ΓòÉΓòÉΓòÉ 1. Extended help for "Open Image" ΓòÉΓòÉΓòÉ
This dialog is where the name of the file to open is specified. There are four
areas of interest on this dialog:
o Format area
o Files area
o Directories area
o Pushbutton area
The "format area" is where you select the format of the file you wish to load.
If you want the Image Toolkit to determine the format for you, select
"(Determine the file format)".
The "files area" is where you see the files in the current directory.
Double-clicking on a file in this list is the same as selecting the file and
then selecting the "Open" pushbutton.
The "directories area" is where you see both the subdirectories beneath the
current directory and the available drives from which to choose.
Double-clicking on a file in this list is the same as selecting the directory
and then selecting the "Open" pushbutton.
The "pushbutton area" contains the pushbuttons corresponding to the available
actions that can be performed on this dialog.
"Open" will either opens the currently selected or entered file, refreshes the
file list with the specified filename mask, or changes to the specified
directory. The order of precedence is as follows: if a filename has been
entered or selected and does not contain any "wildcard" characters, this will
attempt to open the file and load the image contained therein; if the filename
does contain any "wildcard" characters, this will refresh the file list using
the specified filename mask; else, this will change the current directory to
the one entered or specified.
If nothing is entered and nothing is selected, it is taken as though "*.*" were
entered in the filename area.
"Properties" will display the format-specific properties dialog, allowing you
to specify any format-specific options to be used upon loading. It is the
decision of the format handler to use the specified options or not.
"Cancel" will return you to the previous window with no action taken.
"Help" will display this panel.
ΓòÉΓòÉΓòÉ 2. Extended help for "Save Image" ΓòÉΓòÉΓòÉ

The "files area" is where you see the files in the current directory.
Double-clicking on a file in this list is the same as selecting the file and
then selecting the "Save" pushbutton.
The "directories area" is where you see both the subdirectories beneath the
current directory and the available drives from which to choose.

ΓòÉΓòÉΓòÉ 3. Extended help for "Print Image" ΓòÉΓòÉΓòÉ
This dialog is where you specify the printer and the printing options to be
used. There are five areas of interest on this dialog:
o Printer list
o Alignment area
o Options area
o Printer page
o Pushbutton area
The "printer list" is where the currently installed printers are listed, with
the default printer selected when the dialog is initially displayed.
The "alignment area" is where you can "snap" the image to a particular side or
the center in both the horizontal and the vertical directions.
The "options area" is where you can select any additional options to apply to
the print job.
Print to file By checking this checkbox, you can enter a file name to
which the printer output will be spooled. To obtain a
hardcopy from this file, you simply need to copy the file
to the printer.
The "printer page" is a depiction of the printable area for the printer you
have selected. Here you can manipulate the image by using mouse button 1.
When the pointer is in the middle of the image, depressing the button will
allow you to change the position on the printer page, while depressing the
button when the pointer is positioned on one of the image edges allows you to
change the size of the image in the direction corresponding to the edge the
pointer is on.
Selecting a new printer in the printer list automatically resizes the printer
page.
The "pushbutton area" contains the pushbuttons corresponding to the available
actions that can be performed on this dialog.
"Print" will attempt to print the image using the options specified on this
dialog on the selected printer.
"Properties" will display the printer-specific job properties dialog allowing
you to specify any printer-specific options to be used when printing.
"Cancel" will return you to the previous window with no action taken.
"Help" will display this panel.
ΓòÉΓòÉΓòÉ 4. Extended help for "Image Window" ΓòÉΓòÉΓòÉ
This is the main window where all actions are performed. There are three areas
of interest (annotated in the picture above):
o The action bar
o The display area
o The miniature view
The action bar is where all of the actions are selected from. By moving the
cursor to an item and pressing F1, you can get help for that menuitem.
The display area is where the image is displayed. It is this area that is
manipulated by subsequently selecting any of the appropriate menuitems.
Actions such as saving and printing can be performed.
(The miniature view is not used at this moment) The miniature view is used for
drag-n-drop purposes. When used with applications that support the private
format used by the Image Window, you can copy the contents of the display area
to other appplications without going through the clipboard. The advantage of
doing this is that you don't lose what is currently in the clipboard.
ΓòÉΓòÉΓòÉ 5. Extended help for "Dither options" ΓòÉΓòÉΓòÉ
Use the "Dither options" dialog to set the dithering options to be used for
this window. On the dialog, three spinbuttons allow you to choose the
dithering pattern type, size, and the darkness to be used when dithering an
image.
For more information, double click on one or more of the following topics:
o Dithering
o Dithering pattern type and size
ΓòÉΓòÉΓòÉ 6. Extended help for "Image Information" ΓòÉΓòÉΓòÉ
Use the "Image Information" dialog to get information about the currently
displayed image. The following fields are currently displayed:
o Format name
o Format author
o Width
o Height
o Color planes
o Bits per pel
The format name field describes the format that the image was in when it was
originally loaded from the disk where it resides.
The format author field specifies the author(s) of the format handler used to
load the image from the disk.
The width field specifies the image width in pels.
The height field specifies the image height in pels.
The color planes field specifies the number of color planes used for the image.
This is a display adapter dependent number, usually.
The bits per pel field specifies the number of bits used to describe the color
of one pel. The total number of colors in any bitmap is, therefore, 2 raised
to the power of this number. The common values are 1, 2, 4, 8, yielding 2, 4,
16, and 256 colors, respectively.

Selecting this menuitem displays a dialog allowing you to print the selected
area on any local printer queue. Additionally, you can change the destination
size and position on the printer page.
For LAN printers, the following conditions must be met:
There must be defined a local queue associated with a local printer definition.
The printer definition must use the same printer driver that is used on the
server for the printer in question.
The port number (e.g. LPT1, LPT2, etc.) specified in the queue must match that
which is used on the "NET USE" command.
When PM sees an application spooling a print job to the local queue, it
determines that this is to be printed on a LAN printer by the matching port
numbers, so it sends the print job over the LAN to the server automatically.

ΓòÉΓòÉΓòÉ 40. Dithering ΓòÉΓòÉΓòÉ
Dithering is the process of converting a color or greyscale image to monochrome
while preserving the contrast of the individual colors in the original image.
The dithering process involves overlaying a two-dimensional pattern of
weighting values on top of the original image in a quilt-like fashion. If the
average of the color in the image is greater than that of the corresponding
element in the dithering pattern, the proper pel in the destination image is
set.
The image colors are averaged with each component (red, green, and blue)
weighted according to the natural eye sensitivity to that component.
ΓòÉΓòÉΓòÉ 41. Dither pattern type and size ΓòÉΓòÉΓòÉ
There are four dithering patterns that IBrow can use - diagonal, diamond,
circle, and square. Each pattern comes in 3 sizes - 4x4, 6x6, and 8x8. Use
the spinbuttons on the dialog to select the values to be used when dithering.
