-
- WHAT IS MVGAVU ?
-
- MVGAVU is a GIF decoder/viewer/slideshow utility and component of VGACAD.
- MVGAVU handles GIFs up to 2KBx2KBx256 and shows the whole picture w/out
- scrolling; it also features a UNIQUE 256-color rendering scheme in
- 16-color EGA/VGA/SVGA modes for viewing multiple/animated images. As a
- versatile slideshow, it automatically determines the BEST viewing mode.
-
- You can also view PCX (Zsoft/PCPaintbrush) support for 2-color, 16-color
- and 256-color image files.
-
- MVGAVU supports TARGA file (16/24/32 bits) viewing through unique
- 16/256-color rendering schemes to view all those THOUSANDS of "colors"
- in ALL modes supported. BMP (Windows 3.x) 16-color, 256-color and
- 24-bit (16.7 Million color) image files are also supported.
-
- New! HiColor Mode support added to see those 16/24/32-bit Targa and
- 24-bit BMP files in 640x480x32K (eg., ATI VGA Wonder XL) and/or
- 800x600x32K! with Tseng 4000 cards w/ Sierra DAC
-
- eg. Cardinal VGA732
- Diamond SpeedSTAR HiColor
- Focus 2 the Max VGA4000
- Micro-Labs Ultimate VGA/HiColor
- Orchid Prodesigner IIs
- SOTA Lightning VGA
- STB PowerGraph Ergo-VGA HiColor
- United Ultra Image HiColor
-
-
- REQUIREMENTS
-
- MVGAVU requires a PS/2 or EGA/MCGA/VGA/SVGA video card. 512KB of
- RAM is required, although it uses less than that. The BRUN41.exe
- runtime module MUST be present in your DOS path.
-
-
- CONFIGURING MVGAVU
-
- BEFORE DOING ANYTHING, configure MVGAVU by selecting (C)ard; MVGAVU
- is initially set for "VGA or PS/2 Model 50". If the "VESA" setup was
- configured previously, you MUST configure MVGAVU by typing
-
- "MVGAVU -C" <ret>.
-
- A list of Video card "types", based on their chipset family, are
- presented. Enter the number that matches your card. When selecting
- SVGA cards, check your manual or manufacturer for the chipset (e.g.,
- ATI, Tseng, Paradise, Video7, Oak, etc..); when in doubt, select
- choices 253, 254 or 255. You will also be asked to specify the amount
- of video RAM present and, if ATI or Tseng4000 chipsets are selected,
- HiColor capability option. BE SURE THAT MVGAVU.EXE IS LOCATED IN YOUR
- DEFAULT DRIVE/PATH TO ENSURE HARCODED CONFIGURATION.
-
- Trident TVGA card users that have the supposedly rare 'BR versions'
- will notice that the bank switching will be erroneous. We tried to
- accomodate this version but ended up compromising the more popular
- TVGA 8800 and 8900 versions <sorry>.
-
- The Trident 1024x768x256 mode is not supported at this time since it
- uses a very peculiar, card specific, bank switching methodology (ie.,
- it conflicts with SVGA display conventions). Video mode support is
- limited to 800x600x256 or 1024x768x16, if available.
-
- Some Everex 678 (w/ Trident chip) have experienced compatibility
- problems. If the 1024x768x16 mode works but fails in all other modes,
- then you may have a defective card. Try using the VESA setting
- described below; if that fails then you really have a problem card.
-
-
- LAUNCHING MVGAVU AS A DOS APPLICATION UNDER WINDOWS 3.X
-
- HERCULES STATION CARD USERS SHOULD NOT USE THIS OPTION.
- ======================================================
-
- Before implementing the following steps, please ensure that the
- BRUN41.EXE file has access to your PATH or has been copied into the
- \WINDOWS\SYSTEM sub-directory.
-
- 1. If you don't have a PROGRAM GROUP for DOS applications then
-
- 1.1. Click "File" under the Program Manager window.
