- WHAT IS VGACAP ?
-
- VGACAP is a resident utility that captures pictures in 320x200x256
- VGA/MCGA mode, any 640x480x256 SVGA mode or any 800x600x256 SVGA mode
- (e.g., AST, Dell, Genoa, Orchid, Paradise, Sigma, Tseng, Video7,
- 8514/A). VGACAP will capture and "Bsave" the 320x200x256 pictures of
- viewing/painting/graphics/CAD programs; SVGA 640x480x256 and 800x600x256
- pictures will be saved to a *.RAW file, which are "RAW" pixel dumps.
-
-
- WHAT IS RAW2GIF ?
-
- RAW2GIF is a *.RAW and *.PLT (PaLleTte) to GIF conversion program for use
- in a batch file (*.BAT) or as an interactive stand-alone program; *.RAW
- files are 640x480x256 or 800x600x256 screens captured with VGACAP (v5.0).
- RAW2GIF is designed to integrate itself with VGACAD v1.6 (and up); to
- convert BLD/PLT files to GIF, use BLD2GIF or VGACAD v1.50 (and up).

- REQUIREMENTS
-
- About 512KB of memory is required for RAW2GIF, although it uses about 2/3
- of that; it, also, requires that the BRUN41.exe runtime module be present
- in your present path; this is explained later in this manual. You MUST
- have a VGA or MCGA adaptor (at least BIOS compatible) present and an
- analog monitor to use VGACAP and BLD2GIF. VGACAP uses about 3KB of RAM.
- To use the 640x480x256 or 800x600x256 capture mode, you MUST have "Super
- VGA" (SVGA) or an 8514/A video card.
-
-
- HOW TO USE VGACAP
-
- Run VGACAP before entering your painting/CAD or digitized picture
- viewer. Press <ALT-F4>, while viewing your picture in any paint/CAD
- program and the screen and palette will be saved in your default drive
- and directory. If you are viewing your picture in MCGA/VGA 320x200x256
- then it will be "Bsaved". If you are NOT is MCGA/VGA 320x200x256 mode,
- then VGACAP will assume you are in 640x480x256 SVGA mode !
-
- <ALT-F4> is the new HOTKEY; this was done since VGACAP v4.0 is 100% BIOS
- COMPATIBLE; as such, it is as compatible as it can get AND SHOULD capture
- *ANY* 640x480x256 screen, regardless of the video card you are using.
- Users of VGACAP v2.0, if you are used to the FAST 320x200x256 grabs of
- VGACAP v2.0 (included), you can load both versions 2.0 and 4.0 without
- conflicting HOTKEYS (VGACAP v1.0 - v3.0 uses <ALT-F10>).
-
- The first time you run the program it will save your screen and palette
- to SCREEN00.BLD and SCREEN00.PLT respectively. If there is an existing
- SCREENxx.BLD or SCREENxx.PLT file, then it will increment to the next
- higher number. You can use your favorite memory managers to remove this
- TSR or reboot to release it from memory.
-
- If you are viewing in 640x480x256 SVGA mode or 800x600x256 SVGA mode,
- then the SCREENxx.BLD file is changed to SCREENxx.RAW; the "Bload" header
- is not included and a "RAW" contiguous pixel dump is implemented. If you
- wish, you can easily design your own utilities to read and process these
- "RAW" pixel dumps; they are simple contiguous pixel dumps with file sizes
- of 307,200 bytes (i.e., 640 x 480 = 307,200 pixels) for 640x480x256 SVGA
- mode and 480,000 bytes for 800x600x256 SVGA mode. The *.PLT files remain
- the same.
-
- Note: When in DOS or using a picture viewer (e.g., PICEM, VPIC, or
- CSHOW) or application which requires a keypress to continue, it
- is necessary to hit another key after hitting the 'HOTKEY'.
