CompuShow 2000! is a program for viewing
graphics on IBM compatible computers. The instructions for using the program are a combination of PROGRAM DOCUMENTATION and HELP SCREENS. The PROGRAM DOCUMENTATION is under the Help/Documentation menu, and you can read it on the screen, print it on your printer or write it to a disk file. You access a HELP SCREEN by pressing F1 at any point where you want a brief explanation of whatever you're currently working on. Help screens explain the menu %

Viewing graphics
To view a graphic file, "select" it by moving the "focus" (the highlight bar) to it and pressing the spacebar or Enter key, or by double-clicking with the mouse left button.
There may not be any graphics files in the current directory, but you can move to a different directory by "selecting" a <dir>, or change the window to a different disk drive by pressing F2 (the "hot key" for File/Drive).
Using Help
What you're reading right now is a "Help screen". Press F5 or click the zoom icon
in the upper-right corner to Zoom it to full screen. When the text of any help screen extends beyond the window, you'll see a slider on the scroll bar at the right side and can scroll with the cursor arrows or by clicking on the scrollbar or dragging the slider with a mouse: z

You know that you've seen all of a help screen if there is no slider on the right scroll bar (it all fits on one screen) or if the slider has reached the bottom of the right scroll bar (you've reached the end of the help text). To see how this works, scroll through this text until you reach the end, which says "End of Using Help". T
Most Help screens have some highlighted items ("keywords") that lead to other screens. For example the two items below lead to the help index and to the screen describing the help menu. Use the tab key to move from one keyword to another, then press Enter to choose that item. Double-click a Help keyword to choose that item with a mouse.
Help
Index Help
Help screens generally (this one is an exception) have a keyword at the very top which takes you back to the previous screen, so as you select keywords to step down into more detailed help screens, you can also step back up to the top (the Help Index).
When you're finished with help, press ESCape or Alt+F3 or click on the close icon
in the upper-left corner to close the help window.

File
DOS Shell
Leave the program temporarily to perform a DOS command or run another program. 9
To return to this program, type EXIT at the DOS prompt.
File
Quit this program.
"different window"
You may Copy or Move files from one window to a second window. The second window must be open on a different drive or directory.
"current file(s)"
Copy, Move, Rename, and Erase use the focused (highlighted) file. These commands only work on files, not <dir> directories or <vol> the volume label. Also, if the focused file is tagged, all tagged files are processed.
"Valid Name" B
Valid file and directory names have to follow certain DOS rules: J
Names may contain letters and numbers and ONLY THESE special characters: !
_ ^ $ ~ ! # % & - { } ( ) @ ' `
(Therefore, they MUST NOT contain spaces, commas, etc.)
They can have one to eight characters in the "base name", and an optional period and up to three characters in the "extension". #
You can't use the reserved names: I
CLOCK$ CON AUX NUL
COM1 COM2 COM3 COM4
LPT1 LPT2 LPT3 PRN
A directory can't have duplicates. So, assuming you already have a file named "ABC.1": O
copying a file named "ABC.1" to that directory will REPLACE the existing file 8
an attempt to rename another file to "ABC.1" will fail 8
an attempt to make a directory named "ABC.1" will fail
Of course, you may have a file named "ABC.1" in any number of DIFFERENT directories, but it can't appear more than once in the same directory.
Select a different
window as the destination to Copy or Move the current
file(s).

Video driver
Move the highlight to the driver you want and select Okay.
To use the special capabilities of your video card which go beyond the standard (CGA, Hercules, EGA, MCGA, or VGA) modes that are built-in to the program, select the driver designed for your video card.
If you have a modern Super-VGA, the "VESA BIOS Extensions" driver is probably the best choice. For an older (pre-VESA) Super-VGA, use the identify
video function, if you don't know which driver to select. ^
To disable video driver modes which don't work on your system, use the video
modes function.

When you select "Print", you'll have an opportunity to specify margins. The default values for margins, width and height should work on any dot-matrix printer. Laser printers may not be able to print all the way to the edge of the paper, so you may need to adjust the margins, width and height to fit the available page size. (PRINT THIS DOCUMENT TO CHECK YOUR SETTINGS FOR MARGINS, WIDTH AND HEIGHT.)
If your printer has a "control panel" (or a utility program) which allows you to change character size and/or line spacing, you can specify margins so that the documentation will fit those printer settings. ^
^
+-------------|
| v
Top margin is the number of blank lines at the ^
top of each page. Keep in mind that most dot- |
matrix printers start printing almost an inch |
down from the top of the page with Top margin |
set to 0. |
<-+-> |
| Left margin is the number of blank characters to |
+--"indent" each line. A Left margin provides extra |
blank space for punching holes in the pages. |
|
Text width is the number of characters of text to |
print on each line: |
<---------------- Text width -------------------> |
|
Text height is the number of lines to print down ---+
the page. |
|
So, Left margin plus Text width must be less than |
or equal to the number of characters that your |
printer is set for, and Top margin plus Text |
height must be less than or equal to the number |
of lines that your printer can print per page. v
The "Print to" setting lets you print to a parallel printer port (LPT1, LPT2, or LPT3), to a serial printer port (COM1 or COM2) or to a disk file (in the same sub-directory as the program). If you're not sure, use LPT1.
