- Dvpeg 2.1 - dvpeg.doc file
- ---------------------------------
-
- Use: Dvpeg is a DOS based (286 or up) JPEG / GIF viewer that will run
- under DOS / Windows / OS/2.
- The JPEG conversion code came from the Independant JPEG Group (more
- info is in the source code) and a lot of the video drivers came from
- the vgakit41.zip. Their code was free so this is as well.
-
- To run dvpeg use: dvpeg
- or dvpeg picture_name
- or dvpeg <drive> <path> <file_mask or file_name>
-
- Memory requirements: Dvpeg will use a lot of memory if the image is going
- to be panned (typically 1+ meg) and will look for EMS or extended memory.
- If no memory can not be found it will use the hard drive to store the
- temporary information (much slower). So if you want to see something fast
- setup dvpeg for about 1 - 2 megs of EMS. If you are running out of memory
- then give it some more (some of those 1600 * 1200 images will use 3.8M if
- you are panning a hi_color image!).
-
- Remember - for speed with jpeg images use 'G' for greyscale viewing or one pass
- quantization.
-
- To file out about options use just hit F1 at any time.
-
- Check the read.me file for detailed information about vidsetup.exe, dvpeg.exe,
- dvpeg286.exe
- Basically:
- vidsetup.exe - allows setting of defaults for the viewer (dvpeg) and
- testing of video modes
- dvpeg.exe - 386/486 jpeg/gif viewer
- dvpeg286.exe - 286 jpeg/gif viewer
-
- Please send any comments / suggestions to praetzel@sunee.waterloo.edu
-
- P.S. Many thanks to my beta tests and those who helped me work out some bugs.
- Version 2.0 should be the first one with a bit more help and doc's than
- this. I would also like to thank Tom Lane and the IJG along with various
- people who have compiled video information (VGAKIT, VGADOC) that is on
- most big sites.

- ******************************************************************************
- This is a list of the supported cards and modes.
-
- Not all cards from a Mfg will support all of these modes. In most cases you
- will need 1 Meg of video ram for the hi resolution modes and some modes (like
- the hi_color ones) are recent additions and only supported by the most recent
- cards sold. To test a certain mode on your video card/moniter setup use
- vidsetup.exe Usually if the mode is not supported the video card locks up
- and you can't get back to the text screen. The only solution is to reset
- the computer.
- There may be more or less modes/cards supported than is listed here. I will
- try to keep this updated but for a complete list run vidsetup and goto the
- card you want to check out.

- Diamond SpeedStar 24X, Paradise, WD compatable cards

-
- ** All modes for this card have to be added by hand. The card is not
- ** automatically detected.
-
- Should be supported for all 256 and hi-color modes. The 24 bit mode may not
- work.

- I doubt that these modes will work.