-
-
- LOADING PICTURES INTO RAW2GIF
-
- If you simple type "RAW2GIF <ret>", then you can select any filename by
- moving a highlighted bar (with the arrow keys) and pressing the <return>
- key. Pressing <Spc> allows you to select a different PATH, while <Esc>
- exits. Be sure *.RAW files have a corresponding *.PLT file or a error
- message will result. A *.GIF file is created with the corresponding
- name. GIF FILES WITH THE SAME NAME WILL BE OVERWRITTEN !
-
-
-
-
-
-
-
-
-
-
-
- PATHs MUST end with a backslash character "\" or your specified PATH will
- be rejected (an error beep will result). The following are legal PATH
- examples:
-
- "A:\"
- "B:\"
- "C:\GIF\"
- "D:\GIF\VGA\LARGE\"
-
-
- COMMAND LINE AND BATCH FILES
-
- RAW2GIF can be used in a batch (*.BAT) file for multiple conversions.
- Simply type "RAW2GIF [filename] " with no extension (path optional) for
- every file you want to convert in your *.BAT file; you can also use this
- method if you want to convert a specific RAW/PLT file from DOS.
-
- Examples: RAW2GIF screen00
- RAW2GIF \capture\vga\screen99
-
- RAW2GIF will automatically search for the *.RAW and *.PLT file. If no
- picture is found or a *.RAW file is encountered with no matching *.PLT
- file, then an error will result; both the matching *.RAW and *.PLT files
- must be in the same drive/directory or default drive/directory.
-
-
- The Chained VGACAD Environment
-
- In VGACAP50.ZIP (or .ARC) file is a file called BRUN41.exe, which is a
- runtime module distributed under licence with Microsoft; it can be
- distributed and used ONLY in connection with this program. You can place
- it in any drive/directory as long as your PATH has access to it.
-
- VGACAD v1.6 and up integrates RAW2GIF; it is actually a module of VGACAD
- (v1.6 and up). The advantage of using the BRUN41.exe is an integrated
- system of utilities and "sub-programs". New releases will be modified to
- support the "chained environment", with VGACAD as the integrator. Only
- one copy of BRUN41.exe is required.
-
-
- USING SVGA SCREEN GRABS IN VGACAD (v1.6 and up)
-
- If you capture a 640x480x256 or 800x600x256 screen for direct editing in
- VGACAD then:
-
- (1) from the VSCRN Menu, create a blank 640x480 or 800x600 Virtual
- Screen (whichever corresponds to captured screen);
- (2) exit VGACAD and DO NOT DELETE the TEMP files;
- (3) overwrite TEMP.RAW and TEMP.PLT with the selected SCREENxx.RAW and
- SCREENxx.PLT files; for example, at DOS prompt type
-
- "COPY screen00.* temp.*" <ret>
-
- (4) run VGACAD and load TEMP.PLT at the Files Menu;
- (5) click the VSCRN box; at the VSCRN Menu, click iSCR vDSK then OK; you
- see the captured 640x480x256 or 800x600x256 image as the new Virtual
- Screen.

- Whats next ?
-
- SYNPCX is utility to convert dithered, monochrome .PCX (Zsoft) files to
- smooth grey shades. This utility is primarily designed to convert
- scanned (e.g., Logitech & DFI hand scanners) Black & White images, saved
- to a .PCX file, for use and image processing with VGACAD, redithering
- with GIFPUB, printing with GIFDOT, or EGA conversion with VGA2EGA.
-
- We are also, developing VGASHW (a 256-color presentation system), VGACBT
- (the PROGRAMMABLE Computer-Based Training counterpart of VGASHW) AND
- MANNEQUIN (what "Weird Science" tried to do in the movie it will do on
- the computer screen with potential applications for Advertising and
- Fashion Design, aside from creating your own artistic nudes).
-
- If you support maverick authors like us, we will continue to develop
- innovative products like nothing seen commercially - otherwise they will,
- as many (sigh!) good Shareware programs, simply "DIE" from lack of
- support ! Compare the cost/benefit ratio of our products with commercial
- products; we want to continue supporting and developing these products.
- Please support the User-Supported (Shareware) concept; you, and you
- alone, determine whether it will be worthwhile to continue developing.
