-
- Using CompuShow: A Quick Start Overview
- =======================================
-
- CompuShow is a program for viewing graphics on an IBM compatible computer.
- This section is designed to give you a brief overview and get you started
- quickly.
-
- A number of 'reminder prompts' appear at the bottom of the screen. For
- example, 'F1help' means press the [F1] function key for help. If you have a
- mouse, you can also left-click on any of these prompts. When we say 'F1help'
- or 'F2log', it means press the function key or left-click on the prompt.
-
- 1) Start the program from your DOS prompt by typing 'CSHOW' and a carriage
- return. The screen shows a sorted list of the disk files in the current
- directory. If you loaded CompuShow from a floppy disk, you can remove the
- disk to mount other floppies and use Alt-A or Alt-B to "log in" the new
- disk.
-
-
-
- [CSHOW.DOC] Page 1
- 2) The cursor is positioned in an "input area" near the bottom of the
- screen. Use the "up arrow" cursor key (or your mouse) to move up into the
- file directory.
-
- 3) Move the highlight bar around the list of files using the mouse or cursor
- arrow keys, PgDn, PgUp, Home, End, etc. (Click the mouse above the top
- line of file names to page up or at the bottom of the screen to page
- down.)
-
- 4) With the highlight bar positioned at a graphic file, press the spacebar
- (or click the left mouse button) to view the picture. If you don't know
- which files are graphics, just try each one in turn. CompuShow will tell
- you if a file isn't a graphic.
-
- 5) Press ESCape (or click a mouse button) to return to the file directory
- and you're back at step 3 ready to select another file, or...
-
- 6) Press ESCape (or click the mouse in the input area) to return the cursor
- to the input area (you're back at step 2).
-
- 7) Press ESCape (or right-click) in the input area to exit CompuShow and
- return to DOS.
-
- Of course, you may have graphics files on a different disk drive and/or in a
- different directory (and it's quite possible that there are no graphics files
- listed on the current directory screen). There are several ways to select a
- different directory:
-
- a) With the highlight bar at a directory (marked <DIR>), press carriage
- return (or click the mouse) to move into the directory.
-
- b) F2log to pop up the "log box" to switch to a different drive or one of
- the special sub-directories listed.
-
- c) Use Alt-A and Alt-B (hold down the 'Alt' key and type 'a' or 'b') to "log
- in" a new disk in floppy drive A: or B:
-
- Tagging Files
- -------------
-
- - Press F7 or click the space to the left of the file name to tag the file
- at the highlight bar. A "tag-pointer" appears and the highlight is moved
- down one file.
- - Press F7 or click a tagged file to un-tag it.
- - F9all to tag all files (on all screens of the current directory.)
- - F8show to show all tagged files.
- - As each image is displayed in turn, you may pan, adjust the appearance,
- etc., just as though you'd displayed it individually.
- - Alt-K to display the number of files in the current directory, bytes,
- total size in K-bytes and open space in K-bytes on the current disk drive.
- If files are tagged, the number, bytes and K-bytes for tagged files appear
- on a second line.
- - Alt-D to Delete file(s).
- - Alt-R to Rename file(s).
-
-
-
-
- [CSHOW.DOC] Page 2
- - Alt-C to Copy file(s).
- - Alt-M to Move file(s). Move only deletes if the copy was successful.
- If no files are tagged, Alt-D, Alt-R, Alt-C, and Alt-M work on the
- current file; the one at the highlight bar, and clicking on the prompt
- has no effect.
- - F10clr to clear all tags.
-
- Command-line file specification
- -------------------------------
-
- To start CompuShow logged to a different drive and/or directory:
-
- >cshow d: log to drive d:
- >cshow e:\pics log to drive e:, sub-directory \pics
-
- You can also specify a file mask:
-
- >cshow *.gif set the mask to *.GIF
- >cshow c:\graph\pix\*.pcx log to c:\graph\pix, set the mask to
- *.pcx
-
- CompuShow can display one or more files as specified on the command line:
-
- >cshow c:\pics\favorite.gif+ display one graphic
- >cshow d:\pics\*.gif+ display multiple graphics
-
- As each image is displayed in turn you may adjust the appearance, pan, etc.
-
- >cshow e:\graph\sample.pcx+x display and exit to DOS
-
- Add a '+X' to the end of the file name to display it and exit to DOS with the
- graphic still on screen.
-
- Changing options
- ================
-
- F3wide Switches between a two-column display of file name, size, date and
- time to a multi-column display of as many files as possible.
