VGACAP v8.0 Copyright 1987-91 Lawrence & Marvin Gozum, MD.

VGACAP captures MCGA/VGA 320x200x256 or SVGA 640x480x256/16, 800x600x256/16
1024x768x256/16 and 1280x1024x16 screens. VGACAP80.ZIP includes VGAFIL to
convert grabs to GIF, PCX, BMP (Windows 3.x) and TGA (Targa 16), as well as
hardcode VGACAP for FAST, SVGA SCREEN GRABS. As a generic conversion
utility virtually any viewable MCGA/VGA/SVGA image (320x200 to 1024x768) can
be converted to GIF, PCX, BMP, TIF or TGA format !

Update v8.0 * VESA support added. Grab screens to 1024x768x256.
Supports virtually ANY VESA-compliant SVGA card.

* VGAFIL v3.0

- Added TIF (TIFF P) encoding option.
- Configures for [Alt] or [Ctrl-Alt] hotkey mask.
- Added VESA detection/configuration of VGACAP.

* SVGA 1280x1024x16 grab routines added !

* Smarter bank detection! In some applications, grabbing
1024x768x16 screens resulted in only the lower half being
grabbed; banks are now verified and forced to bank 0,
if necessary, to avoid this problem.

* Faster 16-color grabs !

* Hotkey mask alternatives added. [Ctl-Alt] or [Alt] can
now be used as hotkey masks. You can configure VGACAP
to use either of them from VGAFIL. The [Ctl-Alt] is
particularly useful in applications that make
extensive use of the [Alt] mask (eg., WordPerfect).

* 100% BIOS grabs of 320x200x256 screens restored with BIOS
configuration. Particularly useful for users having grab
problems caused by the hardcoded VGA funtionality on their
motherboards.

* 320x200x256 grabs are now saved as RAW files for maximum
flexibility in encoding formats.

* 320x200x256 bloadable grabs (ie., *.BLD files) are now
optional via the old [F2] hotkey combination.


Update v7.7 * BUGFIX: Total overhaul of 1024x768x256 grab routines.

* BUGFIX: Trident bank switching code modified to force
64KB paging with single page mapping.

* VGAFIL v2.7 now encodes BMP files via a special color
reduction and remapping routine to virtually eliminate
"hotspots" when BMP images are remapped by Windows 3.x;
resulting in FASTER LOADS too !

* VGAFIL v2.7 cosmetic overhaul (similar to MVGAVU).

* VGAFIL v2.7 now incorporates faster PCX encoding.

* VGAFIL v2.7 BUGFIX: missing right column of pixels with odd
image PCX sizes; corrected.

* VGAFIL (v2.7) BUGFIX: "0" lenght PCX, BMP and TGA files
did not trigger the right error code (ie., unsupported
image dimensions); corrected.


Update v7.6 * BUGFIX: C&T 1024x768x16 and 1024x768x256 bank switching
code code got exchanged, thereby messing up each other;
corrected.

* BUGFIX: Video7 1024x768x16 and 1024x768x256 bank switching
code code got exchanged, thereby messing up each other;
corrected.

Update v7.5 * BUGFIX: Trident SVGA bank routines were still flawed
(we tried to accomodate the rare BR version of the
TVGA chip), resulting in erroneous bank switching;
corrected by restoring the standard 64KB TVGA 8800/8900
banking code.

* Added a new 'Trident' SVGA bank switching mode labelled
'Zymos'; this is essentially similar to Trident 8800/8900
chipset BUT with similar WRITE/READ bank switching
routines.

* VGAFIL (v2.5) customization menu updated to accomodate
'Zymos' setting.

* BUGFIX: Video7 1024x768x16 grabs required a different
bank switching routine; added 16-color bank switching code.

* BUGFIX: C&T 452/453 1024x768x16 grabs required a different
bank switching routine; added 16-color bank switching code.


Update v7.4 * Added FAST SVGA 1024x768x256 capture funtionality.

* Added FAST SVGA 1024x768x16 capture funtionality.

* Added FAST SVGA 800x600x16 capture funtionality.

* BUGFIX: SVGA C&T 452 and 453 bank routines were flawed;
corrected.

* VGAFIL (v2.4) now avoids sign-on screen if REGISTER.OVL
is detected and verified; saves you a keystroke.