- 1.2. Select "New".
- 1.3. Select "Program Group".
- 1.4. Click "OK".
- 1.5. Enter a DESCRIPTION for this "Program Group"
- (eg., "DOS Apps")
- 1.6. Click "OK".
-
- 2. Click (activate) your "DOS Apps" window.
- 3. Click "File" under the Program Manager window.
- 4. Select "New".
- 5. Select "Program Item".
- 6. Click "OK".
- 7. Enter the full pathname of MVGAVU at COMMAND LINE and include
- any Command Line processing option (if desired) discussed at a
- latter section of this manual.
-
- eg., If MVGAVU.EXE is located under the \VGACAD directory then
- enter "\VGACAD\MVGAVU" at the COMMAND LINE.
-
- If you wanted the AutoMode processing option to be activated
- to select video modes up to 1024x768x256 then you would enter
- "\VGACAD\MVGAVU -m" at the COMMAND LINE.
-
- NOTE: You can also use the BROWSE function of this window to
- select MVGAVU instead of actually typing it in at the
- COMMAND LINE.
-
- 8. If you wish, "Change Icon" - "DOS" icon is preferred though.
- 9. Click OK.
-
-
- VESA IMPLEMENTATION
-
- MVGAVU now supports the VESA (Video Electronics Standards Association)
- application interface. By selecting VESA (ie., card "18"), virtually
- all SVGA modes supported by your card can be utilized and integrated
- with all of MVGAVU's processing options. VESA mode support includes:
-
- 800x600x16
- 640x400x256
- 640x480x256
- 800x600x256
- 1KBx768x16
- 1KBx768x256
-
- VESA support requires you to load a card-specific resident program
- before VESA can be used. An error message - "VESA not detected!"
- will result if VESA has not been previously loaded.
-
- Under certain circumstances, MVGAVU will reject a VESA mode; it will not
- become available if it conflicts with "common" SVGA implementation. Any
- mode that requires two windows ("bank switching methods") to read and
- write to video memory or uses a window other than A000 hex will be
- rejected (eg., Trident 8900 1024x768x256 mode).
-
- The old ATI SVGA 1024x768x16 mode (trigerred via mode 65 hex) is not
- supported via VESA - it is supported and hardcoded if you select the
- ATI card instead of VESA. With the new ATI cards you can have ALL
- VESA modes or hardcoded modes up to 1024x768x256.
-
-
- LOADING PICTURES INTO MVGAVU
-
- MVGAVU accepts [G]IF, [T]arga, [W]indows (BMP), PCX (PC Paintbrush) or
- [B]ASIC (BLD+PLT) file types. Select any filename by moving a high-
- lighted bar (with arrow keys) and pressing <return> key. If you have
- more than 184 files, the columns of files listed will scroll when either
- margin of the screen is reached. <Home> moves to the first file while
- <End> moves to the last file. <PgDn> shows the next 184 files while
- <PgUp> shows the previous. <Spc> allows changes to the PATH, while
- <Esc> exits. BLD files MUST have a corresponding *.PLT file or a error
- message will follow.
-
-
- COMPATIBILITY
-
- The BRUN41.exe runtime module HATES 'Shadow RAM' (eg., putting your
- VIDEO BIOS in low or high RAM); it 'hangs' (at least on our 386 SX).
- If MVGAVU 'locks-up' at start-up then you have this problem too;
- disable 'Shadow RAM' (eg., via CMOS set-up) and it should work.
-
- There are several COMMAND LINE OPTIONS that are NOT available from the
- MVGAVU Expert Menu. All other processing options described in a latter
- section of this manual can be invoked despite these option settings.
-
- MVGAVU -H <ret>
-
- "-H" HiColor Enable. If this command is invoked from the command line,
- HiColor (32KB-color) modes will be made available at the Expert Menu
- when Targa 16/24/32 or BMP 24-bit files are detected. If HiColor modes
- are not setup during configuration then it can be accessed this way.
