LICENSING AGREEMENT
You may use this program for a 10 DAY TRIAL PERIOD. Should you find
this program useful, you MUST register it; you will then be provided
with the latest releases of the VGACAD system see last section of this
manual).
You can freely distribute UNMODIFIED copies of GIFDOT and charge $10
max for distribution, in lieu of recognized Users Group guidelines
(e.g., Asso. of Shareware Professionals or NY Amateur Computer Club).
WHAT IS GIFDOT ?
GIFDOT converts colored GIF/PCX pics (up to 2KBx2KBx256) or any of the
following listed below to a dithered (modified, error-distributed
Floyd-Steinberg matrix with "Stucki-like" values) Black & White image
and prints the output to most Epson and IBM compatible dot matrix
printers.
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 (version 1.6 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.
NO VIDEO CARD IS NECESSARY. Print images without viewing. For
interactive image processing, GIFDOT supports CGA (640x200), Hercules
(720x348), EGA (640x350), VGA (640x480), EEGA or SVGA (to 800x600,
1024x768 and up will be included in later releases). GIFDOT converts
colored pictures to 256 grey shades on a 64 grey scale continuum with
sophisticated Grey Scale image processing algorithms.
With error-distributed dithering, GIFDOT facilitates very fine grey
shades to "appear" in various sizes (ordered dithers do not); you can
integrate pictures in your desktop publishing output directly since
GIFDOT will allow positioning of an image anywhere on a document.
GIFDOT (v2.0 and up) supports 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., RAM
disk) for FAST processing or another drive for dual floppy users.
WHAT IS VGACAP ?
VGACAP is a terminate-stay-resident (TSR) utility that captures 256
color palettes and screens in MCGA/VGA 320x200x256, SVGA 640x480x256
and SVGA 800x600x256 modes. MCGA/VGA 320x200x256 images are saved in
"Bloadable" formats while SVGA images (*.RAW files) can be converted
to TEMP files thorough VGACAD for editing and use in GIFDOT.
REQUIREMENTS
NO VIDEO CARD REQUIRED FOR USING GIFDOT. About 512KB of memory is
required, although it uses about 3/4 of that. You MUST have MCGA/VGA
or SVGA to use VGACAP. VGACAP uses less than 2K of RAM.
COMPATIBILITY
GIFDOT has been tested on a 386sx clone, XT clone and PS/2 Model 50;
video modes were tested in CGA, Hercules, EGA, EEGA and SVGA video
modes using the STB VGA E/M 512, ATI VGA Wonder 512 card and IBM's VGA
PS/2 VGA card. Several users with IBM and Epson compatible printers
have yielded successful printouts with GIFDOT; laser printers with
FX80 emulation modes should also work very well.
486, 386, 386sx, 286 and AT users with extended memory should disable
"Shadow RAM". Although GIFDOT is predominantly coded in assembly and
C; QuickBasic (QB) 4.00b is used as a shell and error-handler. QB
v4.00b HATES Shadow RAM for some reason and locks-up (at least on our
386sx clone). With AMI BIOS, you can disable Shadow RAM by pressing
<DEL> during boot and changing the set-up; it is much wiser to have
EMM.SYS/QEMM.SYS or WHATEVER.SYS to manage expanded and extended RAM
anyway. With 2MB on board, I suggest you use 720KB for VDISK to
emulate a fast 3.5" drive and allocate the rest as expanded memory; a
1MB system with a 384KB RAMdisk (VDISK) would match 640x480x256
screens which decompress to 307200 bytes.
Users with third-party EMM.SYS drivers should avoid mapping the ROM
BIOS to "high" RAM (i.e., Shadow RAM) or mapping extended/expanded RAM
to areas where there is no RAM (e.g., to use LOADHI); QB's runtime
module crashes (at least on our 386sx clone). Keep two versions of
your CONFIG.SYS file; one with your usual set-up and one with a set-up
to run ALL our programs/utilities (preferably with as much VDISK as
possible). VGACAP cannot be loaded in "high" RAM.
If your system is still locks-up, do a 'naked boot' ! Rename your
AUTOEXEC.BAT and CONFIG.SYS files (e.g., to *.BAK) then reboot; this
way you can isolate the incompatible TSR or SYS file.
