DISCLAIMER:
VESAVIEW is offered to you on an as-is-basis without any guarantee as to the
correct functioning or fitness for a specific purpose. The author believes
this program to work as described but you use the program entirely at your
own risk. The author will not be responsible for any hardware or software
damage, loss of data, or incidental or consequential damage that may result
from its use, whether or not such use is in accordance with the instructions.
REQUIREMENTS:
o IBM compatible 286 or better
o Extended memory (and driver such as HIMEM). For 256 (& higher) color
files, you'll need 1 byte/pixel in your image. For 2 color files,
you'll need 1 byte per 8 pixels in your image. This program conforms to
XMS 2.0 specification. 8MB of extended memory is recommended expecially
if you will be using graphic array menus and working with JPEG files.
o Will use a math coprocessor if available
o A graphics card that supports the VESA BIOS EXTENSIONS for the 'Super
VGA modes' either through hardware or a software driver. NOTE: If no
VESA driver is found, you will be limited to 320x200x256 or 640x480x2
non-VESA modes which won't allow arrays to be generated.
FEATURES:
o Will read in any size up to 1280 x 1024:
BMP (Windows) - 16, 256 color & 24 bit (16 million colors)
GIF (Compuserve 87a/89a) - 16 & 256 color
IMG (GEM/Digital Research Inc) - B & W
JPG (JPEG/JFIF) - Grayscale & 24 bit (16 million colors)
PCX (Zsoft) - 2, 16, 256 color & 24 bit (16 million colors)
TGA (Targa) - 8,16, 24 & 32 bit (non-compressed RGB & Run length
encoded RGB)
TIF - B & W, 16c, 256c & 24 bit (non-compressed & run length
encoded)
HPG - (Hewlett Packard) HPGL plot files (.HPG or .PLT)
o Files can be selected either from a text directory listing or
graphically from a previously created array of images (mouse required
for graphic selection). Multiple selections are displayed in the order
selected.
o If the file is larger than the screen mode you selected, you can quickly
pan around the image. Size of image is limited only by the amount of
extended memory you have. NOTE: The entire image is read into Extended
memory to allow for quick panning of large images. Black & White images
are stored in memory with 1 byte per 8 pixels. 16 (4 bit) and 256 color
(8 bit) images are stored in memory with 1 byte per pixel. 24 & 32 bit
images are stored in memory as 256 color images so only 1 byte per pixel
is required.
o Black & White printing (color images will be halftoned) and Color
printing are supported. Prints can be sized, rotated and positioned on
paper. Printers supported are HP LaserJet Series, DeskJets, DeskJet
500/500C/550C, PaintJet, PaintJet XL, and PaintJet XL300.
o Red/Blue/Green/Contrast/Brightness values may be changed while viewing
a color image. Image can be converted to GrayTone.
o Color screen images can be saved as a 256 color BMP, GIF, JPG or PCX
file. These images may be cropped & scaled before saving.
o Black & White images can be saved as an IMG or 2 color PCX file. This is
useful to save a HPGL file that is displayed on screen out to a quicker
retrieving raster file. If these images are displayed in a color VESA
mode they can also be saved &/or cropped as 256 color BMP, GIF, JPG or
PCX files.
o Arrays of up to 81 images can be displayed on a single screen at once.
This screen can then be saved as a single BMP, GIF, JPG or PCX file for
cataloging or printing or use as a graphic menu for VESAVIEW.
o Supports VESA modes (assuming your graphics card can handle):
100 - 640 x 400 x 256
101 - 640 x 480 x 256
103 - 800 x 600 x 256
105 - 1024 x 768 x 256
107 - 1280 x 1024 x 256
o Will support a 800 x 600 x 2 color B&W mode if your card has one. (See
/SVn option below)
o Supports the use of a MicroSoft compatible 2-button mouse.
NOTE: The annoying beeps and NON-Registered notices will be removed from
registered copies. Also, the NON-Registered version does not
support the new printing options (sizing, rotating and
positioning), nor the Compressing of printer data.
RUNNING with COMMAND LINE QUALIFIERS:
Make sure you have enough extended memory available and that a driver (such
as HIMEM) is loaded. Make sure your graphics card has VESA BIOS EXTENSIONS
(VBE) either built-in or that you have installed a VESA software driver.
Keyin:
VESAVIEW [/AB or /AW] [/AMmode] [/AS] [/CS, /CO or /COD] [/Dn] [/Fn]
[/FN, /FB or /BW] [/FTMn] [/LOmode] [Mx] [/NB] [/NLAM] [/P1, /P2 or /PF]
[/PAn] [/PC] [/PGn] [/PLMn] [/PRn] [/PTMn] [/PSBH, /PSBS, /PSCH or
/PSCS] [/PTDJ, /PTLJ, /PTPJ, /PTPJXL, /PTPJXL3, /PTDJC or /PTDJ5C]
[/PWn] [/PXSn] [/PYSn] [/SVn] [/UPSA, /UPSB or /UPSC] [/WN, /WH or /WF]
where items in brackets are optional.
CAUTION: DOS has a limitation of 127 characters on the command line. If you
exceed this when adding qualifiers, some may be truncated.
NOTE: Underlined (or *) qualifiers are only available in the REGISTERED
VERSION. The optional qualifiers can also be changed while in the program by
pressing <O> (or pointing to OPTS with the mouse). These changes are only
for the current session and will not be saved. A 'space' is needed between
each qualifier on the command line. If you wish to use the same qualifiers
each time you evoke the program, write a BAT file like:
CD \GIF rem Assumes your graphics files are here
\VV\VESAVIEW /P1 /NW /CO rem Assumes program in VV dir
The /AB forces the array mode to use a black background and white text for
the filenames.
