=============================================================================
Format:
vpic [[path\]filespec][/a][/e][/r][/c][/w][/?].
The default path is the current dir, and the default extension is GIF.
The /a option starts VPIC in Auto resolution select mode.
The /e option forces EGA mode, to use extended 16 color modes; see 5 below.
The /r option returns control to a calling program; see 4 below.
The /c option gives the current configuration; see 6 below.
The /w option wait for a keypress after each image in a multi_image file.
The /? option gives a help screen.
If filespec is a filename, the single file will be shown.
If path\filespec is a directory, a menu of all files meeting the filespec
int the path will appear.
Options and filespec may be entered in any order.
The options details are:
1. vpic [path\]filename[.ext] shows the file specified. The default path is the
current directory, and the default extension is GIF.
2. vpic [path\][filespec] to get a menu of all files in the specified path
meeting filespec (may contain wildcards). The default path is the current
directory, and the default filespec is any of the viewable files; just
entering 'vpic' will give a menu of all viewable files in the current
directory. Shows whether VGA or EGA and modes supported in upper left
corner. Path may not be . or .. since these would be interpreted as an
extension spec.
3. vpic /@[path\]slidefile[.ext] to do a slide show from commands in the
slidefile file. The default path is the current directory, and the default
extension is SLD. The commands are placed on seperate lines, and consist of
either a filename (GIF extension assumed) and optional display mode, or a
delay (viewing time) spec of the form d n where n is the desired viewing
time in seconds. The default viewing time is 5 seconds if no delay spec is
given, and the default viewing mode is whatever would look best. VPIC
understands comments preceded by a semicolon, blank or comment lines, and
extra spaces. For example, the following is file contents are understood by
VPIC, but not reccommended:
file1 1 ;First file in slideshow. Use mode 1.
file2.pcx ;This is a ZSoft filename with leading spaces
;This is a comment line with leading spaces, next is a blank line.
file3
d 15 ;Use 15 second delay. Has leading and separator spaces.
To end a slide show after the current picture, press any key. Escape ends
it immediately.
The mode requires a little further explanation. In the above slide file,
it says to use mode 1 with file1. Modes 1 thru 10 are the VGA (256 color)
modes, and modes 11 thru 20 are EGA (16 color) modes called out in the
configuration file. Most display boards only have a few of each type. The
Orchid Designer has 4 VGA modes and 4 EGA modes in the configuration file.
The VGA modes are 1. 320x200, 2. 640x350, 3. 640x480, 4. 800x600, and the
EGA modes are 11. 640x350, 12. 640x480, 13. 800x600, 14. 1024x768. Then,
the slide file says to show file1 in the 320x200x256 mode, and show all the
others in the default modes.
4. vpic /r shows the file and then returns to DOS (or a calling application
program) with the picture still on the screen in EGA/VGA. It is not
necessary to change video mode between viewing each file, but it is up to
the calling program to reset text mode (mode 3) after all viewing is done.
The /e and /a switches are valid in this mode.
5. vpic /e forces and EGA display with VGA to use extended EGA modes.
6. vpic /c prints the current configuration of vpic. You can configure vpic to
your display board using the VCONFIG program and a text configuration file
describing your board.
7. vpic /a starts VPIC in auto resolution mode.
8. vpic /? gives a help screen.
==============================================================================
CONFIGURING VPIC
To configure VPIC, enter
CVPIC [config_file]
where the default configuration file is VPIC.CFG, which is for the Orchid
Designer VGA board with white menu text color. Generally, you will answer
n to the 1st question and y to the 2nd question.
The default configuration of VPIC is for the Orchid Designer VGA card with
512K of display memory. If you have just EGA, you should use the EGA.CFG
file. If you have plain vanilla VGA (modes 10h, 12h, and 13h), use VGA.CFG.
The meaning of each field is given in display.brd, and the appropriate
portion of this file can be copied to a configuration file for most boards
using the Tseng, Paradise, Everex, ATI, or Video 7 VGA chip sets. Sample
configuration files are enclosed in this arc file for some of the more
popular boards, and can be modified for your board.
CONFIGURATION FILE - Characters after a ; are considered comments and ignored.
The first line is the board name, and will appear in the VPIC menu.
The 2nd line is the chip set, and should be TSENG, PARADISE, EVEREX, ATI,
C&T, VIDEO7, TRIDENT, or GENERIC presently.
The 3rd line is the number of 64K banks of display ram usable for 256 color
VGA pics (1 for standard VGA).
The 4th line is the menu text color; 0 thru 15 corresponds to black, blue,
green, aqua, red, violet, brown, white + 8 bright versions. For example
12 would be bright red text.