What's New: Changes by Version, Last Minute Changes

Video overview
--------------
CompuShow 2000! knows what "class" of video adapter (CGA, Hercules, EGA, MCGA, or VGA) you have and therefore what graphics display modes are available. Also, if you have a VESA Super-VGA, it automatically selects that video driver. This means that you DON'T NEED TO DO ANYTHING SPECIAL in order to display graphics on ANY IBM COMPATIBLE graphics adapter and ALL MODERN SUPER-VGAS.
However, there are two situations that CompuShow 2000! can't know about unless you tell it; either that your video board has PROBLEMS with certain display modes, or that it has ADDITIONAL display modes that go beyond the capabilities of a "plain vanilla" board (but has no VESA BIOS). 7
A simple "test procedure"
-------------------------
In the instructions that follow, we talk about "testing" various video modes. Here's how to find out whether a particular mode works on your computer: !
Press F4 for Graphics Options.
Press "S" (as needed) to turn ON the mode select dialog.
Press "A" (as needed) to turn ON rescaling.
Select a graphic file, SPECIFY THE MODE THAT YOU WANT TO TEST, and "Okay" to display in that mode: e
If the text screen remains (perhaps just changing color) your video card doesn't work in that mode.
Of course, if the graphic appears, but your monitor loses sync (and the image "rolls" or "scrambles"), you also want to treat that as a failure. b
If only PART of the image appears, or it writes over itself, you probably have the wrong driver.
However, keep in mind that the display in any particular mode may not be the BEST QUALITY for that specific image, so a "grainy" or "jagged" display doesn't mean that the graphic mode DIDN'T WORK. 7
"Built-in" graphics modes
-------------------------
All "IBM standard" graphics displays, Hercules monochrome graphics, and two non-standard 256-color modes (which work on the PS/2 and register-compatible VGAs) are "built-in". #
Mode (width x height x colors) Cga PCjr Ega MCGA VGA
While you SHOULD NEVER HAVE TO USE IT, you can override the automatic video detection:
2SHOW /Ax
where x is H for Hercules, C for Cga, B for EGA with monochrome monitor, E for EGA, M for MCGA, or V for VGA. G
Enabling/Disabling built-in modes
---------------------------------
Use the "Video modes" function of the Setup menu (Alt-S, M) to enable or disable these built-in modes and features:
The non-standard 320x400x256 and 360x480x256 modes work on the PS/2 and all hardware-compatible VGAs, giving a "plain vanilla" VGA something approaching Super-VGA quality. However, laptops in particular (perhaps some others) may not be able to do one (or both) of these modes. e
PCjr graphics modes (320x200x16 and 640x200x4) are also available on a number of Tandy 1000 models. ~
Some (early non-IBM) EGA adapters could not do hardware panning. If your EGA graphics display is "scrambled", turn this off.
The program can set the color palette in MCGA/VGA 16 and 256 color modes either through the video BIOS or by programming the hardware directly. You may find that one technique is smoother (or quicker) than the other (check it by rotating the palette).
If you have a "Super-EGA", with a 640x480x16 mode, your owner's manual should indicate the "mode number" (you'll need to enter the DECIMAL mode number). 3
Extended Graphics Modes
-----------------------
In addition to the built-in display modes, CompuShow 2000! supports a wide-range of extended graphics adapters by means of over thirty special video drivers (which are listed, below). Of course, if your adapter doesn't go beyond the standard modes, then you DON'T NEED a video driver. 6
There are three functions on the Setup (Alt-S) menu:
Setup / Identify video
This function attempts to identify the type of Super-VGA installed in your computer and presents a list of possible matches (if it includes "VESA", that's PROBABLY the best choice). There's no way for it to detect the "early video adapters" (listed below), but if you have one of them, you undoubtedly know what type it is.
Setup / Video driver
Pick a video driver by moving the highlight bar and then selecting "Okay".
Test each video driver mode (letters K-Y) as described above. If NONE of them work, try another video driver (or just select "none").
There are a number of reasons why SOME modes might not work; they may require a different model adapter, or more video memory than you have installed on your card, or perhaps your monitor isn't capable of a particular resolution. Also note that some video cards (eg. some ATI) only support a resolution like 800x600 if you use their "setup" or "install" program to specify that your monitor is capable of that mode.
Setup / Video modes
Disable any video driver modes that don't work correctly.