-
- F4mask Specify a file mask such as "*.GIF" or "*.*"
-
- F5sort Display only files or also show sub-directories. Sort ascending or
- descending on file name, extension, size, date, or unsorted.
-
- F6optn Turn on or off:
-
- - Quiet mode; whether or not the program makes sounds.
-
- - Gif Comments. Turn OFF to ignore any comments in GIF files.
-
- - Dithering is a technique for displaying an image with a large
- number of colors on a device with fewer colors. (If the display
- mode has as many or more colors than the image, the Dither setting
- has no affect.) Dither ON provides the best quality display,
- dither OFF is slightly faster.
-
-
-
- [CSHOW.DOC] Page 3
- - The Gamma1 setting affects display of true-color graphics in 256
- (dithered) or more colors. Some scanning and desktop publishing
- software work exclusively with "Gamma 1.0" images. Turn this
- option on so that the image is corrected for display on a PC
- monitor.
-
- Select one of the rescale settings:
-
- - Original size, no rescaling. An image may be smaller or larger
- than the screen. If it's larger and you have enough 'VScreen'
- memory (see SETUP.DOC), you can pan around the image with the
- cursor keys or mouse.
-
- - Rescale most images to fit the screen. The exception is monochrome
- (2 color) images. Frequently, these use intentionally randomized
- black and white dots and rescaling creates undesirable patterns.
-
- - Full-time rescales ALL images to fit the screen.
-
- The Graphics Information Box
- ============================
-
- If you type the name of a graphic file in the input area or position the
- highlight bar on a graphic file and press carriage return (or right-click),
- the Graphics Information Box pops up.
-
- CompuShow displays 'raster graphics' or 'bit-maps'. These graphics images are
- made up of rows of dots. The top line of the box identifies the type of
- graphic file, the width, height, and number of colors in the image.
-
- In the main body of the box are listed all the "standard" graphic display
- modes available on your computer, based on the type of video adapter(s)
- installed:
-
- Mode (width x height x colors) Herc Cga Ega MCGA VGA

- [CSHOW.DOC] Page 4
- You'll also see up to fifteen modes provided by a video driver that you've
- selected (see SETUP.DOC).
-
- You may display in any of the modes listed on the screen by pressing the key
- (or clicking) the mode you want. The "best available mode" (the mode used if
- you press the spacebar or left-click from the directory screen) is the
- character displayed at the cursor.
-
- The F6optn prompt in the lower-right corner allows you to control the display
- options without leaving the graphics information box.
-
- Press '0', carriage return, ESCape (or right-click) to return to the
- directory screen.
-
- During Graphics Display
- =======================
-
- As the image is being displayed, press ESCape (or right-click) to interrupt.
- The partial image will remain on the screen; press carriage return or ESCape
- (or click) to return to the information box or directory screen.
-
- - Images larger than the screen may be "panned", using the mouse or the up,
- down, left and right cursor arrow keys. Press a key (once) to pan in that
- direction. Panning will stop at the end of the image, or may be interrupted
- by pressing any key.
-
- Keep in mind that panning depends on the amount of memory available. (Check
- the size of 'VScreen' on the Shift-F1 information box).
-
- - TAB displays the file name and graphic size.
-
- - Alt-N negates any monochrome (or grayscale) display.
-
- - PgUp/PgDn adjusts the brightness of monochrome and color displays (unless
- they're dithered.)
-
- - On an EGA, adjust a color image displayed in mode 7, 9, or Z:
-
- The sixteen colors displayed 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. There are two methods for adjusting
- colors:
-
- - Increase or decrease the Red, Green, or Blue component:
-
- RED: decrease [F1] [F2] increase
- GREEN: decrease [F3] [F4] increase
- BLUE: decrease [F5] [F6] increase
-
- - "Step through" all sixty-four colors in color number sequence:
-
- COLOR NUMBER: decrease [F7] [F8] increase
-
-
-
-
-
- [CSHOW.DOC] Page 5
- Press Alt-F10 (hold down the Alt key and press [F10]) to save the adjusted
- palette to disk. When you display the GIF file in mode 7, 9, or Z, the
- program automatically uses this saved palette (press [F9] to see the
- original color palette; [F10] to switch back to the saved color palette.)
-
- - Adjust a color image displayed in an MCGA, VGA, or "Super-VGA" 16 or 256
- color mode (5, 6, 7, 8, 9, Z, S..Y):
-
- - The color may be adjusted:
-
- RED: decrease [F1] [F2] increase
- GREEN: decrease [F3] [F4] increase
- BLUE: decrease [F5] [F6] increase
-
- - PgUp/PgDn brightens/darkens the image.
