical color will be filled. 
The values are saved by Impos/2, i.e. they are available even after terminating 
and restarting the application. Settings made apply to all images, meaning that 
a change of the attribute set in one image also affects the attribute settings 
for all others. 

Note:  Clicking the tool icon with the right mouse button is an alternate 
method of invoking this panel for the Floodfill tool. 


═══ 7.20. Help for dialog Brightness and contrast ═══

The option Brightness and Contrast in the image functions always changes the 
entire image, on contrary to the tools Brightness and Contrast 

With screen drivers with 256 colours (with palette-Manager) the drivers effect 
the image directly which means the button Preview is not selectable. With other 
screen drivers the result can only be indicated with preview. 
Yet, the changes themselves only become effective when ending with OK 
The calculation of the preview can take a few seconds in large images. 

Note:  The indication with Palette-Manager and the real result after 
confirmation with OK can differ slightly from one another. 
Brightness and Contrast cannot be used in black-and-images. 


═══ 7.21. Help for dialog Hue and saturation ═══

With the editing of color hue and color saturation the optical impression of 
the active image can be changed. These changes have less meaning by the 
re-editing of realistic images, but can produce needed effects in some cases: 

o In artificial images (e.g.fractals) the colors can be set completely new. 

o In pictures with dominating colours (like a green meadow) the colour tone can 
  be slightly moved, in order to get a richer green. 

A moving of the slider Colour tone turns all colour values through the set 
degree on the colour circle. The colour circle contains the colours red, green 
blue and all flowing shades of these colours, whereby the intensity of the 
colours increases from inside to outside. 

The changing of the values with the slider saturation increases and reduces the 
color intensities. 

The option Color hue- and saturationalways changes the entire image. 

In screen drivers with 256 Color tones (with palette-Manager) the controllers 
effect the image directly, which means the button Preview is not selectable. 
With other screen drivers the result of the changes can only be shown with the 
button Preview; the changes themselves are only effective when ending with OK 
The calculation of the preview can take a few seconds in big images. 

Note:  The indication with palette-Manager and the actual result after 
confirmation with OK can differ slightly from one another. 
Colour tone and saturation can only be used in colour images. 


═══ 7.22. Help for dialog Text attributes ═══

The Text attributes dialog provides a means for specifying the text (and its 
attributes) that is to be placed into the image. 

Font allows selection of the font family as well as the font attributes. All 
installed vector fonts are available; raster fonts (e.g. System Proportional) 
cannot be selected due to their limited scaleability. 

The Font size can be specified in Pixel (i.e. independant from the image size 
and -resolution) as well as typographical units like Point and Pica. In 
addition centimeter (cm) and inch are supported. In that case the size refers 
either to the screen resolution, i.e. the text is placed within the picture 
with the displayed size, or to the image resolution, meaning the font size is 
calculated according to the the image size which in turn is defined by the 
resolution. 

Orientation allows rotation of the text at any angle. 

If the dialog is confirmed, a frame the size of the text is displayed within 
the image window. This frame can be moved with the mouse by clicking it with 
the left mouse button and dragging it to the appropriate position. 
Double-clicking the left mouse button or hitting the Enter-key inserts the text 
into the image at the position indicated by the frame; pressing the right mouse 
button or the Esc key discard the frame. 


═══ 7.23. Image filter ═══

Filters allow global changes to an image. They can only be used on the entire 
image. A set selection frame is not considered. 

All image filter can only be used for images with 256 grey levels or true 
colours. 

The following index entries show an overview of all color filter: 


═══ 7.23.1. Filter Mosaic ═══

Mosaic puts individual pixels in blocks of same color or same gray value 
together and has and effect like used on TV when masking faces. 

The block size can be given in an area from 2 to 16 pixels. 


═══ 7.23.2. Clean Filter ═══

When cleaning 'dirt particles' can be removed from the image. Pixels that 
differ strongly in color or brightness from their surrounding are eliminated 
while being replaced by the average of this surrounding. 

The size of the considered surrounding is shown as block size with the values 3 
x 3, 5 x 5, 7 x 7 or 9 x 9. The threshold shows the allowed difference. A small 
threshold changes the image a lot, a high threshold correspondingly less. 
In large block sizes and small thresholds the image loses contrast. 


═══ 7.23.3. Edge detection filter ═══

Edge detection reduces the image to lines, which show strong contrasts or color 
changes. 

The orientation of the edges can be shown in horizontal, vertical or in both 
directions at the same time. 


═══ 7.23.4. Sharpen Filter ═══

When sharpening the image contours and details of the image are emphasized. 

A sharpening of 1% hardly changes the image, 100% equals maximum sharpening. 


═══ 7.23.5. Blur Filter ═══

When blurring the colors or gray tones of neighbouring pixels run into one 
another (average), an effect occurs similar to Smooth, which reduces the 
contrast at the same time. 

The filter size is given by the block size (for making average); allowed values 
are 3 x 3, 5 x 5, 7 x 7 und 9 x 9. 