Video Drivers
-------------
Drivers are listed alphabetically in four groups: N
"VESA BIOS Extensions" is the correct video driver for virtually all Super-VGAs manufactured after 1991. The Video Electronics Standards Association (VESA) is an industry organization and every major video board manufacturer belongs. They've established a standard so that software developers no longer have to 'scramble' to keep up with dozens of different ways of programming Super-VGA adapters from different manufacturers. The VBE are in the Video BIOS ROM chip on most high quality Super-VGA boards. (Some of the lower quality boards may require you to load the VBE as a TSR program, although hopefully this practice is dying out.) a
Our VESA video driver supports all 20 VESA Super-VGA graphics modes, in 16, 256, 32k, 64k, and 16m colors and resolutions ranging from 640x400 through 1280x1024. (CompuShow 2000! is limited to 15 video driver modes. While we have yet to find a board with over 15 VESA modes, a special selection routine is used to pick the 15 "best" modes in the VBE.) O
In the early days of VESA, some board manufacturers failed to support all the graphics display modes in their VBE. If your board's VBE doesn't support the modes that it should, contact the manufacturer for an upgrade. If you're having trouble with a Diamond (SpeedStar, Stealth, Viper, etc), see the note at the end of this document.
Early Oak VGAs had a serious BIOS bug (which was apparently corrected in later models). Attempting to use a video mode which wasn't available on a particular model would prevent the board from doing graphics again until the computer was re-booted. So if you find a mode that doesn't work (and disable it), you may have to re-boot the computer before you can use the other graphics modes.
[Available modes depend on the video adapter and DGIS interface]

Problems with Diamond VGAs
--------------------------
Unfortunately, we've had literally dozens (perhaps hundreds?) of calls and messages from people having trouble getting a Diamond VESA BIOS to work. For months, the Diamond tech support area on CompuServe has been "buzzing" with angry messages from frustrated Diamond customers! k
As of this writing (1/94) we've been contacted by Diamond tech support, and it sounds like they're FINALLY looking into their VESA BIOS bugs. While there's no way of knowing how long it may take them to fix the problems, it does appear that they're now working on them, so PLEASE CONTACT THE DIAMOND TECH SUPPORT people to see if they have a fix for your model. )
In the meantime, since Diamond's VESA BIOSes have had so many bugs, a couple of ShareWare replacements have proven to be the only answer for some Diamond models. One is specifically for the Diamond "Viper" model. It can be found as VPRVS*.ZIP in CompuServe's IBM hardware forum (GO IBMHW) in library 3. The other is a "universal" VESA BIOS (which supports 15-20 Super-VGA chipsets). It can be found as UVBE*.ZIP in the IBMPRO forum, library 12. We'll have a copy of each (which may not be as up-to-date as CompuServe) on the GraF/X BBS (602-282-9035).
Printing overview
-----------------
Printing of all graphics to a wide variety of printers is a feature of the enhanced/registered version of CompuShow 2000! (This standard/ShareWare version does not print graphics). y
The following is a list of the supported printers, along with a few questions and answers related to printing graphics. #
Printer Drivers
---------------
All printer drivers (except the IBM Compact Printer) support both a "fast" print mode and a "quality" mode. The fast print mode is designed to allow you to print full page graphics using only DOS memory. All drivers support printing in black and white and "negative" (black and white negated, which is good for any maps or charts which are basically white lines on a black background). Color printer drivers also print color graphics (in color). The drivers are listed in 2 groups: 4
In "LQ mode", the Canon BJC-600 uses a 24-pin color dot-matrix driver, fine-tuned for the Canon ink colors.
Canon BJC-600 (360 dpi)
A BJC-600 driver at the maximum 360 dpi.
Color 8 pin (EX-800)
A GENERIC 8 pin color driver for 24/216" graphics line spacing. Tested on a Star NX-1000 Rainbow and Citizen MSP-50. Similar to EX-800, LX-800, FX-86e, LX-86, LX-80.
Color 8 pin (JX-80)
A GENERIC 8 pin color driver for 20/180" graphics line spacing. Similar to JX-80, LQ-1500, ALPS ALQ200.
Color 24 pin (LQ-2550)
A GENERIC 24 pin color printer for 24/216" graphics line spacing. Similar to LQ-2550.

Printer Questions and Answers
-----------------------------
WHEN I PRINT IN QUALITY MODE, I ONLY GET A PARTIAL PAGE
You're out of (computer) memory. The program must expand, rescale and dither the entire image to 'virtual screen' memory (see the Help/About box) before it starts to print. If you don't have enough memory, the program prints as much of the image as possible, starting at the top. The following table shows the amount of (computer) memory required for each driver to print in each mode.
If you've only got 640k (or less) memory, you'll be limited to printing in fast mode. If you have more memory, but haven't allocated EMS or XMS, check your DOS manual for HIMEM.SYS, EMM386.SYS or similar extended/expanded memory managers. If you have both EMS and XMS, use the Setup/Memory function to control which type (and how much) is used. &
WHY DO SOME PICTURES PRINT SIDEWAYS?