The following lines describe the modes supported by the board. Each field
is of the form F1 F2 AX BX CX DX W H C where:
F1 = VGA (256 color) mode flag.
F2 = 16/256 colors (as in mode 12h) flag.
AX,BX,CX,DX register values used to set this mode.
W, H, C are width, height, colors in this mode.
All the VGA (256 color) modes should be grouped first, followed by the EGA
(16 color) modes.
=============================================================================
Commands in menu mode:
1. The up, down, right, and left arrow keys move the cursor around the menu of
files.
PgDn/PgUp goto next/previous page.
Pressing a key goes to next file starting with this character.
2. Pressing the spacebar marks a file for viewing or slides, and moves to the
next file; it will also unmark a previously marked file.
3. Pressing enter will display the marked files in the order they were marked.
If no files were marked, pressing enter displays the file at the cursor.
4. Pressing F1 will bring up the help screen; any key will return to the menu.
5. Pressing F2 will do a slide show of marked files until a key is pressed.
6. Pressing F3 will display the file size and colors on the next to last line.
7. Pressing F4 will toggle between VGA and EGA modes.
8. Pressing F5/F6 will decrease/increase the default resolution for files
larger than 320x200 in VGA.
9. Pressing F7 goes to LOCK, which forces the default resolution (above)
no matter what the file size. Pressing F7 again goes to AUTO, which
automatically selects the resolution to display the picture. Pressing
F7 again goes back to to the normal mode.
10. Pressing F8 toggles the wait mode, where VPIC waits for a keypress between
multiple images.
11. F9 prompts for a new path/filespec, and displays a menu of the files in the
new path.
12. Alt X prompts if you want to delete the file at the cursor. Y deletes it.
13. Pressing ESCape ends the program and returns to DOS.
14. Pressing Ctrl Break (or Ctrl C) will get you directly to DOS.
All other keys are ignored. If errors are encountered, an error message appears
on the next to last line, and disappears when the cursor is moved. The menu
title is the search spec.
DECODING OTHER FILE FORMATS
The file decoding works in whatever mode you are presently using (VGA or
EGA) and at the resolution you are viewing with. This way, if you choose to save
to another file format, it will be in the same mode you are viewing with (EGA,
MCGA, VGA, or SuperVGA). The decoding is not as fast as could be done, but the
added versatility more than compensates for this. For example, EGA PCX files can
be very quickly decoded to EGA, but are in the wrong format for VGA, and
considerable manipulation is required to produce a VGA image. For all formats
except GIF, the method of viewing is to decode to a buffer for a single line at
1 byte/pixel, then copy this line to the display in whatever mode you are in.
This is a compromise for most file formats, since they are geared to EGA or VGA,
and display time suffers for the other mode, but it makes the code much simpler.
Besides, the other formats are supported mainly to allow easy conversion to GIF,
which is the preferred format for storage, since it gives the smallest file
size. This will also make EGA <-> VGA conversions possible, which is not
supported by most paint programs.
The TARGA viewing uses a fixed palette to speed up the decoding, so the
picture does not have what could be called good color. It is mainly there to
verify that an image is present. Use Image Tools TGAPIC to get an equivalent GIF
picture with excellent color rendition.
ADDED FEATURES
VPIC is meant to fill a void not covered by paint programs, and to allow
very convenient file viewing and conversion between file formats. It is not
meant to compete with the paint programs, and in general if a paint program does
something well (such as resize a picture to fill the screen or cut out a portion
of the picture), VPIC will not attempt to do it. On the other hand, if you think
of a feature which would enhance VPIC, please let me know, and I will consider
adding it to the program.
KNOWN PROBLEMS
1. The ATI 1024x768x16 mode uses 2 pixels/byte, unlike any other VGA or EGA
mode. It is not implemented at this time, and probably never will be because
it would require special cases in the various routines that make up VPIC.
==============================================================================
Commands while viewing a file (except in slide mode):
1. The up/down arrow keys will scroll the picture if longer than the screen.
The PgUp and PgDn keys will scroll by 10 lines. The Video 7 extended VGA
boards do not supported writing to non-displayed memory or scrolling pics
larger than the screen, so this function is disabled for these boards.
2. If pic is <= 1/2 the screen width, pressing 2 will give a double size image
(which may be scrollable) and pressing 1 will give the normal size again.
For VGA, the picture will be changed only in the horizontal direction; this
will unsquash some 320x400 pics so the aspect ratio is correct.
