GIFPUB and GIFDOT convert any of the following listed below to a dithered
(modified, error-distributed Floyd-Steinberg matrix with "Stucki-like"
values) Black & White image.
1) ANY colored GIF picture (2KBx2KBx256);
2) ANY 256-color PCX (version 5) picture (to 2KBx2KBx256);
3) ANY VIEWABLE VGA/MCGA 320x200x256 picture captured with VGACAP;
4) ANY VIEWABLE SVGA 640x480x256 or 800x600x256 picture captured and
converted to TEMP files used by VGACAD (v1.6 and up);
5) ANY 16-color picture converted to any size with EGA2VGA;
6) ANY 256-color picture converted to any size with SQZGIF;
7) Colorized/converted MacPaint (READMACs) with MAC2GIF.
GIFPUB saves the output to a .PCX (ZSoft) file for First Publisher, Ventura
Publisher, Publisher's Paintbrush/PC Paintbrush+, Aldus PageMaker (if you
rename the .PCX file to .PCC and use its import facility), WordPerfect 5.0
(through GRAPHCNV to import the PCX output). GIFDOT the output to most Epson
and IBM compatible dot matrix printers (or laser printers with Epson FX-80
emulation).
NO VIDEO CARD IS NECESSARY. For interactive viewing/saving, GIFPUB and
GIFDOT support CGA (640x200), Herc (720x348), EGA (640x350), MCGA/VGA
(640x480), EEGA or SVGA (to 800x600). You can adjust the brightness and
contrast levels through Grey Scale Skewing, Histogram Contrast Stretching
and several Histogram-equalization algorithms (NEW!) - without a graphics
card.
GIFPUB and GIFDOT facilitate very fine grey shades to "appear" in various
sizes (ordered dithers do not), while maintaining the aspect ratio in ANY
video mode (including EEGA and SVGA). With GIFDOT, you can directly
integrate output in your desktop publishing documents since GIFDOT supports
variable "tabbing" of printed output. With the "Tiny setting", 8 images can
be placed on an 8"x11" document.
Both GIFPUB and GIFDOT (v2.0 and up) support virtual screens for SVGA
pictures up to 2KBx2KBx256 (EMM support will follow shortly)! All the
detail in SVGA pictures will be accurately reproduced in your dithered
images (e.g.,fine text along with the continuous grey image). By using the
VDISK path you can redirect the creation of virtual screen in RAM (i.e.,
RAMdisk) for FAST processing or another drive for dual floppy users.
Update 2.0 * Full utililization of SVGA images (to 2KBx2KBx256)
* PCX v5.0 support (to 2KBx2KBx256)
* Histogram-equalization; new image processing function
for global grey pixel redistribution
- Flat (linear)
- Sine (Pseudo-Gaussian)
- BiModal (Dual, Overlapping Sine Curves)
- TriModal (Triple, Overlapping Sine Curves)
- Lite Skew (linear w/ positive skew)
- Dark Skew (linear w/ negative skew)
* New error-distributed algorithm using modified Floyd-
Steinberg matrix with "Stucki" values
* User-definable dither density
* User-definable EEGA/SVGA video modes
* Enhanced Brightness and Contrast-Stretching algorithm;
precise grey scale adjustment; reorganized around
Histogram Analysis for better feedback and analysis
* Extended grey scale parsing algorithm - 256 greys mapped
instead of 64 for enhanced detail
* Fast 256-color palette read/write algorithm
* Bugfix: Selection of files with "**MORE**" corrected
NOTE: GIFDOT & GIFPUB will soon be combined as ONE program - GIFDTP - since
both programs use essentially the same algorithms and routines but
output to different devices.