The /AW forces the array mode to use a white background and black text (saves
black ink when printing).
The /AMmode (where mode is 100, 101, 103, 105 or 107) will let you default to
a specific mode when displaying arrays. The program will default to mode 101
if this switch is not used. Only use a mode number that your card can
support!
The /AS (array sizes) enables the display of image sizes above each image of
an array. The size will be displayed after the filename of each image only
if it will fit. Typically at a resolution of 1024x768, the sizes will fit on
6x6 arrays and below. At 800x600, the sizes will fit on 5x5 arrays and
below. At 640x480, the sizes will fit on 4x4 arrays. Each image is tested
individually, so on a given array screen, some sizes may appear and some may
not. You will see the sizes displayed after all images on a page have been
processed.
The /CO (color-optimized) will force 16, 24 & 32 bit images to be processed
using an optimized 256 color palette. The process reads in all the colors in
your image, creates a histogram of the most used colors, and then creates an
optimized palette of the results. The processing time is greater than if the
/CS option is used, but the results are spectacular. The color reduction
method used is much faster than that of other program that I have tested.
After the image has been displayed on the screen, you might want to save it
as a 256 BMP, GIF, JPG or PCX file, so that the next time you want to display
it, you can use the quicker 256 color version.
The /COD qualifier is similar to /CO above, expect that besides using an
optimized palette, the image will also be dithered to smooth out the
transition between colors.
The /CS (color-standard) will force 16, 24 & 32 bit images to be displayed
using a standard palette. The colors will be adequate for previewing, but
for more exact colors, use the /CO.
The /Dn (delay) is for setting the delay in seconds to use between slides.
The n is an integer number from 1 to 999 and defaults to 5 seconds. This
time is approximate and will vary depending on the size of the image being
read in.
The /Fn (fade) option will fade in and out your images on screen when
displaying them as a slide show. The n can range from 0 to 10. 0 is no
fade, 1 is the fastest fade and 10 is the slowest fade.
The /FN, /FB or /FW specify the foreground color (N=none, B=Black and
W=White) of your Black & White images. By specified foreground color, the
program will be able to save more of your image's original context when
scaling down. This qualifier works best if your images are line drawings and
not pictures. For example, if your image appears on the screen as black
lines on a white background, use the /FB qualifier. If your images don't
have a main foreground color such as the case with pictures, use /FN. Note
that using either the /FB or /FW qualifiers will increase the processing time
for B&W scaling. If you don't need the increased quality, use /FN.
The /FTMn (fixed top margin) option will allow you to override the program's
default values for that part on the top of a page that your printer can't
print on. The defaults are:
0.1" - DeskJet, DeskJet 500, DeskJet 500C
0.05"- DeskJet 550C
0.0" - LaserJet Series, PaintJet XL, PaintJet XL300
0.0" - PaintJet (tractor feed)
If your printed margins don't match what you set in the Printer Setup Menu,
then use this qualifier to adjust them.
The /LOmode (lockout mode) (where mode is 100, 101, 103, 105 or 107) will
lock out a mode. This is useful if your VESA driver is designed for a
graphics card which has been fully populated with memory chips but your card
doesn't have all of this memory installed. You may use more than one of
these switches on your command line.
The /Mx (mask for filenames) will allow you to include only certain file
types in your directory listing. It can be one of the following: /MALL
(all filenames), /MDIS (all displayable graphics files), /MBMP (only *.BMPs),
/MGIF (only *.GIFs), /MIMG (only *.IMGs), /MJPG (only *.JPGs), /MPCX (only
*.PCXs), /MTGA (only *.TGAs) /MTIF (only *.TIFs). Note: Array index files
(.VNX) are always accessible by the program, even if they are not being
displayed in your directory listing. Caution: When you use this qualifier
to eliminate the display of certain file types from your screen, and you
display a previously created array image that includes file types that are
not currently displaying, those files will not be found even though they are
actually in the directory. (they will be flaged on screen with a red
crosshatch)
The /NB (no beep) option will disable the beeps after images are displayed on
screen. The default is to beep.
The /NLAM (no load array into memory) will disable the automatic loading of
the first graphic array menu into XMEM even if there is enough memory to do
so. The program by default will load the first array image that will be used
as a graphic menu into XMEM, if there is enough memory to hold this array and
one more image (both are assummed to be the maximum size of 1280x1024x256).
If you are low on XMEM and you wish to be able to pull up larger files (B&W
for example) from the array menu, you will probably need to use this
qualifier.
The /P1 or /P2 (port) designates which printer port to use for printing (LPT1
or LPT2).
The /PF option forces printer output to a file instead of a port. The file
will be created in your current directory with the same filename as your
image file but with an extension of .VVP . This option works with multiple
plots as well. No checking for duplicate filenames is done. To plot the
file(s), from DOS keyin:
COPY/B filename.VVP LPT1:
where filename could be a wildcard and LPT1: could be LPT2:. The /B
instructs DOS to use a binary copy mode.
The /PAn (print angle) is used to rotate your print on the printed page.
Values for n can be 0, 90, 180 or 270.
* The /PC (print compress) option will force the transfer of data from your
computer to the printer to be in a compressed (encoded) format. This will
speed up the transfer of data (especially for serial or networked printers).
Time savings will vary depending on the type and size of plot. In some
cases, you may find no time savings overall since the printer has to
decompress the data, but your CPU should be freed up from processing sooner.
(default is no compress). The PaintJet and LaserJet II don't support this
type of data compression. If your printouts look garbled, don't use this
qualifier.