Graphics that are 2 colors and are "taller" than they are "wide" are printed in 'portrait' orientation, at 8x10". Other graphics are printed in 'landscape' orientation, at 7.5x10" (the same 4:3 aspect ratio as the screen). s
THE LIGHTS ON MY HP LASER PRINTER BLINK FOR A FEW SECONDS AND THEN IT EJECTS A BLANK (OR PARTIALLY PRINTED) PAGE.
The printer may not have enough internal memory to store BOTH soft fonts and the graphics data. You need to remove soft fonts from printer memory to print graphics. With minimum memory installed, you may only be able to print at 75 dpi in Fast mode. '
PRINTING TO MY LASERJET IS VERY SLOW! n
If you're printing to a LaserJet, DeskJet, PaintJet, or any printer that prints ONE ROW OF DOTS AT A TIME, use EMS memory, not XMS! In Windows, create a PIF with XMS=0k and EMS=1280k. In DOS, use an EMM386.SYS statement in CONFIG.SYS (following HIMEM.SYS, if you have it). Note the following comparison of EMS vs. XMS times (in minutes and seconds) on a 386/SX-16. Z
24-pin 8-pin LaserJet 300dpi
1800x900 900x720 3000x2250
(ems) (xms) (ems) (xms) (ems) (xms)
expand: 0:09 0:09 0:09 0:09 0:09 0:09
dither: 2:53 2:53 1:12 1:12 11:30 11:30
print: 0:40 0:55 0:18 0:42 5:50 55:30 <--- !!!
So printing to a LaserJet at 300dpi takes FIFTY MINUTES LONGER WITH XMS memory than with EMS memory!

CompuShow 2000! is a program for viewing graphics on IBM compatible computers. The instructions for using the program are a combination of Help screens and program documentation. You access a help screen by pressing F1 at any point where you want a brief explanation of whatever you're currently working on. The program documentation is accessed (for reading on the screen or printing to your printer or a disk file) from the Help/Documentation menu: 8

Viewing a picture
-----------------
When you select a file (by left-double-clicking, or by moving the "focus" to the file with the arrow keys and pressing the spacebar or enter key), CompuShow 2000! examines it to determine whether it's a graphic file that can be displayed:
CompuServe GIF Dr. Halo TIFF
CompuServe RLE ColoRix/EGA paint GEM/Ventura IMG
MacPaint Targa JFIF (JPEG)
PC Paintbrush PCX IFF/ILBM/HAM
PC Paint PIC Windows BitMaP
If it's not one of these, an information box tells you so. Selecting a graphic file brings up the mode select dialog. The top line shows the type of file, the size and number of colors in the image.
All available graphics display modes are on radio buttons with the best mode selected. This "best mode" is based on the size and number of colors in the picture and what the program knows about the capabilities of your computer. If your video card has problems with some display modes, or has additional (Super-VGA, etc.) display capabilities, check the video documentation (VIDEO.DOC) for setup instructions. s
You can display any graphic in any mode, by selecting its radio button. Push the Okay button to show the picture.
You can turn off the mode select dialog so that the picture is displayed immediately when you select the file. Check [F4] Graphic Options (and the F1 Help screens) for this and other options. 5
Viewing several pictures
------------------------
When you select any one of a group of tagged files, they're displayed one after another, with a delay between images. If you've tagged files in several windows, selecting any tagged file shows all tagged files (in all windows). l
[F4] Graphic Options lets you set the time between images, "lock in" one display mode for all images, etc:
With the delay set to ZERO seconds, you can do any of the "During graphic display" functions listed below. ESCape or right-click interrupts the sequence, any other key or left-click moves ahead to the next image. The program goes through the list of tagged files one time.
With the delay set to 1-9 seconds, the images are displayed in a repeating loop, until you interrupt them by pressing a key or clicking the mouse. 1
During graphic display
----------------------
As the image is being displayed, press ESCape (or right-click) to interrupt. The partial image will remain on the screen; press ESCape (or click) to exit the graphic. ,
Images larger than the screen may be "panned", using the mouse or arrow keys, provided that you have enough "virtual screen" (computer memory) available as shown on the Help/About box. (Keep in mind that the image WON'T BE LARGER THAN THE SCREEN, IF RESCALING IS TURNED ON in [F4] Graphic options). C
Tab displays the file name, graphic size, and display resolution.
If the graphic is displayed in a 256-color Super-VGA (video driver) mode, press "Z" to "Zoom" the image to 320x200 (which you may pan around), and "Z" again to return to the original mode. '
Alt-N negates any monochrome display.