_________________________ 

    Smooth 


═══ 7.23.6. Smooth Filter ═══

Smooth is an effect similar to an unfocused image. 

Here, too, the size is given in percentage, like in Sharpen 


═══ 7.23.7. Emboss ═══

Emboss is an effect of a relief with color loss occurs. 

The depth in area 1 to 16 shows the intensity of various relief levels or 
light/shadow shadings. The direction arrows define the direction of the the way 
the shadow falls. 


═══ 7.24. Impos/2 settings ═══

The selection Settings2 opens a notebook over which tabs pre-settings for 

o Screen Shot (Capture from display), 

o Background of image window and 

o General 

can be made. 

All changes are immediately active. To undo changed settings, the push button 
undo should be used before closing the settings; it puts you back to the 
position of the group when having first called the settings. 


═══ 7.24.1. Help for dialog Settings background ═══

With the background base color and pattern of an image window can be selected. 
This background becomes visible, if the image itself is smaller than the image 
window; in this case it is centered within the image window. 

The cover color shows the color of the pattern which is drawn on the base 
color. The pushbutton Default puts the background on a rastered black-and-white 
pattern. 

The setting of the background can lead to a visible optical improvement in 
screens with high resolution and low repetition frequence. 


═══ 7.24.2. Help for dialog Setting General ═══

This group controls the color display and the behaviour when closing one of the 
image windows. 

o Dynamic color adjustment 
  With screen cards with 256 colors from over 16 million possible colors only 
  256 colors can be presented at the same time. The active image defines the 
  palette of these 256 colors. The colors of the images in the background can 
  appear totally wrong. When selecting the dynamic color adjustment Impos/2 
  tries to present the images in the background with the best possible 
  available colors of the foreground image. This adjustment requires a certain 
  calculation time which when working with lots of images can lead to a delay 
  of a few seconds. 

o Closing of a changed image 
  If an image was changed in any way after last saving, a security questioning 
  can be switched on and off, which stops the accidental closing. 

o Closing of a new image 
  The closing of a new image which was e.g. captured via screen shot function 
  or via scanner, can have a security questioning, too. 

The pushbutton Default switches dynamic color adjustment off and the 
questioning options on. 


═══ 7.24.3. Help for dialog Setting capture from screen ═══

This dialog enables pre-settings for the function Capture from screen 

Within the group Capture from wird the capture area is preset: 

o whole screen 
  The whole screen content with all windows is captured. 
o Whole window 
  A single application window (or a window with frame within an application) is 
  captured. 
o Window content 
  Only the work area (within the frame) of a window is captured. 
o Window element 
  A single element of a window like e.g. an entry field or the title bar is 
  captured. 

The further options control the take-over itself: 

o Time delay 
  This spin button is only active if the take-over option Whole screen was 
  selected. In this case the take-over can be delayed by the given number of 
  seconds (1 to 30), in order to e.g. open up a submenu within the action bar 
  of an application which is to be shown when displaying the whole screen. In 
  this case a short tone sounds after every second which can estimate the time 
  of take-over by counting. 

o Take over mouse pointer, too 
  This checkbox enables the take-over of the mouse pointer into the captured 
  image. If this option is not switched on, the mouse pointer is faded out 
  throughout the period of take-over. 

o Hide Impos/2 window 
  With this option the Impos/2 window can be hidden during take-over, which 
  means it is not captured itself. 

The set values are constantly saved and thus are available when re-starting 
Impos/2. 

The pushbutton Undo puts back to the position/level when first calling the 
settings. 

Default sets the pre-settings 

o take-over from whole screen 
o Hide Impos/2 window

Resolution 

Resolution of an image is defined by number of pixels per length unit. Normally 
it is shown in dpi (Dots/Inch) or lpc (Lines/cm). 


═══ <hidden>  ═══

Pixel = picture element 

Individual pixel in electronic image data. An image (or picture) is built up of 
a number of row-oriented or column-oriented pixels. 


═══ <hidden>  ═══

dpi = Dots per Inch 
dpm = Lines per cm 

The resolution dpi or lpc indicates how many pixels per length unit an image 
has. A resolution of 300 dpi e.g. has 300 pixels per inch, which means 2,54 cm 
has 300 pixels. 

Sometimes dpm (dots per meter) is used instead of lpc - for exacter definition 


═══ <hidden>  ═══

Inch 

The english length unit Inch corresponds to 2,54 cm. In data processing it is 
often used for definition of resolution. 


═══ <hidden>  ═══

Dot 

Single pixel e.g. in electronic image data. An image (or picture) is built up 
of a number of row-oriented and column-oriented pixels. 


═══ <hidden>  ═══

Bit 

Smallest information unit in data processing. Electronically a bit is realized 
as switch, which can take up the condition on (true or 1) or off (false or 0). 
These switches are summarized to groups of 8 known as Byte. 