The /PGn (print gamma correction) option will allow you to adjust the gamma
of your Black & White or Color print. Simply put, gamma correction will
adjust the intensities of red, green & blue values logarithmically since the
human eye's perception of color intensity is non-linear. The gamma value is
a decimal value between 0.5 and 2.0. If set to 0, no gamma correction will
be performed. If this qualifier is not used, gamma defaults to a value best
suited for the printer type selected. Using higher values will result in the
darker colors in your image being printed lighter and the lighter ones
remaining the same. This gives a much more natural looking printout.
* The /PRn (printer resolution) is used to specify the resolution in dots per
inch (dpi) of your active printer. For the DeskJet series, it can be 75, 150
or 300. For the PaintJet series (except XL300), it can be 90 or 180.
Defaults to highest resolution for selected printer.
The /PXSn and /PYSn (plot scale) qualifiers can be used to slightly adjust
the X-scale and/or Y-scale of your B&W plots. These are useful if your plot
needs to be an exact scale and your printer is not scaling the plot the same
in the X & Y directions. Increasing the /PXSn parameter will lengthen the
plot along the 8 1/2" dimension and increasing the /PYSn parameter will
lengthen the plot along the 11" direction. The defaults for n are 1.0 and
their ranges are between 0.9500 and 1.0500. For example, on my DeskJet I use
/PYS1.005 and /PYS1.015.
The /PSx (print style) option allows you to select the style of printing for
Black & White or Color prints. It can be one of the following: /PSBH (B&W
Halftone), /PSBS (B&W Scatter), /PSCH (Color Halftone) or /PSCS (Color
Scatter). The Halftone styles will process much faster than the Scatter
dithering types which use an error difusing algorithm, however, the Scatter
styles will in most cases have much better detailing and quality. Halftoning
is the default.
The /PTx (printer type) is used to select your printer. It can be one of the
following: /PTDJ (HP DeskJet), /PTLJ (HP LaserJet), /PTPJ (HP PaintJet),
/PTPJXL (HP PaintJet XL), /PTPJXL3 (HP PaintJet XL300), /PTDJC (HP DeskJet
500C) or /PTDJ5C (HP DeskJet 550C).
* The /PWn (print width) is used to specify a print width. It is a decimal
value from 0.0 to 10.5. If you enter a number greater than 8.0, the print
will automatically be rotated 90 degrees. The print width represents the
width that you want the horizontal image dimension as seen on your screen to
be printed, no matter what rotation angle you use.
* The /PTMn (printer top margin) sets the number of inches from the current
position of printhead that the image will start printing. It is a decimal
value ranging from the minimum value of your printer (see /FTMn above) to
10.0. If set to 99, your image will be centered from top to bottom.
* The /PLMn (printer left margin) sets the number of inches from the left side
of page that the image will start printing. It is a decimal value from 0.25
to 7.5. If set to 99, your image will be centered from left to right. The
maximum printable width on all printers is 8.0" (1/4" left & right margins).
The /SVn (SVGA) will allow you to use a 800 x 600 x 2 color mode to display
IMG or HPGL files in a high resolution mode if your graphics card supports
it. The n is the decimal mode number that your card uses for this mode.
Most Paradise cards use 41 decimal for this mode, and the Tseng cards
(including Orchid) use 89 decimal. This special mode and the standard 640 x
480 x 2 mode will allow faster panning on screen than the same resolutions in
VESA modes will for large B & W images. NOTE: The panning icon which is
available in VESA modes is not available for B & W modes.
The /UPSA, /UPSB & /UPSC (unknown plot size) qualifiers will allow the user
to specify a default plot size (A, B. or C) if the program that created the
.PLT file did not include the HPGL cmd PS to signify what the Plot Size was.
If one of these qualifiers is not used, and the .PLT file doesn't have a PS
cmd, VESAVIEW will default to a 'C' size plot.
The /WF (full weights) will display the weights as originally drawn.
The /WH (weight half) is similar to /WN except that the weights of lines will
be halved (divided by 2).
The /WN (weight none) will not display weights of lines in an HPGL plot file
if the SP (select pen) keyword was used when creating the plots. This will
greatly speed up the screen drawing if you don't need to look at or print the
weights. Some CAD programs which generate the plot files create weighted
lines by simply drawing the lines multiple times in the plot file (each
slightly offset) and not by using the SP (set pen) command. The /WN & /WH
switches will have no effect on this type of plot files.
SYSTEM DEFAULTS: /AB /AM101 /COD /D5 /F0 /FB /MALL /P1 /PTDJ /PW8.0 /PA0
/PTM0.25 /PLM0.25 /PXS1.0 /PYS1.0 /UPSC /WF
Ex: VESAVIEW /P2 /AW /D10 - Will use printer port LPT2:, display
arrays with a white background, and delay 10 seconds between slides.
Ex: VESAVIEW /LO105 /LO107 /AM103 - Will lockout modes 105 and 107 from
being valid VESA modes and will use mode 103 when displaying arrays.
The program will test to see if your graphics card supports the VESA Bios
Extensions by either hardware or software driver, whether you have a HIMEM
driver loaded and how much extended memory you have available.
Use the <ESC> key to exit program. A mouse button can not be used to exit
the program.
CHANGING DIRECTORY:
While the list of files is on your screen, you can change your current
directory by placing the cursor on the lite blue entries (which are directory
names) and pressing <ENTER>. The . (single dot) will take you back to the
root directory, and the .. (double dots) will take you back one directory
level.