Adjust the colors of an image displayed in an MCGA, VGA, or "Super-VGA" 16 or 256 color mode. Alt-G displays a color image as grayscale. Alt-N negates a grayscale display. Alt-C returns to Color. Alt-R rotates the palette of a color, grayscale, or negated image. -
PgUp/PgDn brightens/darkens the image, and:
RED: decrease [F1] [F2] increase
GREEN: decrease [F3] [F4] increase
BLUE: decrease [F5] [F6] increase
Press Alt-F10 (hold down the Alt key and press [F10]) to save the adjusted color palette to disk. When you display the file again, the program automatically uses this saved palette (press [F9] to see the original color palette; [F10] to switch back to the saved color palette.) \
On an EGA, you can do a similar color adjustment for images displayed in modes 7, 9, or Z:
The sixteen EGA colors are numbered 0 to 9 and A to F (color zero is always the background). To select a color to adjust, type the color number (0..9 or A..F). That color will flash, so that you can see where it is and decide whether it should be adjusted. In addition to using F1..F6 to adjust red, green, and blue, you can "step through" all sixty-four EGA colors in color number sequence: .
COLOR NUMBER: decrease [F7] [F8] increase
CompuShow 2000! as a Windows Viewer
-----------------------------------
To set up CompuShow 2000! to view graphics from the Windows file manager. 1
1. In the file manager, select File-Associate.
2. For "Files with Extension" enter "GIF" (for example).
3. Select "Browse" and then the drive and directory
where you installed CompuShow 2000!.
4. Select 2SHWIN.BAT (and then Okay, two times).
Selecting a GIF file in the File Manager (with a double-click or the enter key) will immediately display it with CompuShow 2000!. You can similarly associate different graphics file extensions (JPG, PCX, BMP, etc) to be displayed. 3
CompuServe GIF Graphics
-----------------------
With the release of GIF version 89a (July '90) several exciting new features are supported: 4
Text may be included for display with the graphic. '
A "user input" request causes CompuShow 2000! to wait for you to press a key before continuing, to allow you time to read text, etc. To indicate that it's waiting for you, the program "ticks". Press ESCape or right-click to interrupt further processing; any other key or left-click to proceed. X
Delays between images may be used for animation or to allow time for you to read text. |
Transparency may be used to create non-rectangular images (or text characters) to appear "on top of" the underlying image. {
Images may appear which are "disposed of" by restoring to either the background color or the previous (underlying) image.
Comments may be included by the person creating the GIF. After you've viewed a GIF with comments, you're asked whether you want to read them. Press "Y" or left-click to read the comments; press 'N', ESCape, carriage return or right- click to skip comments.
As a rule of thumb, transparency and restore to previous functions in a 640x480x256 GIF will require either EMS/XMS memory or a 640k system, with no RAM resident programs loaded (TSRs, RAM disks, etc.), so that at least 530k of memory is available. If there isn't enough memory available, the transparent color will be displayed, and restore to previous will be handled as a restore to background.
See CATALOG.DOC for information about "CompuMake Tools" for converting your existing graphics images to GIF, including support for all features of the GIF89a format. -
Command-line options
--------------------
When you start CompuShow 2000!, it automatically opens a window on the same drive and directory as the focused (top) window from last time (except for windows on drive A: or B:). You can tell it to open up to nine windows on the command line (note that "2SHOW ." opens a window on the current drive and directory): D
Display a single file and wait for a key-press or mouse click: 6
2SHOW /W HELLO.GIF or
2SHOW /V HELLO.GIF
In general, /V displays one file after another with the delay in seconds (as specified in [F4] Graphic Options) between images and is interrupted by any key or mouse click. The /W mode displays each file and accepts the keyboard commands described in "During graphic display", so you can zoom, pan, grayscale, negate, etc. Enter or left-click moves you to the next file and ESCape or right-click quits. /V works exactly like /W if you specify only one file, or if the delay is set to zero seconds. B
Display a single file, and eXit to DOS with the image on screen: "
2SHOW /X C:\PICS\FLOWER.PCX
Although it's not really a command line control, if you have an older color adapter such as a CGA with a monochrome monitor, and find it hard to read the screen, execute the DOS command "MODE BW80" before starting the program (put "MODE BW80" in your AUTOEXEC.BAT file.) When started in BW80 mode, CompuShow 2000! uses a special monochrome color set: black, gray, and white. (The enhanced/registered CompuShow 2000! allows you to select whatever colors you want for all areas of the screen.) /
A scripted slide show
---------------------
The enhanced/registered version of CompuShow 2000! allows you to create slide show scripts to automatically show graphics from any drive and directory, using the best display mode or a specified mode, with control of (up, down, left, right) panning, to run continuously or quit after one pass. You can set up "unattended" shows, specifying a delay in seconds between images, and even rotate the palette for dramatic fractal shows. You can also set up scripts for operator-attended shows, so that it waits for a keypress before moving ahead to the next image, and can even back up to previous images. '
Printing graphics
-----------------
The enhanced/registered version also prints all graphics on a wide range of printers. See the printer documentation (PRINTER.DOC) for a list of supported printers and related information. ?