COMPATIBLE PRINTERS
GIFDOT was designed to run on Epson and IBM compatible printers that
support 120 dpi (horizontally) and 72 dpi (vertically) at the minimum.
Epson (e.g., LQ,FX,GX,RX,JX, ...)
IBM (e.g., Graphics Printer, Proprinter, ...)
The following partial list of manufacturers have compatible "ESC"
codes to run GIFDOT; if your printer supports "ESC L" (sets double
density graphics) and "ESC J" or "ESC A" (sets n/216 or 1/72 inch
single line spacing) GIFDOT will run on your system. Check your
printer manual.
Canon (e.g., PW series)
Centronics
C.Itoh
NEC (e.g., Pinwriter, ...)
Okidata (e.g., 92/93, 192/193, 292/293, ...)
Panasonic (e.g., 1080i,1090i, ...)
Star (e.g., Gemini, Micronics SG series)
Tandy DMP
YOU MUST DISABLE AUTO-LINEFEED; IF YOUR PRINTER HAS THIS FEATURE 'ON',
YOU MUST SET THE DIP SWITCHES TO TURN IT 'OFF' OTHERWISE YOUR PICTURE
WILL BE PRINTED WITH 'SKIPPED' LINES.
HOW TO USE VGACAP
Run VGACAP before entering your painting/CAD or digitized picture
viewer. Press <ALT-F4>, while viewing your picture. The first time
you run the program it will save SCREEN00.BLD (*.RAW for SVGA screens)
and SCREEN00.PLT; if there is an existing SCREENxx.BLD (*.RAW) 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.
Note: When in DOS or using a picture viewer (e.g., PICEM, VPIC,
CSHOW) or application which requires a keypress to continue, it is
necessary to hit another key after hitting the 'HOTKEY'.
LOADING PICTURES INTO GIFDOT
Four formats are accepted by GIFDOT: GIF, PCX, BLD/PLT files and TEMP
files of VGACAD; At the start of the program, you will be prompted to
select any of these formats. With VGA/MCGA, GIFDOT will display a
sampled image of the entire virtual screen or the whole screen with
*.BLD/*.PLT files. The sampled screen does not reflect the full
picture; it is intended as a visual reference for image processing
(i.e., Histogram-equalization). All other cards will load in memory;
GIFDOT automatically detects VGA/MCGA/SVGA cards.
With 16-color EGA/EEGA/VGA pictures, use EGA2VGA to process them as
SVGA GIFs with the same size (e.g., 640x480x16 -> 640x480x256) before
loading, to take advantage of richer grey scales and image processing
capabilities; EGA2VGA does not require a graphics card !
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.
When selecting a *.BLD file, a corresponding *.PLT file must exist or
an error will result; captured 320x200x256 pictures have two files:
the screen and palette. The extension .BLD stands for BLoaD and .PLT
for PaLetTe.
To use SVGA screen captures with GIFDOT, create a 640x480 or 800x600
'blank' screen with VGACAD (i.e., VSCRN menu); exit VGACAD without
deleting the TEMP files (i.e., reply 'N'o when prompted); copy your
capture *.RAW and *.PLT image to replace the respective TEMP files.
For example, if you captured an AUTOCAD 640x480x256 drawing, your
first cature will save as SCREEN00.RAW and SCREEN00.PLT. Activate
VGACAD (v1.6 and up) then create a 'blank' 640x480x256 virtual
screen. Exit VGACAD without deleting the TEMP files when prompted.
Type "copy screen00.* temp.*" <return>
You can edit the 640x480x256 screen with VGACAD (v1.6 and up) and use
its various image processing capabilities, or go directly into GIFDOT.
PRE-VIEWING DITHERED OUTPUT
Simply select the letter to initiate that function or option. Preview
in (C)GA 640x200, (E)GA 640x350, (H)ercules 720x348, (V)GA 640x480,
and (U)ser EEGA/SVGA modes up to 800x600. After selecting a video
mode you will see these options (e.g., MCGA/VGA 640x480x2).
Video Mode/Aspect Ratio: VGA 640x480
Image Width (pixels) : 640
Image Height (pixels) : 480
Resizing Factor (1-100): 100%
Dither Density (1-255): 128
Image Width and Height are set by the video mode you have chosen and
cannot be changed except when the [U]ser EEGA/SVGA mode is selected;
it is automatically adjusted by the Resizing Factor. In this example,
the Image Width and Height matches the full screen since Resizing
Factor is 100%; if it were 50% then each number will be cut in half.