You can also press the <C> key (or point to CDIR with mouse) to keyin a new
path that can include a new disk drive. (Ex: B:\ or C:\GIF or C:\IMAGES\GIF
or \GIF)
VIEW SINGLE IMAGE (from Text directory):
To view a single image move the cursor (with arrows, pageup, pagedown, home
or end keys) to the desired image file and press <ENTER>. Then select a Vesa
Mode from the Mode Menu. An asterisk denotes the Best Mode (calculated by the
program) which will display the most of your entire image on a single screen
in the best resolution. After your image is displayed, press <ESC> (or right
mouse button) to return to main menu. Note that when viewing IMG files or
HPGL files, you can use a VESA mode (only B&W colors used), use the standard
640 x 480 x 2 mode or use the Super VGA mode that you optionally entered on
the command line. Entries in gray on the Mode Menu are not available for
your graphics card.
VIEW MULTIPLE IMAGES (slide show) (from Text directory):
To view multiple images as a 'slide show', use the <Space Bar> (or right
mouse button) to select the images you wish to view. You can mark all images
in the current directory with the <M> key (or point to MARK with mouse) or
unmark them with the <U> key (or UNMARK with mouse). These can include BMP,
GIF, IMG, JPG, PCX, TGA, TIF, PLT and HPG files. By pressing the <C> key,
you can change your current Disk &/or Directory. Press <ENTER> (or left
mouse button) to start the slide show. The files will be displayed one by
one in the best VESA mode as determined by the program (640x480x2 mode is
used for PLT & HPG files). The delay between slides will vary depending on
the time it takes to read in the next file while one is on your screen and
the value used in the /Dn switch. Fading in and out between multiple images
can be done by using the /Fn switch. After the last file is displayed, the
program will loop back to first slide. Pressing <ESC> (or right mouse
button) during the display will stop the slide show. (this may take several
seconds). Note: Files will be displayed in the order in which they were
selected. You can pause the slide show by pressing the <Pause> key on
keyboard. Any other key will continue the show.
VIEW / CREAT AN ARRAY OF IMAGES (from Text directory):
To view multiple images on a single screen at once, use the <Space Bar> (or
right mouse button) to select the images you wish to view. These can include
BMP, GIF, IMG, JPG, PCX, TGA and TIF files but not PLT or HPG files. Press
<A> (or point to ARRAY with mouse) to select array display. Select the VESA
mode from Mode Menu and then select the number of images to display per
screen page. Then sit back and watch your images appear. Pressing <ESC> (or
right mouse button) will abort the display after the current image is
displayed. After each page is displayed, you could press <B> to save the
currently displayed page as a Windows BMP file, <G> for GIF file, <J> for JPG
or <Z> for ZSoft PCX file or <PAGE DN> will continue to display the next
page.
If you used the /AS qualifier or selected 'Show Array Sizes' from the Options
Menu, the image sizes will be displayed alongside the filenames.
Since each image uses it own unique 256 colors, a special optimized color
table and color dithering is used to display arrays. Note that when
displaying a 2-color file in an array, the scaling down of the original image
(especially a line type drawing) will cause much of the info to be lost on
the screen unless the /FB or /FW command qualifier is used.
Creating arrays of your images is a good method of saving a sequence of
images for a slide show. They are saved in the array in the order you
selected them. To play them back, just pull up that array image, press 'M'
to mark all images, and press left mouse button to display them.
NOTE: Arrays are only available in VESA modes. Files will be arranged in
the array in the order in which they were selected.
AUTO ARRAY GENERATION/SAVING:
If you are going to have many pages (screens) of array images and you will be
saving them all out as single files, you can do this automatically by the <G>
(or point to AUTO/GEN with mouse) to activate the generate option. This will
automatically display the arrays on the screen and then save them out without
any user intervention until the last one is processed. You begin just as you
would for the standard array option by selecting the files to display, the
VESA mode, and then the number of images/page. You are first prompted for the
file type to use when saving. Then you are prompted for the first 1-6
characters of the filename that the program will use for the files it
generates. You may precede the filename with a Disk & Directory if you don't
want to use the current Disk/Dir. The system will append a 2 digit page
number and appropriate extension to your input.
EX: You are going to have 3 pages of array images and you select <G>IF as
the filetype and enter TEST as the filename. The System will generate 3
files named TEST01.GIF, TEST02.GIF & TEST03.GIF.
VIEWING FILES (from a previously created Array image):
If you have previously created and saved an array of images, you can use it
to graphically select the images you want to display either singularly or as
a slide show or for plotting. NOTE: A mouse is required for this mode. Just
select the array image from the Text directory listing. After it is
displayed, use the box shaped cursor to select the files. The left mouse
button will select one file and display it immediately. The right mouse
button is used to Mark/Unmark files for a slide show or multiple plotting.
Files are outlined with a red box when they are marked. If a file on your
array menu does not exist in your current any more, the file will be cross-
hatched with red lines. After all files you desire are marked, press the
left mouse button to start the display. The /Dn and /Fn (delay and fade)
work with multiple selections from arrays. Files will be displayed in the
order that they were selected on the screen. If you want to display all of
the files in the same order they were created, just press 'M' to mark them
all, and press the left mouse button to start the show. NOTE: Normally a
right mouse button is used to Quit the current image, but since that button
is used to Mark/Unmark files in the array menu, you must simultaneously press
both the left and right button to Quit. You can still use the <ESC> key to
quit.
Array images created before VESAVIEW version 4.0 will not allow graphic file
selection. Version 4.0 and above creates an additional index file for each
array image you create. This file will have the same filename as your array
image but with an extension of .VNX . If this files does not exist in the
same directory as your array image file, you will not be able to use the
array image as a graphic menu, but you can still view it as a normal image.