- No verification of HiColor capability is done, CHECK YOUR CARD'S MANUAL
- TO SEE IF IT SUPPORTS IT!
-
- Note: HiColor modes and the CEG/Edsun DAC modes are totally different;
- the former is a "true" 32KB color mode while the latter is a
- peculiar "anti-aliasing"/smoothing mode which is NOT supported
- by MVGAVU at this time.
-
-
- MVGAVU -D <ret>
-
- "-D" Disable Auto-Expanded Memory usage. Expanded memory is required
- for those GIF89a "crashers" that require MASSIVE amounts of memory to
- restore a screen. The LIM 4.0 EMS spec is required to use expanded
- memory, if your EMS driver does not conform then unpredictable results
- will happen such as getting strange colors in restored areas. Disable
- Auto-EMS usage to allocate 96KB of low RAM for screen storage; this
- should work with most GIF 89a images that conform to Jim Burton's
- "Rules for GIF89a MIGs".
-
-
- MVGAVU -E <ret>
-
- "-E" EGA only mode forces EGA 640x350x16 to be the ONLY mode to be
- selected by the user or MVGAVU during automatic mode selection (ie.,
- hitting <return> key.
-
- If you are having compatibility problems (particularly SVGA mode and/or
- bank switching) with MVGAVU please contact Lawrence Gozum [73437,2372]
- via CompuServe's
-
- E-Mail
- or
- PICs Forum
-
-
- VIEWING TARGA FILES IN MVGAVU v5.1
-
- o Only UNCOMPRESSED, UNMAPPED Targa (16/24/32 bit) files are supported.
- o TARGA files must be <= 2048x2048.
- o With ANY 256-color modes, 32768 color "pairs" are matched/rendered.
- o With any 16-color mode, the 32768 color "pairs" method is used, then
- a 256-to-16 color algorithm is applied, unless the image requires
- drastic resizing/image aspect ration correction on the Y-axis, then a
- posterized 256-color alogorithm is used instead of the SVGA 32768
- color "pairs" method.
- o Slideshows are disabled.
- o AutoCentering is disabled.
- o HercGS 640x480x32K mode replaces 640x480x256 mode when TARGA files
- are selected; saving the screen in this mode is disabled.
- o HercGS 512x480x16M mode is made available when Targa 24/32 files
- are detected; saving the screen in this mode is disabled.
- o HiColor 640x480x32KB or 800x600x32KB modes (eg., Diamond Speedstar,
- and ATI VGA Wonder XL) are made available when Targa files are
- detected; saving the screen in these modes is disabled.
-
-
- Note: TGA files are best viewed with "Fix Aspect 1:1" or "Fix Aspect TGA"
- In 256-color modes, view TGA files with the highest mode possible
- (eg., 1KBx768x256) or use the grey processing option for maximum
- detail; processing options are discussed in latter section.
-
-
- VIEWING BMP (Windows 3.x) FILES WITH MVGAVU v5.1
-
- o Only UNCOMPRESSED 16-color, 256-color and 24-bit (16.7 MB color)
- files are supported.
- o BMP files must be <= 2048x2048.
- o Slideshows are disabled.
- o AutoCentering is disabled.
- o BMP files are best viewed with "Fix Aspect 1:1" processing option
- discussed in latter section.
- o HiColor 640x480x32KB or 800x600x32KB modes (eg., Diamond SpeedSTAR,
- and ATI VGA Wonder XL) are made available when 24-bit BMP files are
- detected; saving the screen in these modes is disabled.
-
-
- VIEWING PCX FILES WITH MVGAVU v5.1
-
- o Only RLE 2-color, 16-color and 256-color image files are supported
- (essentially covers ALL PCX files except CGA 4-color image files).
- o PCX files must be <= 2048x2048.
- o Slideshows are disabled.
- o AutoCentering is disabled.
-
-
- SELECTING VIDEO MODES
-
- On default MVGAVU is set to AutoMode with "Expert Menu:OFF"; after
- selecting a file, MVGAVU will immediately show the image. Pressing
- <return> after picking a GIF file triggers automatic mode selection.