-
- As with an EGA, the adjusted palette is saved to disk by pressing Alt-
- F10, and [F9] and [F10] allow you to review the differences between the
- original and the adjusted palette.
-
- - Press Alt-G to display a color image as <G>rayscale.
-
- - Press Alt-N to <N>egate a grayscale image.
-
- - Press PgUp/PgDn to lighten/darken the grayscale image.
-
- - Press Alt-C to return to a <C>olor display.
-
- - Alt-R <R>otates the palette of a color, grayscale, or negated image.
-
- CompuServe GIF Graphics
- -----------------------
-
- With the release of GIF version 89a (July '90) several exciting new features
- are supported:
-
- - Text may be included for display with the graphic.
-
- - A "user input" request causes CompuShow 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.
-
- - 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.
-
-
- [CSHOW.DOC] Page 6
- 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 to CompuShow. 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.

- share the standard version with others according to the following
- requirements:
-
- The standard version of CompuShow may be freely copied and shared
- with others, so long as no charge is made for the software, and it
- is unmodified and copied in its entirety, including all program
- documentation and all support files. It may be distributed via
- modem, provided that all files are transmitted (archived) together.
-
- Notice that ShareWare is copyrighted software. It's not "Public Domain"
- software, nor is it "free" software. If you continue to use this program
- beyond a reasonable "trial period", not to exceed 21 days, you must pay for it
- by registering.
-
- - Your registration fee makes it possible for us to continue to improve the
- program and to provide similar high quality software at reasonable
- prices.
-
- - IF YOU USE THE PROGRAM FOR COMMERCIAL PURPOSES, YOU MUST REGISTER.
-
- - For your $25 registration fee you receive the LATEST COMPLETE VERSION of
- the ENHANCED PROGRAM.
-
- - As a registered user, you'll be notified as new versions are released,
- and may upgrade for a nominal charge.
-
- Registering for the Enhanced Program
- ------------------------------------
-
- The enhanced program (CompuShow version 8.60b) includes all features of the
- standard program, plus:
-
- - Printing of all graphics images on most dot matrix and laser printers.
-
- See DRIVERS.DOC for a complete list of supported printers.
-
- - F8show tagged files allows you to specify an optional delay in seconds
- between images for a continuous "slide show".
-
- - Similarly, you may specify a delay for a one-pass or continuous "slide
- show" of the files specified on the command-line.
-
- - The scripted slide show feature follows a prepared script to provide
- automated display of graphics:
- - from any drive and sub-directory,
- - using the best (space bar) mode or a specified mode,
- - with control of (up, down, left, right) panning,
- - specifying an optional delay in seconds between images,
- - providing a "wait for a key press",
- - to run continuously or quit after one pass.
-
-
- [CSHOW.DOC] Page 8
- - A CompuShow Setup program, which lets you change screen colors, and
- specify "start-up" options, making the command-line switches unnecessary.
- You can also automatically log to a disk drive and/or sub-directory, and
- set the type of directory display you want.
-
- For your convenience, we've included an order form (ORDRFORM.DOC) with space
- for all the required information. (Complete it by hand or with a word
- processor.) Orders are shipped first class mail, and registration puts you on
- our mailing list for notification when future versions are available.
-
- Uploading to a Bulletin Board:
- -----------------------------
-
- We encourage you to copy and share CompuShow with others, but please be
- considerate when you upload to a BBS or give a copy to a friend. Be sure you
- include ALL FILES! This is A REQUIREMENT for distributing CompuShow as
- ShareWare, and if all files aren't present, CompuShow will display the
- "missing files" message, indicating that it MAY NOT BE DISTRIBUTED!
-
- BBS SysOps and ShareWare Distributors:
- -------------------------------------
-
- We appreciate the distribution of CompuShow on electronic bulletin boards and
- ShareWare disks. If you're a BBS SysOp or ShareWare distributor, contact me
- to receive the latest complete standard version of CompuShow and automatic
- free upgrades as new versions are released.
-
- 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.
-
- For your information, we post CompuShow to CompuServe (PICS, LIBrary 3),
- GEnie (IBMPC RT, LIBrary 14) and the "One Stop Bit BBS" (602-282-9035) and
- mail copies directly to a number of BBS SysOps and ShareWare distributors.
-
- (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.
