SQZGIF v3.0 (c) Copr. 1988-90 Lawrence & Marvin Gozum, MD

SQZGIF resizes small or LARGE GIF/PCX pics (up to 2KBx2KBx256) to variable
sizes (ie., 320x200x256 to 1024x768x256) AND adds the synergistic power and
functionality of EGA2VGA (to create/add up to 256 NEW COLORS) with GIF images
with less than 256 colors (ie., 2 to 128 colors) for:

        * image processing/editing in VGACAD
        * conversion to EGA in VGA2EGA
        * printing or desktop publishing with GIFPUB (integrates GIFDOT)
        * reconversion to a smaller or larges 256-color GIF/PCX files
          with VGAFIL (included)
        * bloading in BASIC or QuickBASIC (BLD & PLT files only)

SQZGIF also integrates functionality of an unreleased utility - MIXBLD,
to weave four 320x200x256 BLD/PLT images into ONE SVGA 640x400x256 file !
MIXBLD functionality facilitates the rendering of 'oversampled' 320x200x256
video image grabs (ie., 'ala CDs' but for video) for greater 'texture' and
resolution by integrating oversampled ODD and EVEN video vertical fields
(ie., to get close to a FULL frame) AND oversampled horizontal fields.

Update 3.0      * Integration of EGA2VGA color generation functionality
                  (now two programs in one stand-alone utility) for GIF
                  images with less than 256 colors (ie., 2 to 128); up to
                  256 NEW colors are generated.

                  - variable Matrix control (auto, 2x2 or 3x3)
                  - variable color matching threshold
                  - variable image sizing

                * MIXBLD functionality (previously unreleased utility) for
                  users with MCGA/VGA 320x200x256 video grabbers.

                  - create 'subliminal' special effects
                  - create SVGA 640x400x256 images from
                    your 320x200x256 video grabber
                  - create multi-textured SVGA 640x400x256 images
                    from palette-modified 320x200x256 images

                * 256-color PCX encoding functionality with VGAFIL utility.

                * SPARE files (with the same structure of TEMP files) are
                  used instead of TEMP files when SQZGIF is used with
                  VGACAD v2.0 and up (when released) to keep TEMP files
                  currently used in the VSCRN VGACAD environment.

                * TEMP files used by SQZGIF have been enhanced transparently
                  (ie., so as not to interfere with old utilities) to
                  accomodate color information.

                * Bugfix: Encoding USERSCRN files created on a destination
                  path different from the default path returned an error
                  "could not find USERSCRN support files"; this has been
                  fixed with duplicate support files on destination path.
           
                * Bugfix: The last pixel of a raster line interpolated colors
                  from the workspace buffer (resulting in an odd vertical
                  line appearing on the extreme right); this has been
                  corrected with accurate floating point calculations.

Update 2.1      * User-specified zooming or squeezed GIF & PCX pictures.

                * Choice of fast interpolation or color averaging methods.

                * Integration of SQZGIF v2.1 (and up) with VGACAD (2.0 and
                  up, when released) for immediate importing of user-
                  specified, 'squeezed' or 'zoomed', color-averaged or
                  interpolated screens.


Update 2.0:     * PCX (version 5) format included (to 2KBx2KBx256)

                * BUGFIX: (MAJOR) All SVGA processing used weird colors,
                  if 320x200x256 mode was not processed first.  This has
                  been corrected <whew> !

                * BUGFIX: (MAJOR) 800x600x256 and 1024x768x256 SVGA
                  processing modes 'choked' and gave inappropriate error
                  messages.  These have been fixed.

                * Bugfix: VDISK path did not change to next available
                  path; this has been corrected.

                * Bugfix: MVGASCRN.RAW & .PLT files were not automatically
                  deleted when processing was aborted; this has been fixed.

                * Feedback on alternative VDISK path selectd is displayed
                  to let the user know where the MVGASCRN (RAW & PLT) files
                  are being written.