- MVGAVU selects the BEST video mode, based on your video card
- configuration. Pressing <Esc> aborts viewing and lets you reselect
- a new file.
-
- Set "Expert Menu:ON" at the opening menu if you want to use processing
- options or to select specific video modes for viewing.
-
-
- HiColor modes
-
- 640x480x32KB or 800x600x32KB modes (eg., Diamond Speedstar, and ATI VGA
- Wonder XL) are supported by MVGAVU. HiColor modes are made available
- at the Expert Menu ONLY when Targa 16/24/32-bit or BMP 24-bit files are
- detected. Automode support is not included at this time, due to downward
- compatibility reasons. CHECK YOUR CARD'S MANUAL TO VERIFY AVAILABILITY !
-
- * If HiColor capabilty is not configured at the start then
- invoke the "-H" command line option (ie., "MVGAVU -H");
-
- To view images in HiColor modes,
-
- (1) turn Expert Menu ON;
- (2) pick a Targa 16/24/32-bit or BMP 24-bit file;
- (3) select mode (eg., [H]iColor 640x480x32K) at the Expert Menu.
-
-
- Unsupported MVGA (Medium-resolution VGA) modes
-
- The 320x400x256 mode is the safest since it uses minimal VGA register
- modification and is safely within tolerances of PS/2 monitors; it should
- run on any "register-compatible" VGA card. It has an interesting aspect
- ratio - double the vertical resolution of MCGA/VGA 320x200x256; many
- Amiga, Atari and MacII GIFs have this aspect ratio; viewing GIFs in this
- mode replicates "what the originator saw". If the 320x400x256 mode
- fails, your card is BIOS-COMPATIBLE ONLY !
-
- The 360x480x256 mode pushes generic VGA cards to its theoretical limits!
- With 270% more resolution, view 640x480x256 GIFs with more detail and
- less "jaggies". If the 360x480x256 mode fails, your card is not as
- "register-compatible" as it claims to be.
-
- The 640x400x256 Tseng SVGA was created to view 320x200x256 GIFs more
- clearly due to 400% more resolution - aside from adding the missing
- mode to its SVGA repertoire. Amiga, Atari and MacII GIFs use this
- aspect ratio multiple and look as close as possible to "what the
- originator saw" with it.
-
- View Jovian VIA scans (320x240x256 GIFs) in 640x480x256 or 800x600x256;
- these GIFs have the same aspect ratio and have the same effect as
- viewing 320x200x256 GIFs in the 640x400x256 mode.
-
-
- Preset SVGA modes
-
- MVGAVU has hardcoded support for many SVGA chipsets based on your video
- card configuration. SVGA MODES ARE NOT VERIFIED; YOUR VIDEO RAM AND
- CHIPSET LIMITS YOUR CHOICES; CHECK YOUR MANUAL !!!
-
-
- SVGA/EEGA User modes
-
- SVGA/EEGA User modes are made available ONLY when HiColor modes are
- disabled. Only one or the other are made available.
-
- To use User modes, press [U]ser Mode. On default, this mode is set to
- EGA 640x200x16. To set your own modes specify the Screen Width, Screen
- Height, colors (16 or 256), Video Mode, and Chip type (9=EEGA). Several
- *.CFG files are included; copy a special video mode (e.g., 512x480x256)
- to MVGAVU.CFG and it will be invoked when you use the "U" option. CHECK
- YOUR CARD'S MANUAL TO DETERMINE IF IT SUPPORTS IT!
-
- To set a 256 or 16 color mode, press [R]evise. Once edited, it is saved
- and recalled anytime. Type the video mode in decimal (e.g. 255) or hex
- (e.g. &HFF); HEX ENTRIES *MUST* BE PRECEDED BY THE "&H" CHARACTERS.