The index file is very small, and unlike other graphic packages which allow
graphical selection of images from the screen, VESAVIEW does not require
separate THUMBNAIL files for each image which saves considerable time and
disk space. As of version 4.3, the array image together with its index file
may be stored (or saved) on a Disk/Directory that is different from the
location of the images in the array. This will allow users to catalog images
from CDROMs (which can't be written to) etc. VESAVIEW assumes that if your
array images have nested arrays, all of these arrays are located in the same
directory, but each of the array's images can be located on different
Disk/Directories if needed. The index file stores the Disk & Directory of
the images in the array. NOTE: If you ever move your images from where the
array was initially created, you will either need to re-catalog them or use
a text editor to change the path (first entry) in the .VNX file. To make the
index file downward compatable with versions prior to 4.3, the program will
accept index files that didn't store the images path in them as the first
entry.
Up to six levels of array menus can be used (nested). For example, you could
have one array image that had other array images in it. One idea would be to
have individual array images for BMPs, GIFs, JPGs, PCXs and TGAs. Then have
a master array image which would include the BMP, GIF, JPG, PCX and TGA
arrays. While an array image is displayed, selecting another array image
from it will pull up that new array menu and so on. If you have displayed an
image out of a sub-level array menu, the <ESC> or right mouse button will
return you to the previously displayed array menu. (remember that if you are
displaying an array file, you must use both the left and right mouse button
together to return to previous image).
If you need to add or delete an image from the array image, you will need to
re-create it. New array images can only be created from the Text directory
listing.
Additional Keys available while displaying an array image:
M1 (left mouse button) Used to start displaying a single or marked
multiple images
M2 (right mouse button) Used to Mark or Unmark files
M1 & M2 (together) Used to Quit from an array image
(See 'SPECIAL KEYS WHILE VIEWING' later for standard keys available)
Warning: You cannot have different array files with the same filename and
different extensions in the same directory since each file will use the
extension .VNX for its index file. Ex: You cannot have DIR01.GIF and
DIR01.BMP array files in the same directory since the program would not know
which one the index file DIR01.VNX should be associated with.
VIEWING GIF89A FILES - Special Case:
If you are viewing a single GIF89A file, most of the 89A extensions will be
processed including multiple images, plain text and control blocks. Comments
will not be displayed. Because of the way VESAVIEW reads images into
Extended memory before displaying them, the plain text will only be displayed
on the screen (not XMEM). This will prevent the printing of the text since
printing is done from what is in Extended memory. One way around this, if
your screen has enough resolution to display the entire file, is to save your
screen out to another file with <G> and then pull up that file and print it.
NOTE, that the save commands will only save out what is on the screen after
all of the 89A extensions are processed. If the extensions include delays
between images, or require the user to <press> a key, the program will
continue after 15 seconds maximum so that slide shows will not be put in a
wait state looking for user input.
If you are viewing arrays which include GIF89A files, the extensions will be
processed entirely in XMEM before displaying them in the array. No text
extensions will be displayed (they would probably be too small to read
anyway). Delays between GIF89A extensions are not processed when displaying
array images for increased speed.
VIEWING HPG or PLT FILES:
To view a plot file created in a HPGL format, move the cursor to the filename
and press <ENTER>. Then choose the Display Mode and Plot Mode you wish to
use. The program will try and determine the size of plot from the plot file
header, but some CADD packages don't supply this info in which case the
program will assume a "C size". The HPGL codes for Plot Sizes are:
PS4 = 'A' size
PS0 = 'B' size
PS1 = 'C' size
Choosing a display mode of FIT, 2X or 4X will speed up the drawing process
but the resolution of the image will be diminished. As the image is decoded,
you will see it being drawn in a preview mode at screen size. After the
image is complete, pressing any key will swap you to the actual image as
stored in Extended memory for panning around in. Pressing <ESC> (or right
mouse button) as the image is being decoded will abort it.
Currently supported HPGL commands are: PU,PD,PA,PR,PS,IP,SC,SP, CI and AA
Even though the LB,SI,SR,DF,DI & DR commands are parsed and used to display
the image on the initial preview screen, they are not supported as the
drawing is being created in Extended memory. This won't usually pose a
problem since this program was designed to view HPGL files created by CADD
programs and most of those programs represent Text etc. as vector elements.
WARNING: Only plot files which were created as C size or smaller should be
viewed, since the program does no checking for elements which could be drawn
'off' the page if too big. This check was omitted to speed up the drawing.
DELETING FILES:
While the file list is displayed on your screen, you may delete a file by
moving the cursor to it and pressing <DEL> on the keyboard. To delete
multiple files, mark them with the <spacebar> (or right mouse button) and
then press <DEL>. You will be asked to confirm each deletion.
SEARCHING FILENAMES:
While the file list is displayed on your screen, you may select files by
searching their filenames for a specific string. Press <S> (or point to
SEARCH with mouse) and keyin the search string. The file will be selected if
it contains the exact string anywhere in its filename. Don't use the
wildcard characters * or ? since they will be search for literally.

While viewing IMG or HPGL files in a B & W mode:
P Send XMEM contents to printer as B&W image
I Create an IMG file (2 c) of entire XMEM contents. The 'I' option
may also be used if you are viewing an IMG or HPGL file in a color
VESA mode.
Z Create a PCX (2 c) file of entire XMEM contents.
In both Color and B & W modes you may pan screen with:
(make sure the NUMLOCK key is on to use keypad)
HOME Top left of image
END Bottom right of image
Page Up Move up approx. 1 inch
Page Dn Move down approx. 1 inch
ESC Return to File Selection Menu
The arrow keys on either numeric keypad or separate arrow keypad pan the
image approx. 1/4 inch in that direction. In addition, on the numeric keypad,
the 1,3,7 & 9 keys pan the image diagonally and the 5 pans to center of
image.