To maintain your aspect ratios in SVGA or EEGA modes, start with a
Resizing Factor of 100% then reduce it. To retain an old setting,
press return and the setting will remain.
Dither Density defaults to 128; the lower this number, the more dots
will be placed (becomes brighter too). The quality of the dithering
is drastically affected by this variable; if you get some undesired
patterns, then try adjusting this variable until you get the desired
dithering. DITHER DENSITY VARIABLES WILL CHANGE PRINTING OUTPUT !
PRINTING
(inches) (pixels)
[P]ortrait 10.0 x 8.0 960 x 768
[L]arge Landscape 8.0 x 6.0 960 x 432
[M]edium Landscape 6.0 x 4.5 720 x 320
[S]mall Landscape 4.0 x 3.0 480 x 216
[T]iny Landscape 2.6 x 2.2 320 x 144
This is self-explanatory; a picture with the corresponding size in
inches and pixels will be printed accordingly. A [P]ortrait, which is
the largest possible print size, will be printed sideways; Landscape
is the normal way we view a picture. PORTRAIT size prints are
avaliable only with *.BLD/*.PLT files.
Before printing, you will be asked if you want to adjust the
settings. You can select between an [E]pson, [I]BM driver or
[O]kidata driver. You can also opt for single or double pass printing
(when your ribbon is worn), and printer port #1 or #2. While
printing, you can press <Esc> to abort the printing process.
A Horizontal Tab feature will allow you to fit as many as 8 Tiny
pictures on one page. Simply input the number of pixels that will be
used as an 'offset'.
OPTIMAL PRINTING
To get the BEST possible print-out, we suggest that you experiment
with the [T]iny Landscape option while interactively adjusting the
brightness, contrast stretching and histogram-equalization variables;
you can always [U]ndo changes if you have "messed-up" your picture.
When satisfied with the results, you can progress to larger prints.
Become familiar with the Histogram charts and the results on your
printer. After a while, you will be able to guage the quality of your
print-outs by simply looking at the Histograms before printing.
VGA/MCGA users, remember that what you see is not necessarily what you
get. In this respect, all other users are equal; you have to
interactively adjust the picture quality with your printer. I suggest
keeping 1-3 pages of tractor-feed paper during your experiments.
IMAGE PROCESSING
Selecting the [I]mage Processing function shows a Histogram of your
Original image and Modified image. All functions here are GLOBAL;
they will be used on the virtual screen image pointed to by the VDISK
path. The first histogram, labelled "Original", is the sampled image
that will be restored with the [U]ndo function; the second is the
"Modified" sampled image which reflects all the changes made.
The scales used in the histograms are based on the MODE, which is the
highest grey scale frequency in the picture; normally these are the
far bins: BLACK and WHITE. There are 64 points on the x-axis and 10
points on the y-axis. The 64 x-axis points correspond to the 64 grey
scale continuum; the entire picture is "stretched" to 256 grey shades,
which means that each point on the x-axis represents 4 grey levels.
Each point on the y-axis varies with the MODE. If the most frequent
grey shade is BLACK and 20,000 pixels (about 1/3 of sampled image),
then each point on the y-axis will represent 2,000 pixels. With this
in mind, grey shades with less that 2,000 pixels will appear as a
"flat line"; changing the Contrast or Brightness may make your
"Modified" histogram appear as a "flat line" with a few very high
bins. You can magnify the scale (i.e, reduce the value each y-axis
point represents) by pressing [M]agnify. Bins with the "┼" character
show grey shades that extend beyond the MODE (as you magnify the
scale, more Bins will have this symbol).
After modifying, the Modified histogram may not display the full
distribution since the bins are so large, smaller bins are "flat
lines". To see more, [S]lice the bins and/or [M]agnify the scale.
[S]licing the bins will cut the "anchors" of your "Modified" histogram
by 1. The first time you press [S]lice, the grey scale continuuum
spase a 2-62 grey scale; the next will be 3-61 and so forth. Since
pure BLACK and WHITE pixels tend to dominate the MODE, adjusting the
[B]ins makes he distribution more viewable. Experiment freely; you
can always press [R]eset the histogram settings.
Contrast Stretching
[C]ontrast Stretching uses a "histogram" of your pixel distribution.