- 16-COLOR MODES (UP TO 800x600 EXCEPT EVEREX & VIDEO7 MODES) MUST ALWAYS
- USE "9" (for EEGA) SINCE IT WILL TELL MVGAVU TO USE THE HARDCODED
- STANDARD PROCEDURE. FOR MODES ABOVE 800x600 (e.g. 1024x768), YOU MUST
- USE THE CORRECT CHIPSET (eg., ATI, PARADISE, TSENG, VIDEO7, ...).
-
-
- EGA/EEGA/VGA 16-Color Modes
-
- If a GIF or BMP or PCX file has more than 16 colors (e.g, 256) then a
- unique 16-color rendering method will implemented (eg., 640x350x16).
- Viewing 1024x768x256 GIFs in 1024x768x16 will yield more detail than
- viewing in interpolated 640x480x256.
-
-
- PROCESSING OPTIONS
-
- There are SEVEN (7) processing options:
-
- Safety w/ MIGs
- Normal w/ MIGs
- OneMeg w/ MIGs
- Fit to Screen
- Fix Aspect 1:1
- Fix Aspect TGA
- Fix Aspect 5:6
-
- The first six options can be triggered from the command line.
-
- "Normal w/ MIGs" - this is the optimal processing option. Multiple
- Image Graphics/GIFs (87a and 89a) will be rendered. Depending on your
- card configuration, when using automatic mode selection (ie., <return>)
- or command line viewing, the best video mode will be selected; this will
- include 800x600x256 and 1024x768x16 modes, if available.
-
- Note: Old Paradise cards excluded 800x600x256 and 1024x768x16 modes;
- USE ONLY THE "Safety w/ MIGs" OPTION BELOW IF YOU HAVE THE
- OLD PARADISE CARDS.
-
- "Safety w/ MIGs" - this option is the DEFAULT; it is similar to "Normal
- w/ MIGs" but excludes the 800x600 and 1024x768 modes, even if they are
- available to ensure that fixed-frequency monitors, with 640x480 as its
- max, will not be affected. Moreover, setting this option will avoid
- calling the 800x600 or 1024x768 modes which is excluded by some video
- cards (eg., old Paradise cards and some Trident cards).
-
- "OneMeg w/ MIGs" - this is essentially similar to the "Normal w/ MIGs"
- option but includes the 1024x768x256 mode, if available.
-
- Note: The processing options (above) will call the "Fit to Screen"
- processing option (below) if the image exceeds screen parameters.
- The AutoMode <return> key is disabled with the following options.
-
- "Fit to Screen" - this option decodes the FIRST image and fits that
- image to maximum screen dimensions. This is useful for resizing images
- and subsequently saving/encoding them with the [tab] option described in
- a latter section of this manual.
-
- "Fix Aspect 1:1" - with this option, certain GIFs that have the same
- screen and image descriptors (e.g.CARMEN2) will be corrected for
- accurate rendering (otherwise they will seem distorted). "1:1" aspect
- assumes originator was using a "square" aspect ratio. If you have 100
- pixels on all sides of a square, the square should appear as a SQUARE on
- your monitor, not some rectangle. 320x240(Jovian VIA), 640x480, 800x600
- and 1024x768 modes should have "square" aspect ratios. Use this option
- to fix such GIFs (e.g., SYLVIA.GIF, PAULINA.GIF, FMAID.GIF, ... ).
- BMP FILES ARE BEST VIEWED WITH THIS PROCESSING OPTION SINCE THERE IS
- NO IMAGE/SCREEN DIFFERENTIATION.
-
- "Fix Aspect 5:6" - this option is similar to the 1:1 processing option
- but assumes that the originator was using a 320x200 or 640x400 screen
- aspect ratio (eg., Amiga, Atari or MacII). AutoMode <return> key is
- disabled.
-
- Note: Almost all SVGA cards, due to monitor and "clock" contraints
- tend to implement the 800x600x256 mode with a 5:6 rather than
- a 1:1 aspect ratio.