Uploading to a Bulletin Board
-----------------------------
We encourage you to copy and share the Standard/ShareWare version of CompuShow 2000! with others. 2SHOW105.ZIP should contain FILE_ID.DIZ and the self-installing program 2SHOWA.EXE. O
BBS SysOps and ShareWare Distributors
-------------------------------------

You'll receive the latest complete standard version of CompuShow 2000! by mail as new versions are released. 7
Viruses and Trojan Horses
-------------------------
Due to the growing concern over computer viruses, Trojan horses, and other malicious programs, BBS SysOps and ShareWare distributors have started establishing "direct from author" libraries. We feel this is an excellent policy, and expect to see it become more common as time passes.
(Just to put in one last "plug"), your concern about possible "virus infection" is another reason to register the ShareWare that you intend to continue using. F

WHAT'S YOUR POLICY ON UPGRADES FOR REGISTERED USERS? {
As we release new versions of CompuShow 2000!, registered users are notified by mail, and may upgrade for a nominal cost. L
I JUST SAW A NEW VERSION ON A BBS, BUT HAVEN'T RECEIVED AN UPGRADE NOTICE! )
New releases of CompuShow sometimes seem to travel at the speed of light. Our first step is to post a new release on CompuServe, GEnie and the GraF/X BBS and then mail copies to our list of BBS SysOps and ShareWare distributors. It may take a couple of weeks to mail notices to registered users.
Keep in mind that "minor revisions" (like version 1.01 compared to 1.00) have small changes that don't justify a mailing to all registered users. If you want to upgrade to the latest "minor revision", contact me for costs.
Finally, keep in mind that you may have found a COUNTERFEIT! (See WHATSNEW.DOC for more information about hacked versions of CompuShow.) /
CompuShow and Windows
---------------------
I'M HAVING PROBLEMS USING COMPUSHOW IN WINDOWS
We've had some (limited) success making Windows work. In general it seems that some Windows drivers don't like DOS applications to do graphics, however sometimes these will make a difference: !
Make a "PIF" file for CompuShow =
Run Windows in standard mode, rather than 386 enhanced mode
Put FILES=60 in CONFIG.SYS 7
If CONFIG.SYS has EMM386.SYS add "D=48" to that line. ;
Unrecognized Graphics Files
---------------------------
I DOWNLOADED A GIF FROM A BBS, BUT COMPUSHOW SAYS IT'S NOT A GIF
It was probably uploaded by someone with an Apple computer, and has the infamous 128 byte "MacBinary header". A legitimate GIF file starts with "GIF87a" (or "GIF89a") in the first six bytes, so this "header" which some Apple software tacks on the front end of the file, actually creates a corrupt GIF. If the BBS SysOp doesn't have a program for stripping the header, we have one (UNMAC*.*) on the GraF/X BBS, and CompuServe, GO GRAPHSUP, LIBrary 14. E
I KNOW I'VE GOT A LEGITIMATE GRAPHIC IMAGE, BUT IT'S NOT RECOGNIZED K
Some programs which claim to produce a standard graphic file, may not conform to the official specification. If you find examples that CompuShow can't handle, we'd appreciate a copy of the file, so that we can add support for the format. However, some compression schemes (such as RIX) are confidential, so we can't support them. 7
WHY CAN'T I DISPLAY "JPEG" FILES CREATED BY "GIF2JPG"
Here's a quote from the Independent JPEG Group, under the heading SOFTWARE THAT'S NO HELP AT ALL: "Handmade Software's shareware PC program GIF2JPG produces files that are totally incompatible with our programs. They use a proprietary format that is an amalgam of GIF and JPEG representations. However, you can force GIF2JPG to produce compatible files with its -j switch, and their decompression program JPG2GIF can read our files (at least ones produced with our default option settings)."
GIF files
---------
WHERE DO GIF FILES COME FROM?
WHERE CAN I FIND A DESCRIPTION OF THE GIF FILE FORMAT?
WHERE CAN I GET MORE GIF GRAPHICS?
HOW CAN I CREATE A GIF FROM A PHOTOGRAPH?
The GIF (Graphics Interchange Format), pronounced "JIF", was designed by CompuServe and the official specification released in June of 1987. Since that time, it has become very popular, due to several factors. -
First, GIF uses an efficient compression routine which makes graphics files significantly smaller than in virtually any other format. Secondly, by design, it's an INTERCHANGE format. Graphics may be created by paint programs, fractal generating programs, on scanners or video capture boards. The originating computer might be an IBM, Apple, Color MAC, Amiga, or virtually any type of computer. Since most computers with graphics capabilities have (at least one) GIF display program, the graphics can easily be "moved" from one type of computer to another.