Each pixel can have a grey value 0 to 255 which corresponds to each of
the colors 0 to 255. This function expands the distribution of grey
scales to extend the range of grey values from 0 to 255. For example,
a typically unequalized image may have the following distribution of
pixels. The low and high bins are the edges of the histogram
distribution. All pixels between the bins will be stretched to fill
the 256 grey range.
N ╔═════════════════════════════════════════════════════╗

After Contrast Stretching the distribution will approximate this.

s ╚═════════════════════════════════════════════════════╝
0 -------------------------127----------------------255
When prompted "Contrast Stretch (1-127 grey levels):", select a number
within that range; the high and low bins will adjust accordingly; a
value in multiples of 4 (e.g., 4, 8, 16) yield the best results.
When you have a picture surrounded by a large "black" area, that area
may not be black BUT a very dark shade of grey resulting in undesired
error-distributed patterns to appear; use a value of "1" to equalize
the grey distribution and make BLACK the DARKEST COLOR.
VGA/MCGA users can press [P]review and see the sample 320x200x256
screen. Keep in mind that the screen you see does not accurately
reflect the virtual screen image; use it merely as a visual reference
of your GLOBAL changes to the virtual screen image.
Brightness Adjustment
When this option is selected, you will be prompted with "Brightness
Skew (+64-)"; the grey range will move left or right accordingly. A
value of "-10" will "darken" all pixels by 10 grey levels (it will
skew the distribution left; conversely a value of "20" will "brighten"
by 20 grey levels (i.e. towards the right).
Histogram-equalization
Pressing [E]qualize will present several equalization distributions.
Select a desired distribution to change the image accordingly.
Flat distribution - forces grey shades to be evenly distributed for
MAXIMUM contrast and grey shade discrimination.
Sine distribution - forces grey shades to be 'normally' distributed
(i.e., pseudo Gaussian or normal binomial probability curve).
Bi-Modal distribution forces grey shades to be distributed between two
sine curves for greater bi-level contrast.
Tri-Modal distribution - forces grey shades to be distributed among
three sine curves for greater bi-level contrast with improved
mid-range.
Lite-skew distribution - forces grey shades to be skewed towards the
brighter spectrum; use this when you want to enhance the contrast of
images that are already skewed towards the brighter spectrum (i.e., a
lot of pixels fall in the upper grey levels).
Dark-skew distribution - forces grey shades to be skewed towards the
darker spectrum; use this when you want to enhance the contrast of
images that are already skewed towards the darker spectrum (i.e., a
lot of pixels fall in the lower grey levels).
NOTE: WHAT YOU SEE IS NOT WHAT YOU GET !!!. Since these histogram-
equalization algorithms are based on a 320x200 sampled screen, the
results are DRASTICALLY different when you actually dither from the
virtual screen image; it is merely a point of reference for GLOBAL
grey range manipulation. If your image looks too bright, too dark,
washed-out or 'flat' when you use the [P]review option; it will not
necessarily look that way when you actually view/save a dithered PCX
file. PREVIEW SHOULD BE TREATED AS A VISUAL REFERENCE ONLY.
USER EEGA/SVGA MODES
EEGA/SVGA users with 640x480 and 800x600 video modes can use this
function. We have included several *.CFG files of popular EEGA and
SVGA modes; do not mix these files with MVGAVU *.CFG files - they are
different. 1024x768 modes will be included in updates.
If you see your EEGA/SVGA mode, copy the *.CFG file to GIFDOT.CFG;
for example, if you have a TECMAR VGA card then copy the TECMR800.CFG
file to GIFDOT.CFG for its 800x600 mode.
"copy TECMR800.CFG GIFDOT.CFG" <return>
If your video mode is not included, simply specify your [P]arameters;
include the screen height, width, video mode calling number and Chip
Type. Almost all will have a Chip Type of "0". WIth a Video7/Cirrus
chip, your Chip Type is "1"; Everex users have a Chip Type of "2".
The video mode calling number can be specified in decimal or hex. To
enter a hexadecimal number type "&H" before the hexadecimal number
("&H12" is the same as "18", which is the VGA 640x480x16 mode); refer
to your video card manual for the decimal or hex codes (or call them
up for tech support if they forgot to list it in the manual). Once
you change the parameters, these are saved to the GIFPUB.CFG file.