In image processing a bit is used for example to represent a pixel in a 
black-and-white image, which means on means white, off means black. 


═══ <hidden>  ═══

Byte 

The unit of memory is called Byte. A Byte can be considered as number between 0 
and 255 and is put together out of eight Bits. 

In image processing a  Byte is used for example to represent a pixel in a 
grayscale image of 256 different grayscales which means the value 0 means 
black, the value 255 means white. 


═══ <hidden>  ═══

True colors 

True color images are made up out of the three colors Red, Green und Blue with 
256 shades each. To get the color black, all three color components are given 
with the intensity 0. The color white is reached out of the maximum color 
intensities 255 (additive). This color resolution suits the demands which are 
e.g. necessary for the quality printing, but requires 24 Bits per Pixel or 3 
Bytes, which has a very high need of memory as result. 


═══ <hidden>  ═══

Color palette 

Images with a certain number of fixed colors are defined over a color palette, 
which means a table with true colors is stored to the image. Then the 
individual pixels do not contain the color itself but an index to the colors in 
the color palette. Thus for an image with 256 green tones e.g. only one index 
between 0 and 256 can be stored for every pixel (1 Byte)instead of leaving 
every single pixel in true colors (3 Bytes). 


═══ <hidden>  ═══

Color resolution 

Color resolution is the number of colors that are used in an image at the same 
time. 

A black-and-white image has for example a color resolution of 2 colors. A true 
color image has a color resolution of approx. 16,8 million colors. 


═══ <hidden>  ═══

Grayscales 

A grayscale image consists only of gray tones, like e.g. a black-and-white 
photo. The reproduction quality is marked by the number of different grayscales 
or gray tones, whereby 256 gray tones nearly shows photo quality. 


═══ <hidden>  ═══

Bitmap 

The term bitmap is used in various meanings. On the one hand bitmap is used as 
synonym for raster images. On the other hand bitmaps are known as special image 
storage format under OS/2* or Windows* with file extension BMP. 


═══ <hidden>  ═══

Desktop Publishing 

Desktop Publishing is known to be the production of publications suitable for 
printing made at the desk (Desktop). With help of modern applications printed 
materials of high quality can be produced with a PC, where in early days 
special and expensive methods had to be used. 


═══ <hidden>  ═══

Scanner 

Scanners (in image processing) are used for digitalization of images. A 
photoelectric element is guided across (scans, hence the name) the image line 
by line and transmits the individual pixels to the computer. 

Many constructions of scanners exist. For example: 

o In a flatbed scanner the document is put in like in the photocopier, the 
  photoelectric element is then moved across the image for scanning. 
o In a drum scanner the document is mounted on rotating drum for scanning. The 
  photoelectric element is fixed. 
o The hand scanner is small and lightweight and can be guided over the document 
  manually. 

Apart from that special document feeders (similar to a photocopier) are used to 
scan stacks of documents. 


═══ <hidden>  ═══

Spinbuttons 

In a spinbutton field settings can be made within a given range of values or a 
set of predetermined settings. Often a default setting is displayed; this can 
be changed in three ways: 

 1. with the mouse, by pressing the arrow symbols of the spinbutton field with 
    the left mouse button, 

 2. with the control keys  , or 

 3. by directly entering the desired setting by using the keyboard. In general 
    only entries within the appropriate range are accepted. The direct entry 
    via the keyboard is not possible with all spinbutton fields. 


═══ <hidden>  ═══

Toolbar 

The toolbar in the top part of the window allows for direct selection of often 
used functions via a row of icons by using the mouse. The functions are 
available via the toolbar as well as the action bar. 


═══ <hidden>  ═══

Action bar 

The action bar in the top of the window is used to select actions or commands. 
It is implemented as a menu with several levels, by dropping a menu down for 
every entry. These menus can contain further submenus. 

The action bar is activated with the F10-key, the menu options can then be 
selected with the arrow keys. 


═══ <hidden>  ═══

Slider bar 

A slider bar allows the simple and fast value selection within a given range. 
The slider button can either be clicked onto and moved with the left mouse key 
or can jump to a specific position by clicking with the right mouse key. The 
slider bar also reacts to the arrow keys. 


═══ <hidden>  ═══

Pushbutton 

A pushbutton starts a certain action. Normally it is clicked onto with the 
mouse. Generally a default pushbutton exists, which is marked by a dark frame. 
The action of this pushbutton begins when pressing the Enter-key (usually) OK). 


═══ <hidden>  ═══

Checkbox 

A checkbox enables turning an option on or off. By clicking with the mouse or 
pressing the spacebar (if the box is focused) the marking is changed. 

Picture left half: marking switched on 
Picture right half: marking switched off. 


═══ <hidden>  ═══

Clipboard 

OS/2* administrates the clipboard. It provides storage for applications to 
exchange objects of certain formats (e.g. texts and bitmaps) to be included 
once again in other applications. Only one object at a time can be stored in 
the clipboard (if necessary in several formats).