As GIF was created by CompuServe, the Graphics Support forum (GRAPHSUP) is the place to find complete, accurate, and up-to-date information about GIF. If you're not a CompuServe subscriber, but are seriously interested in trying graphics programming, I do recommend subscribing (call 1-800-848-8199, operator 229, to sign up or to verify current costs. As of 4/91 it's $39.95 for a "start-up" subscription which includes a hard-bound user's guide, a subscription to the CompuServe Magazine, and $25 credit toward connect time. Their connect rates (as of Feb '93) are 300 baud $6.00/hour, 1200,2400 baud $8.00/hour and 9600,14400 baud $16.00/hour. l
We've had a number of requests for "disks full of GIFs" or other graphics files. While CompuShow has been included on ShareWare disks with GIFs of various descriptions, these disks did not come from Canyon State Systems. We don't sell or distribute GIFs or other graphics files, with the exception of a few samples that are included on the enhanced program disk.
The best place to look for GIF images is CompuServe; "GO GRAPHICS" for a menu of graphics forums, containing literally thousands of images and related files. GIF images are also beginning to appear in significant numbers on other commercial services and a number of BBS's. v

CompuMake Tools
---------------
In response to a number of requests for a graphics conversion utility, we've assembled "CompuMake Tools", a set of programs to convert raster graphics images to GIF, supporting all features of GIF versions "87a" and "89a".
A hard disk is REQUIRED. CompuMake Tools manipulates images on the hard disk, so that the amount of computer memory doesn't limit the size of the graphic you can work with.
A graphics adapter is NOT REQUIRED for conversions, although an MCGA or VGA is recommended for functions that involve selecting specific colors for text, frames, background, etc.
Convert FROM:
CompuServe GIF Ega Paint
CompuServe RLE ColoRIX
MacPaint IFF/ILBM/HAM
PC Paintbrush Targa
PC Paint Microsoft Windows Paint (BMP)
Dr. Halo TIFF
GEM/Ventura IMG
Convert directly TO single-image GIF graphics (or BMP).
The image may be automatically "trimmed", removing solid color borders encoded as part of the image, or you can bypass trimming. Any size graphic may be rotated 90, 180, or 270 degrees. Output in either interlaced or non-interlaced GIF format. The global color map may be sorted with the most used colors first. Convert to 16 or 64 level grayscale. Add single or multiple "frames" around the image. Create multiple-image GIF graphics.
A major design feature is a direct interface with "PicLab", a Public Domain program included with CompuMake Tools. CompuMake works with PicLab to create multiple graphics images with a single color map and combine them into a multiple-image GIF graphic. 5
Incorporate any or all features of GIF version 89a. z
Delays and user input.
Transparency.
Restore to background.
Restore to previous image.
Plain text.
Comments.
With a "toolbox" concept in mind, CompuMake Tools accept file names and other parameters "on the command line", to allow you to use them in batch files, which have three definite advantages.
Since manipulating and combining graphics can take quite a while (even on a fast 486), you can start a batch file "job" and go get a cup of coffee.
If you want to "fine tune" the graphic you've created, you can make changes to the batch file and rerun it from the beginning, or even pick it up from a mid- point. w
Batch files you've already used can be "models" for similar tasks, making the new project that much easier to set up.
A tutorial with sample graphics and batch files are included to illustrate a number of graphics conversions including a full-blown multiple image GIF89a. +
CompuMake Tools is now available for $28.
CompuShow
---------
The original CompuShow continues to provide all the graphics display capabilities that have made it the "world standard" for IBM compatible computers since its release in 1987.
Its more "traditional" user interface features pop-up windows and a single directory screen. While it lacks the desktop design, multiple/moveable windows and pull-down menus of CompuShow 2000!, it displays the same graphic file types and shares support for all IBM-standard display modes on CGA, PCjr, EGA, MCGA and VGA adapters as well as Hercules and the full range of Super-VGA (etc.) video drivers. The registered version also supports printing to the same printers and has a scripted slide show capability.

Basic instructions overview
---------------------------
This document illustrates the many ways you can perform actions with the keyboard or a mouse. If you're familiar with modern PC software, you should have no trouble using CompuShow 2000! However, whether you're a novice or power user, you may find examples here describing terms and techniques that are new to you:
SELECTING items CHECK BOXES
the MENU RADIO BUTTONS
HOT KEYS INPUT LINES
the STATUS BAR HISTORY window
FOCUSED items push BUTTONS
DRAGGING with a mouse DEFAULT button
DIALOG boxes DOUBLE-CLICKING a mouse
Directory windows
-----------------
The program automatically opens one directory window, which shows what's on your computer; a listing of the files on your disk.
To display an image, SELECT the file by DOUBLE-CLICKING (click twice, quickly) with the LEFT mouse button or move the "FOCUS" (the highlight bar) to it with the arrow keys and press the spacebar or enter key.
TAG a file by DOUBLE-CLICKING with the RIGHT mouse button or press the "+" key. A checkmark following the file name indicates that it's tagged. (A second right-double-click or "+" key untags it.) SELECTing a tagged file displays all tagged files in all open windows.