Use the Control key with left or right arrows to pan 1 inch to the left or
right.
SAVING SCREEN AS a BMP, GIF or PCX FILE:
While viewing an image in a VESA mode, pressing <B> will save the current
screen (not necessarily everything in Extended memory) to a BMP file with the
filename of your choosing. Pressing <G> will save to a GIF file. Pressing
<Z> will save to a PCX file. The dimensions will come from the mode you are
currently viewing the image in or the cropped size that you used. The color
table written to file will reflect any adjustments you've made with the
Function keys. When keying in the filename, if you don't include the period
or extension, the program will append the correct extension to your keyin.
If you keyin the extension with your filename, the program will use that
instead, but make sure you keyin the appropriate extension since the
extension is how the program determines the file type to display! You may
precede the filename with a Disk & Directory if you don't want to use the
current Disk/Dir.
SAVING SCREEN AS a JPG FILE:
JPEG is a standardized compression method for full-color (24 bit) and
grayscale images. JPEG is a lossy type of compression, meaning that the
output image is not necessarily identical to the input image. This software
implements JPEG baseline and extended-sequential compression processes and
the file format used is called JFIF. This format has been agreed to by a
number of major commercial JPEG vendors and probably will become the de facto
standard. Some commercial JPEG implementations are incompatible, especially
if they were written before the summer of 1991. Some other shareware JPEG
program's output will only work if they have the option of outputing as JFIF
standard files.
The procedure for saving the current screen to a JPG file is the same as for
saving to a GIF, BMP or PCX (see above section), except that an extra
question is asked after you key in the filename. You will need to enter a
JPEG quality factor ranging from 25 to 95. The default if you just press
<CR> is 75. A higher quality factor will result in larger files and less
loss of image quality. A lower quality factor will result in smaller files
with more loss of image quality.
It is not recommended to save array images as JPG files if they will be used
as graphic menus, since they will take considerably longer to decode.
CROPPING SCREEN & SAVING AS a BMP, GIF, JPG or PCX FILE:
If you press <C> you will be able to crop your screen image before saving as
a BMP, GIF, JPG or PCX file. You will see a box drawn around your screen
image when you first press <C>. Press a <T> to move the TopLeft corner of
box. Press <B> to move the BottomRight corner. Use the arrow keys to move a
single pixel at a time, or PageUp, <CTRL>Leftarrow or <CTRL>Rightarrow to
move 10 pixels at a time. <HOME> will move the Topleft corner of box to
Topleft of screen. <END> will move the Bottomright corner of box to
Bottomright of screen. <ESC> will abort and a <CR> will start the screen
save. You will be prompted whether to save as a BMP, GIF, JPG or PCX file.
See 'Using a Mouse' below.
SCALING XMEM CONTENTS TO SCREEN & SAVING:
If you press <S> you will be able to scale the entire image in XMEM to your
screen. You will see a box drawn around your screen when you first press
<S>. If you just press the <CR> key at this time, your entire image will be
fitted to your screen at the current VESA resolution. Use the arrow keys
etc. (like in cropping above) to move the lower right corner of box. Scaling
always occurs about the upper left corner of image, so you can't move this
point. <ESC> will abort and a <CR> will start the screen save. See 'Using
Mouse' below.
SAVING XMEM CONTENTS AS an IMG or PCX FILE:
While viewing a 2 color Black/White image (either IMG, 2-color PCX or HPGL
files), pressing an <I> will save the entire eXtended memory contents to a
IMG file, or pressing <Z> will save as a 2-color PCX file. You will have the
opportunity to reverse the image before saving. It doesn't matter whether
you are viewing the image in a color VESA mode or one of the Black & White
modes in order to with the <I> mode, as long as the original image was
actually a 2 color image. Currently, there is not a cropping option before
saving as a IMG file. However, if you are viewing the 2-color image in a
color VESA mode, you could save out as a cropped BMP, GIF, JPG or PCX file.
PRINTING IMAGES:
Before displaying an image that you will be printing, you should pull up the
Printer Setup Menu and Printer Model Menu (submenus of OPTS menu) and make
any necessary changes to model, style, size, margins, rotation and gamma etc.
After an image is displayed, any adjustments to color/brightness/contrast
will be reflected in your print. The gamma value (see description of /PGn
qualifier above) is a good tool to use if adjustment to brightness is needed
for printouts. The maximum size of image is limited only by the amount of
free XMEM you have. The maximum size of print is 10.5 x 8.0 inches on most
printers. On the DeskJet 550C printer, note that you can't print on the
bottom 1/2" of page, so if you are centering your print, the maximum length
can't be greater than 10.0", but if you set your Top Margin to the minimum of
0.05", you can squeeze in about 10.4".
If you want to print multiple images, select them from the file list with the
<Space Bar> (or right mouse button) as for slides, and then press <P> (or
point to PLOT with mouse). Each file will be displayed on screen and
automatically plotted until the last one is processed. NOTE that all of the
plots will use the same size, rotation, justification etc. from the plotting
options menu. Pressing <ESC> (or right mouse button) will abort the
plotting. NOTE: This option is only available in Registered Versions.
While a color image file is displayed on the screen, pressing <P> will create
a print on your active printer in the current print style. The fastest print
style is the halftoning process. The scatter style will produce a better
quality print in most cases, but will take longer to process. You may cancel
the plot by pressing <ESC> (or right mouse button) during the plot. The port
defaults to LPT1 unless you specified a command line argument of /P2 or /PF
when starting the program. The actual plot will be of your entire image
(stored in extended memory) and not just what you may be viewing on your
screen.
While viewing a 2-color (black & white) file or HPGL (.PLT or .HPG), pressing
<P> will create a Black & White print.