3. Pressing + will increase the resolution (320x200 to 640x480, etc).
4. Pressing - will decrease the resolution; useful if 800x600 rolls.
5. Pressing / or ? gives a help screen of commands available while viewing.
All the following conversion options check if the default filename is present,
and prompt for a new name if it is. They all now let you know what is happening
while the conversion proceeds. If you screw up at the new filename prompt, hit
Ctrl C to escape immediately to DOS; this will usually preserve a file you don't
want to write over. The safest bet is to view files on floppy, while running
VPIC from the hard disk. The new file is saved to the default drive, which is
the directory you run VPIC from.
5. Pressing Z will create a ZSoft (PC Paintbrush) file with the same filename
and extension PCX. The file will be in whatever mode you are currently
using (EGA or VGA). The VGA palette will be correct for the latest version
of PC Paintbrush, which saves a VGA palette in the file.
6. Pressing P will create a PC Paint or Pictor file with the same size as the
current screen. The default extension is .PIC, and for EGA it prompts for a
PC Paint or Pictor file.
7. Pressing G, I, M, U, <, or > will create a GIF file on the default drive,
and prompt for a new filename-the default extension is GIF. G is for
non-interlaced, and I is for interlaced, M is for mirror image, U is for
upside down (inverted), < is rotate image 90 degrees CCW, and > is rotate
image 90 degrees CW. The GIF file will be the same size as the current
image.
8. Pressing R will create a ColoRix file with the same filename and extension
SCx where x is a function of the screen size. If in EGA, will prompt if you
want an EGA Paint or ColoRix file.
9. Pressing T will create a Targa 16 file with the same filename and extension
TGA.
10. Pressing C will create a Dr. Halo CUT file with the same filename and
extension CUT. The pic will be the same size as the GIF file is currently
on the screen. A palette file will also be created.
11. Pressing A will 'animate' a picture by rotating the palette periodically.
This is especially effective on fractals, where large areas tend to be the
same color. Pressing spacebar will pause the palette rotation, and pressing
Enter will terminate it and return to the command mode. Thus, by waiting
for an especially nice pattern and then pressing Enter, the pattern can be
written to a file using the above file save commands. Pressing Esc will
return to the menu.
12. Pressing Alt X will prompt you to delete the current file. If you answer y
(yes), it will be deleted.
13. Pressing enter will return to menu or DOS, or show next file for marked
menu mode.
14. Pressing ESCape will end the display and return to the menu.
15. The following keys control the picture tone as follows:
F1 Decrease red content of picture.
F2 Increase red content of picture.
F3 Decrease green content of picture.
F4 Increase green content of picture.
F5 Decrease blue content of picture.
F6 Increase blue content of picture.
F7 Decrease contrast of picture (VGA only).
F8 Increase contrast of picture (VGA only).
F9 Decrease brightness of picture (VGA only).
F10 Increase brightness of picture (VGA only).
Alt-F10 Restore original palette after you thoroughly mess up the colors.
V Reverses the current palette (16/64 EGA only); interesting effect
especially for black & white images.
After a little experimenting, a 'washed out' VGA picture can be greatly
improved by using F1-F10 , and you can always start over by using Alt-F10.
To retain a black background in a VGA picture, the brightness should be
decreased when the contrast is decreased. If you have really improved the
picture, you can then save it to GIF by pressing G of I. VPIC will prompt
you if the file exists in the default directory, and you have the option of
overwriting it or giving a new filename. This works really well with images
created on the Howtec or Targa scanners.
All other keys are ignored. Pressing Ctrl Break (or Ctrl C) will go to DOS.
===============================================================================
IMPORTANT: Support for boards with other chip sets: VPIC will support other VGA
boards with extended VGA modes if the owners will write me with the details
of how to set the various modes, and how to bank switch the display memory.
Of course, if you also register VPIC I will give the problem more
consideration.
The bank switching Info for some of the 'not so common' VGA boards is
hard to come by, and is needed if VPIC is to support extended VGA modes for
these boards. A VGA board needs to bank switch for extended modes because
there is only a 64K window in the PC address space for graphics memory (from
A000 to AFFF), and extended modes require more than 64K of memory;
640x480x256 requires 307200 bytes of memory, or about 4.7 'banks of 64K'.
Bank switching is a means of mapping the (A000 to AFFF) graphics address
space into 64K chunks of actual display memory. Bank switching is a function
of the chip set used on the display board, and what I need is info on how to
switch banks and how to set the various modes the board supports. The use of
a display board would also help, since it will allow me to test the program
with that display board instead of 'programming blind'.

-------------------------------------------------------------------------
Revision history:
ver 1.1 1-13-88
Added test for EGA adapter.
Fixed menu colors.
Allow ESCape from marked file viewing.