-
- "Fix Aspect TGA" - this mode is intended for viewing TARGA (*.TGA) files
- which typically originate from a 512x480 screen. If the image looks
- "too fat" then use the "Fix Aspect 1:1" processing option.
-
-
- GREY CONVERSION
-
- If you require grey images for desktop publishing (DTP) applications,
- then use MVGAVU's grey processing option at the Expert Menu. By simply
- pressing the [G]rey Option, all images will be converted to grey shades.
-
- Viewing TARGA images with the option is particularly useful if you
- want to see a LOT of detail, albeit without color. If you view TARGA
- images with this option and subsequently save it, you can process the
- file for DTP or printing with GIFPUB ! The palette contrast and
- brightness functions will work with this option, making it an ideal
- preprocessor for DTP.
-
-
- ADJUSTING THE VIDEO MODE
-
- This feature is disabled when using extended Hercules Graphics Station
- or HiColor (32KB color) video modes.
-
- WARNING: TO USE THIS FEATURE YOU *MUST* HAVE A REGISTER-COMPATIBLE VGA
- CARD AND MULTIFREQUENCY MONITOR. DEPENDING ON SOPHISTICATION OF YOUR
- HARDWARE, MINOR ADJUSTMENTS TO VIDEO MODES MAY TOTALLY DISRUPT THE VIDEO
- SYNCING PROCESS, BE PREPARED TO PRESS THE "*" KEY TO RESET IF SYNC
- SIGNALS ARE UNFAVORABLY DISRUPTED.
-
- Some video modes (e.g., 800x600) have distorted aspect ratios (i.e.,
- supposed to have 1:1 aspect ratios but isn't). To correct this, you can
- (1) compress the image vertically/horizontally or (2) offset the image
- on your monitor as if you were adjusting the vertical and horizontal
- scanning controls of your monitor. If you set your monitor for
- 1024x768x16, you will normally find that modes such as 960x720x16 tend
- to be distorted.
-
- There is a growing amateur interest in VIDEO GRAPHICS via 'GENLOCK'
- add-on cards (e.g., Jovian VIN, Willow VGA-TV). By adjusting the video
- mode you can control the aspect ratio and overall image size sent to your
- TV or video tape. 320x200 and 640x400 modes tend to send images that are
- smaller than the total TV/Video image; centering may be required. With
- 640x480 or greater modes, the image may tend to be larger or distorted;
- aspect ratio, image size and location adjustments may be required to
- match 'real' video images with your computer graphic images.
-
- After an image is displayed, press "[A]djust Monitor. The following key
- options will be activated; this feature can be invoked in any video mode.
-
- [->] move image right [ - ] compress horizontal aspect
- [<-] move image left [ + ] decompress horizontal aspect
- [dn] move image down [Ins] compress vertical aspect
- [up] move image up [Del] decompress vertical aspect
- [ * ] RESET ADJUSTMENTS
- [Esc] exit
-
-
- ADJUSTING CONTRAST & BRIGHTNESS
-
- This feature is disabled when using extended Hercules Graphics Station
- or HiColor (32KB color) video modes.
-
- If you view in any mode except EGA, you can adjust contrast, brightness,
- and color level. Virtually ALL palette modifications can be emulated
- with these "knobs". Moreover, you can add or substract individual
- quanta of red, green or blue components.
-
- Make sure your NUMLOCK key is OFF !
-
- [Esc] or any other key (e.g., [return] or [spc]) will exit.
-
- [->] increase brightness [+] increase color level
- [<-] decrease brightness [-] decrease color level
- [dn] increase contrast [*] reset palette
- [up] decrease contrast [A] Adjust Monitor
-
- The following keys are CASE SENSITIVE.
-
- [R] increase RED level [r] decrease RED level
- [G] increase GRN level [g] decrease GRN level
- [B] increase BLU level [b] decrease BLU level
-
- With VGACAD you can import the adjusted palette in your edited picture
- by pressing [backspace] key. When editing a SVGA GIF via VSCRN (i.e.,
- "virtual screen"); eNCODe that GIF and view it with MVGAVU; adjust the
- palette, press [backspace] then exit to import that palette.