See description of /FB, /FW & /FN above to preserve image context when your
print is being scaled down from the original size. You can use any of the
printer qualifiers (available as command line qualifiers or from the Printer
Menu within program) to change the defaults for Printer Port, Printer Type,
Resolution, Rotation Angle, Width and Top & Left Margins.
If you select a Print Width greater than 8.5", the program will automatically
rotate print 90 degrees (unless 270 was already selected). The program will
beep if you try to use an invalid combination of size, rotation angle,
margins or resolution.
MOUSE USE:
In most cases where the keypad is used to move the text cursor, a MicroSoft
compatible mouse can also be used. You must install any required mouse
drivers before running VESAVIEW.
The Left button is used just like the <CR> key on the keyboard to display one
image. It is also used to select choices from pop-up menus, to select
commands at the bottom of screen and to select the PageUp and PageDown icons
from the vertical bar on the right side of screen.
The Right button is used just like the <ESC> key on the keyboard to abort
displays and menus. It is also used to mark files for use in arrays or for
displaying them as slides (like the <spacebar>).
If a large image has been displayed in one of the 256 color VESA modes,
holding down the Left mouse button will display a panning icon on your
screen. The green box represents your entire image size and the red box
represents your screen size. While holding down the Left button, move the
mouse and the red box will pan around with the green box. When you let go of
the button, the screen with be moved to reflect your new window area. This
mode of panning is much quicker than using the arrow keys, although you will
probably use the arrow keys for fine tuning the pan. If a double-beep is
heard when trying to use this feature, your image is probably smaller than
your screen and no panning is possible.
When Cropping an image, the Left mouse button will move the upper left corner
of the cropping box and the Right mouse button will move the lower right
corner of box. Pressing both the Left and Right buttons simultaneously will
start the save (like pressing <CR>). Scaling works the same except the Left
mouse button is not used (can't move the upper left corner of scaling box).
RUNNING Under WINDOWS 3.1:
VESAVIEW can be run in a Full Screen mode from Windows 3.1. Because of the
way Windows 3.1 allocates memory, it is suggested that you use a .PIF file
to run VESAVIEW. The following are recommended settings for the PIF file
when running under Windows:

CAUTIONS:
The array used to store the files in current directory is limited to 500
files. More files than this will just be truncated from directory listing.
The program determines the type of file to display by the extension used on
the filename. Supported extensions are BMP, GIF, IMG, JPG, PCX, TGA, TIF,
HPG and PLT. Any other extensions are ignored. Incorrect extensions may
cause program to hang (ie. Don't name a PCX file with a GIF extension).
Even though your VESA driver thinks it supports some of the higher resolution
modes, your hardware may not have the required memory to do so. Therefore,
you need to lockout these modes from the program with the /LOmode command
line switch. If you don't lock out these modes, the program may hang and
you'll have to do the 3 finger trick (<CTRL> <ALT> <DEL>).
When printing, make sure your printer is online before pressing the <P> key,
otherwise the printer may lose some of the data or lock up the program.
HINTS:
When creating arrays of images that include 24 bit files, you may want to
toggle the 24 bit palette option to STANDARD to speed up the processing. The
color detail will not be too apparent at this small scale.
To create and save a slide show sequence, just create an array image and save
it. The images on the array will be arranged in the order in which they were
selected originally. All you need to do to play the slide show is pull up
that array image, press 'M' to mark all files, and then press the left mouse
button to start the show. You should set the delay and fade before pulling
up the array if desired.
It is suggested that you prefix your array filenames with a 0 (zero) so that
they will be alphabetized at the beginning of the directory listing for
easier location. (Ex. 0DIR01.GIF, 0DIR02.GIF etc).
If you will be using your array images as graphic menus for file selection,
a lower resolution array image will update on the screen faster. Even if you
have just a few images to catalog, by placing them in a larger format array
image (ie. You have only 9 images to catalog but create a 6 x 6 array image),
the screen will be able to recall this array as a menu much faster than
creating it in a 3 x 3 array image. This is due to the greater compression
of large areas of blank space on the screen.
If you don't have a mouse, the graphic arrays you create can't be used
graphic menus. You will need to manually delete the .VNX file for the array
file so that the system will think the array file is just an ordinary image.
If you are using a printer supported by the DOS GRAPHICS command, you can get
a quick print of a Black & White screen by using the GRAPHICS command before
running VESAVIEW. Version 5.0 of DOS supports the DeskJet & LaserJets and
the syntax would be:
GRAPHICS DESKJET /r (the /r will reverse black & white)
Use <SHIFT><PRT SCRN> while graphics are on the screen to initiate the
print.
If you are printing to a color printer and you need to lighten up your print,
try increasing the Gamma value instead of the brightness. This will lighten
up the lower intensities and leave the higher intensities as they are.
Besides using the SCALE option, there is a trick you can use to scale down an
image by 1/2,1/3,1/4...1/9. Mark just one image and display it as an array.
Select the Array Size according to the scale factor you wish to use. (The
color table used to display a single image as an array will be the true color
table of that image and not the standard palette). After the image is
displayed, use the CROP feature to save the area you desire as a color image.
Note that when a single array image is displayed, the background color and
text colors will change according to the color table of the single image
being displayed.
If you need a VESA driver for your graphics card, login to Compuserve and go
to the IBMPRO forum (GO VESA). In Lib #12 (Vesa), you will find VESA drivers
for almost any card.
If you are not sure what graphics card you have in your machine, there is a
great little program in the GRAPHSUPPORT forum on Compuserve (GO PICS). In
Lib #14 (Misc Util & Code) download VDEOID.EXE. This program will try and
determine the card manufacturer & memory on it.

