GIFDOT (c) Copr. 1989 Lawrence Gozum & Marvin Gozum ─────────────────────────────────────────────────── User Manual DISCLAIMER This product is distributed AS IS. The authors specifically disclaim all warranties, expressed or implied, including ,but not limited to, implied warranties of merchantability and fitness for a particular purpose with respect to defects in the diskette and documentation, and program license granted herein, in particular, and without limiting operation of the program license with respect to any particular application use or purpose. In no event shall the authors be liable for any loss of profit or any other commercial damage including but not limited to special, incidental, consequential or other damages. 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.

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. THE INTEGRATED VGACAD SYSTEM BRUN41.exe is a runtime module distributed under licence with Microsoft in connection with this program. Place it with GIFPUB's directory or anywhere your PATH has access to; ONLY ONE COPY OF BRUN41.EXE IS REQUIRED. TEMP files of GIFDOT can be used directly by VGACAD (v1.6 and up); remember to load the TEMP.PLT file from the FILES MENU before invoking the VSCRN MENU.