-
-
- SAVING RESIZED MVGA/SVGA GIFs OR MIGS (Multiple Image Graphics/GIFs)
-
- You can 'downsize' (squeeze) SVGA GIFs (e.g., 640x480x256) or expand
- small GIFs (e.g., 320x200x256) to 320x400x256 or 360x480x256. Downsize
- SVGA GIFs for fast-decoding or enlarge small GIFs for enhanced image
- processing with VGACAD or reduce odd SVGA GIFs (e.g., DGNLDY) to smaller
- SVGA modes (e.g., 640x400x256). View your GIF with any video mode and
- press the [tab] key.
-
- MVGASCRN.RAW and MVGASCRN.PLT files will be created for GIF, PCX or BMP
- (Windows 3.x) encoding with VGAFIL. NYBLSCRN.RAW and NYBLSCRN.PLT files
- will be created for 16-color GIF encoding with VGAFIL. Subsequent saves
- overwrite these files; encode with VGAFIL (which can be found in the
- *.ZIP files of VGACAD (v2.0 and up) or VGACAP (v6.0 and up), and rename
- immediately to preserve them.
-
- MIGs are usually several 'overlayed' images which simulate animation.
- MVGAVU supports GIF MIGs. Since MIGs tend to change what you initially
- see from what you see at the end of the GIF, you may want to save the
- final rendered image rather than the first one for editing with VGACAD
- or conversion to another image format or mode. Simply save the final
- rendered image as you would a resized image (ie., using the [tab] key)
- and convert it with VGAFIL. VGAFIL supports GIF, PCX, TGA (Targa 16)
- and BMP (Windows 3.x) encoding to edit the image with any program that
- supports those file formats.

-
- GIF SLIDESHOWS
-
- Up to 4096 GIFs can be viewed in a slideshow. Move the cursor to select
- files and press [+] key to mark or [-] to unmark. After selecting files
- press [S]how to start and you will be presented with transition options.
- You can adjust the "delay" factor between each "slide" by adding pauses
- up to 30 seconds and use one of the various transition effects. During
- the show, press any key (three to four times) while the show is running
- to exit. MVGAVU selects optimal video modes based on your video card
- configuration and command line processing option selected.
-
-
- COMMAND LINE VIEWING & BATCH PRESENTATIONS
-
- MVGAVU can be used in batch (*.BAT) files for presentations. In Command
- Line mode, only your picture is displayed and pressing any key (except
- [tab], [backspace], [A]djust Monitor and Color/Picture adjustment keys)
- after its display will end the program. No menus or prompts interfere.
-
- Type "MVGAVU ?" for help or type
-
- "MVGAVU [processing option] filename <ret>"

-
- with no extension and optional path (e.g.,MVGAVU \gif\wett). GIFs are
- viewed via automatic mode selection; the range of video modes selected
- from and how the graphic is rendered depends on your video card
- configuration and processing option selected.
-
- MVGAVU searches for the first matching *.GIF, then it searches for a
- *.TGA file then, then a *.BMP file, then a *.PCX file, and lastly a
- *.BLD file (which can be viewed only in MCGA 320x200x256 mode and must
- have matching *.PLT files in the same drive/directory).
-
-
- THE CHAINED VGACAD ENVIRONMENT
-
- BRUN41.exe is a runtime module distributed under licence with Microsoft
- in connection with this program. Place it with MVGAVU or anywhere your
- DOS PATH has access to. MVGAVU is a part of VGACAD. ONLY ONE COPY OF
- BRUN41.EXE IS REQUIRED.

-
- As token of our appreciation (i.e., to registered users), we will send
- you the the latest version of the VGACAD system; many of the programs
- listed below do not require a graphics card.