REVISION HISTORY:
v1.0 - v1.9 Developmental versions
v2.0 (4/03/92) First release to the Public as Shareware
v2.1 (4/10/92) Changed algorithm used for arrays color palette. Now uses
color dithering for much more accurate color reproduction.
v2.2 (4/21/92) Added new option to Automatically generate multiple pages of
array images and save them to GIF files without user
intervention. Also added a Scaling option.
v2.3 (4/27/92) Fixed a minor bug while displaying multiple pages of arrays.
v2.4 (6/05/92) Changed GIF decoder so that files which do not follow the
standard of setting byte 13 of header as a zero are decoded
anyway.
v2.5 (7/6/92) Added saving as PCX files (both 2 & 256 color). Added
cmd line qualifiers /FN, /FB & /FW so that scaling of B&W
images could retain more info of the original. Can now
read in Windows 3.X .BMP files (256 color). Added
ability to select files for display with a search string.
Added AA (absolute arc) & CI (circle) cmds to HPGL module
& fixed minor bug in display size.
v2.6 (7/16/92) Added decoding of TIF (2 color) files and fixed bug with
Filename Search option. Only decodes non-compressed and
run-length encoded TIFs.
v2.7 (10/9/92) Added decoding of 24 bit PCX & BMP files and decoding of 16,
24 & 32 bit TGA (Targa) files. Added ability to change
command line options from within the program from a menu.
v2.8(11/20/92) Added qualifier to disable beep after displaying images. Added
print enhancements: Color printing to HP PaintJet, PaintJet
XL, PaintJet XL300, DeskJet 500C & DeskJet 550C. REGISTERED
VERSION ONLY: Added ability to select plot size, rotation
angle, resolution, gamma correction and page placement. Data
can now be compressed before sending to printer to reduce size
and speedup printing.
V2.9 (12/9/92) Added qualifier (/COD) to optimize color palette and dither
the image when 16, 24 or 32 bit bit images are read in. Fixed
a bug which wouldn't allow an array of images to be saved as
a GIF file if no GIF file was displayed in the array.
V3.0(12/14/92) Added new B & W Scatter print style and Color Halftone print
style. Also added qualifiers for these styles (/PSBH, /PSBS,
/PSCH & /PSCS). Added /FTMn (fixed top margin).
V3.1 (1/11/93) Changed halftone printing pixels from 4 bits to 5 bits to
allow more shades. Added saving as a Windows BMP (256c).
Arrays can now be saved as either GIF, BMP or PCX files. The
screen is now erased around a cropped area before saving for
easier viewing.
V3.2 (1/22/93) Added support for 16 color PCX, BMP & GIF files. Added
support for 256 color (8 bit) TGA files. Saving of images or
arrays is now 3-4 times faster.
V3.3 (2/2/93) Added support for 16 and 256 color TIF files. Added
ability to use 320x200x256 & 640x480x2 modes without
requiring a VESA driver. These modes do not allow array
generation. Added panning with window icon for B&W
display modes. Added qualifiers /PXSn & /PYSn to allow
slight adjustment of X & Y scales when plotting HPGL & 2-
color files. Fixed bug where multiple image GIFs would
hang. Now, only the 1st image of these multi-image GIFs
is displayed.
V3.4 (2/9/93) Added support for GIF89A files by completely rewriting
the GIF decoder module. Multiple files can now be
selected for automated plotting (only available in
Registered Version). File directory is now sorted
vertically instead of horizontally for easier viewing.
Zooming (changing resolution) is now possible while
viewing in a VESA mode with the +- keys.
V3.5 (2/26/93) Fixed bug with vertical directory listing which caused
incorrect scrolling.
V3.6 (3/18/93) Added cmd qualifiers /UPSA, /UPSB & /UPSC so user could select
a default plot size if the .PLT file did not have an embedded
PS cmd to signify what plot size to use.
V3.7 (4/12/93) Added printer output to a file option (from menu or new /PF
qualifier). Added support for 24 TIF and 32 bit TGA files.
V4.0 (4/20/93) Images can now be graphically selected for display or printing
from previously created array images. These previously
created arrays images act as graphic directory menus. Also,
a help menu is now available while displaying graphics.
V4.1 (5/14/93) Program now checks for sufficient disk space before writing
out files. When keying in a filename, you don't have to
include the extension (ex: .GIF) anymore. If your keyin
doesn't contain a period, the appropriate extension will
automatically be appended to your keyin.
V4.2 (5/18/93) If you have enough XMEM, the first graphic array menu you
select will be stored in memory, so that returning to that
menu screen will be instantaneous instead of having to re-read
in the file on each return. This can be overridden with the
/NLAM qualifier. Added a new Printer Model submenu to the
Options Menu.
V4.3 (6/11/93) Added capability to put an array image and its index file on
a different disk/directory than its images are on. This
allows cataloging of images on a CDROM etc. Image sizes can
now be displayed on the images of an array if you use the
qualifier /AS (array sizes). Some changes in the way stack
memory was allocated were made to hopefully alleviate some
users memory restraint problems.
V4.4 (7/2/93) Added a fade in/out of images when displaying a slide
show. This is done with new qualifier /Fx or from
Options Menu. The order in which files are selected is
now used when displaying or creating arrays of them. The
sequence numbers are shown on the text directory listing.
A filename mask option has been added. The new qualifier
/Mxxx sets the mask to use. Enhanced error checking when
printing to prevent hangups when user input print sizes
& margins were invalid.
V4.5 (7/21/93) Added the reading and saving of 24 bit and grayscale JPEG
files (.JPG). Added a progress bar when reading in files from
the graphics menu to prevent boredom.