Sometimes beginners think that CompuShow 2000! has "pictures inside it", and ask how they "import" more pictures, or get "other CompuShows" that have different pictures. Just remember that CompuShow 2000! is the PROGRAM (the "computer tool") that displays pictures, and the pictures are actually graphics FILES ON YOUR DISK(S). Wherever the files are located on your disk(s) you can move around, find and display them. O
File/Drive [F2] lets you switch the current window to a different disk drive. O
File/New window [F3] lets you open additional windows, up to a total of nine!
Selecting a directory <dir> moves you into that directory. Keep in mind that DOS uses "." to mean THIS directory, and ".." to mean the directory ABOVE THIS ONE. b
If the disk has a volume label <vol> selecting it jumps immediately to the root (top) directory. I
The menu, hot keys, and status bar
----------------------------------
The pull-down MENU (across the top of the screen) contains entries for all the things you can do in the program. Many of these operations have HOT KEYS assigned to them. For example, in the File menu, you'll find "New window F3", so pressing the F3 hot key is a short-cut to open a new window. h
Some of the menu commands only work when you have MORE THAN ONE DIRECTORY WINDOW OPEN. Specifically, File-Copy, File-Move, Window-Previous, Window-Next, and Window-List are disabled ("greyed out") when you have ONLY ONE WINDOW OPEN. Also, the "hot-keys" for these commands and dragging files with a mouse are disabled until you open at least a second window. g
The STATUS BAR (across the bottom of the screen) does two things. First, it shows some of the most used hot keys, both as a reminder and also so that you can click the hot key on the status bar to "push it" with a mouse. Secondly, as you move across the menu bar and pull down menus, the status bar shows a short description of the menu item that's focused. !
Using the menu
--------------
Here are examples of various ways to call up the Graphics Options dialog:
___With the keyboard___ 5
F4: press the hot key assigned to Graphics Options. `
Alt-O: Since the O in Options (on the menu bar) is highlighted, it's the hotkey for that menu.
F10: moves the focus to the menu bar. Then, either move across to Options with the arrow keys and press enter, or just press O.
After using Alt-O or F10 to pull down the Options menu, either move the focus with the arrow keys and press enter, or just press "G".
___With a mouse___ L
Click "F4 Graphics options" on the status bar at the bottom of the screen. s
Click "Options" on the menu bar at the top of the screen to pull down the Options menu, then click on "Graphics".
Move the mouse to "Options" on the menu bar, hold the left button down, pull the focus down to "Graphics" and release the button. (This press-move-release operation is known as DRAGGING with the mouse.)
Dialog boxes
------------
Some settings, presented as CHECKBOXES [X] may be turned on or off. Others appear as RADIO BUTTONS (.) and selecting one setting turns the others off (like the pushbuttons on a car radio). There are also INPUT LINES, where you type something, and these usually have a HISTORY of your previous entries. At the bottom of each dialog box are "Okay" and "Cancel" BUTTONS, with the color of "Okay" indicating that it's the DEFAULT.
___With the keyboard___ @
Move from section to section with the TAB key. Turn check boxes on or off with the spacebar. Change radio buttons with the arrow keys. Pull down the history for an input line with the down arrow key, scroll through the previous responses with the arrow keys and press enter. Press the default button by pressing enter. u
You can also change checkboxes and radio buttons and press Okay or Cancel buttons by typing the highlighted letter.
___With a mouse___ \
Change checkboxes, radio buttons, access history and push Okay or Cancel by left-clicking. /
Advanced "Good Stuff"
---------------------
CompuShow 2000! is also a tool for organizing your files. As an example, let's say you have GIF files (pictures) mixed in with other files that you downloaded from your local BBS in a directory named "C:\BBS", which is in the current window. G
1. Press [F3] (File/New window) to open another window (on drive C:). :
2. Select ".." (or <vol>) to move to the root directory. L
3. Pull down the File menu, select "make sub-directory", and enter "GIFS". )
4. Select "gifs <dir>" to move into it. `
You now have a new, empty C:\GIFS directory in window 2 and your C:\BBS directory in window 1. F
5. Switch back to window 1, by pressing Alt-1 or [F6] (Window/Next). e
6. Press [F7] (File/Tag) and enter "*.GIF" to tag all files in the current window which end in GIF.
7. Press Alt-M (File/Move) and select window 2 as the destination, or drag a TAGGED file with the RIGHT mouse button from window 1 to window 2. s
You've just moved all the GIF files from your "cluttered" BBS directory into a new directory of their own. Notice that using Alt-M (File/Move) or dragging with the right mouse button MOVES the files (they're now in C:\GIFS and have been erased from C:\BBS). Using Alt-C (File/Copy) or dragging with the left mouse button COPIES the files (you have them in both places).