-
- GIFPUB - converts 256 color GIF/PCX files to B&W images desktop
- publishing (DTP) as .PCX (Ventura, First Publisher, Publisher's
- Paintbrush, WP, Pagemaker). Variable sizing/contrast/brightness.
- Includes printing on IBM/Epson, HP Laser and compatible printers.
- Variable sizes. 8 pics/page and/or Single/Double Pass printing on
- dot matrix printers. Preview in CGA/HGC/EGA/VGA/EEGA/SVGA. Histogram-
- equalization. No graphics card required.
-
- GIFBIT - converts B&W PCX files (e.g., scanner output to 32KBx32KB !)
- to grey shades for VGACAD image processing, GIFPUB redithering or
- printing, or VGA2EGA conversion - it edits those "scan line jitters".
- Viewing modes in MCGA/VGA/SVGA. No graphics card required.
-
- SQZGIF/EGA2VGA - converts LARGE GIF/PCX pics (to 2KBx2KBx256) to
- several sizes and video modes using "color averaging" to blend/smooth
- "jaggies" or fast interpolation. Variable sizing. Also, converts
- GIFs (16 colors and below) and creates up to 256 new colors; outputs
- directly to GIFPUB, GIFDOT, VGACAD, MVGAVU, VGA2CGA or VGA2EGA.
- No graphics card required.
-
- GIFHEX (formerly VGA2EGA) - converts 256-color pictures to 16-color
- EGA or VGA . Error-distributed dithering. User support to 1024x768.
- Variable sizing/RGBICMY/contrast. EGA/MCGA/VGA required.
-
- MVGAVU - latest version.
-
- VGACAD - extensive paint/image processing program for VGA/MCGA users
- (edit GIFs up to 32KBx32KBx256 !!!); airbrushes, color and grey image
- processing functions (smoothing, noise removal, shading, contrast
- stretching, edge detection, ...), splines, Cut&Paste, variable sizing,
- 256-color gradient/pattern fills, MORE ! Full screen SuperVGA editing
- and image processing function to 1024x768x256. 360x480x256 support.
- MCGA/VGA required.
-
- VGA2CGA - converts 256 color GIFs to CGA! See "405" colors in an
- unsupported 160x100x16 CGA mode. CGA/EGA/MCGA/VGA required.
-
- MAC2GIF - converts .MAC ("readmac") pictures to 5-16 grey shades or
- color and saves to .GIF or BLD/PLT file. EGA/MCGA/VGA required.
-
- VGACAP - resident utility to capture 256-color MCGA/VGA or SVGA images.

-
- VGAFIL - GIF, PCX, BMP (Windows 3.x) and TGA (Targa 16) encoding
- utility. Accepts ALL RAW file formats used by our utilites as well as
- BLD/PLT files. This utility replaces RAW2GIF, RAW2PCX and BLD2GIF.
-
-
- WHAT'S NEXT ?
-
- Aside from enhancing existing releases with greater capabilities (e.g.,
- expanded memory, virtual screen, SVGA functions, other graphics
- formats), we are developing VGACBT (Computer-Based Training program)
- and MANNEQUIN for Advertising/Fashion Design or creating your own
- artistic nudes. We will try to develop and integrate more image
- processing functions for all our applications; if you have any image
- processing functions you would like to see, please let us know.
-
- In the short term, we are developing RGBLAB. This is a color reduction
- utility to 'downsize' 24-bit or 16 Million-color pictures to 256-colors.
- RAW red, green and blue files, TIFF (*.TIF), TARGA (*.TGA) and Windows
- 3.x (*.BMP) files will be the main input sources. IDTVGA dithering will
- play a key role in previewing or rendering 24-bit images in SVGA
- 256-color modes.
-
- Support maverick authors like us and we will continue developing
- products like nothing seen commercially - otherwise they will simply
- "DIE" from lack of support ! Compare the cost/benefit ratio of any of
- our products with commercial products. You, and you alone, determine
- whether it will be worthwhile to continue developing. Support the
- User-Supported (Shareware) concept. Register your Shareware copies.