Added Ctrl Break (or Ctrl C) exit to DOS anywhere.
Added 'disk full' notification when creating picture file.
Added critical error handler for 'drive not ready' errors.
ver 1.2 1-15-88
Changed name to vgif.
Slide mode now ignore the end of file mark in slide file, and any key
will now end slide mode.
Added slides to menu mode if S pressed-shows marked files as slides
until a key is pressed.
ver 1.3 1-21-88
Added better error checking to GIF file decoding. Notifies if bad GIF
file.
Fixed error reporting bug in single file mode.
ver 1.4 2-9-88
Added instantaneous screen update in slide mode from menu or command
(sld) file.
Added the /r option which allows an application program to call vgif
to view a file and then regain control.
ver 1.5 3-2-88
Added Page Up and Page Down keys to scroll by 10 lines at a time.
Added a max pic height of 819 lines so EGA buffer would not overflow.
Greatly improved color reproduction for 'problem' pictures (such as
FROG, ARCHIT, PUFFIN, VEGTABLE, etc). These pictures typically
have more than 16 colors. Selected colors on basis of frequency
of use where possible.
Fixed following bugs:
1. Line buffer would overflow into other variables if pic width
was > 640 pixels, causing strange results.
2. Didn't recognize the end of image marker correctly. This would
cause the palette to change when the image was done.
ver 1.6 3-11-88
Fixed a bug in handling multiple images. First noticed when viewing
WHIMMI.GIF.
Use same palette for multiple images, and get best color match.
Added L and S commands while viewing a picture. These allow you to
create full size paint program files.
ver 2.0 3-26-88
Added the ability to view long GIF files ( > 819 lines) without
wrapping the display.
Added the C and H (Dr. Halo) file creation option while viewing.
Added the L and S prefixes to paint program file creation commands
while viewing to save long pic files.
Added the Info and Help commands in menu mode.
Deleted the # requirement to specify a directory from the command
line. The program now looks for a directory which meets the
spec on the command line. If none is found, it assumes the spec
is for a single file.
Added F1 - F10, and V palette control keys while viewing a file.
ver 3.0 5-2-88
Added VGA capability, and support for Tseng extended VGA modes
(640x480x256 and 800x600x256).
Determines and displays available modes for your system.
ver 3.1 5-11-88
Fixed a bug in dir/file spec from command line. Now accepts
vgif d:\dir\*.gif or vgif d:*.gif, although the [\]*.gif is not
required, since this is the default filespec.
Fixed a bug in forced EGA when doing slides, where an interlaced pic
displayed at double size would have a 'venetian blind' effect.
Changed so pics larger than 320x200 are shown in 640x480 VGA; can get
800x600 by pressing + key.
Note that EGA mode on the Orchid VGA card appears squashed
vertically. This is normal, and cannot be corrected without
reprograming the parameters for mode 16, which would change
the vertical retrace frequency, and probably cause your monitor
to roll.
ver 3.2 5-26-88
Added 500 file menu, and assy language text screen updating; now
super fast.
Fixed a bug which caused the Vega VGA card to hang up.
ver 3.3 6-9-88
Added user spec of video mode for non-Orchid VGA boards.
Added GIF and Pictor save of current screen for VGA/EGA pics.
Added prompts to screen for conversion to other formats.
Removed conversion starting at first visible row-now does whole pic.
ver 3.4 6-23-88
Fixed a bug in the GIF save routine.
Added color, contrast, and brightness adjustment in VGA.
Fixed a bug in menu mode for marked files.
Added /n command line option to stay in 640x480x256 for VGA pics.
ver 3.5 7-14-88
Fixed some misc minor bugs.
Added increase/decrease resolution command while viewing 16 color VGA
pics (using the /e option).
Added slide mode for VGA.
Added lock mode option to start pics from the menu in a desired mode.
ver 3.6 8-8-88
Fixed some bugs.
Fixed EGA slide show.

Fixed CVPIC for ^Z as EOF char.
Fixed 16 color palette for other file formats if VGA 16 colors.
VPIC ver 1.3 2-2-89
Fixed cursor in menu.
Fixed 'lock up' if GIF header size wrong (640x350 labeled 350x640).
Now pauses pic if file error and waits for key press-can see partial
pics in bad files this way.
Shows GIFs with MAC headers (1st 128 bytes are not GIF standard);
if F3 (info) pressed shows if file has a MAC header.
Fixed so views and saves new ZSoft VGA PCX files which include
palette at end of file. Still doesn't load PAL files.
Fixed ZSoft file displays and saves.
Added Wait toggle (F8) which pauses between images in multi-image
GIFs, and allows conversion to other filetypes.
