- DVPEG 3.0l read.me file
- -----------------------
-
- This is an explanation of the function of the various programs that are
- in the DVPEG ZIP archive.
-
-
- Vidsetup.exe
- ------------
- IF YOU HAVE A PARADISE VIDEO CARD RUN THIS PROGRAM BEFORE YOU RUN DVPEG
- AND DO NOT RUN THE AUTODETECTION (type N).
-
- The video setup program is the only way to edit the list of video modes
- that DVPEG uses. This program allows you to change and save options that
- DVPEG uses. These options can be changed in DVPEG but not saved. The
- main purpose of this program is to test video modes and remove those that
- do not work on your video card. Any video cards and modes that are in
- the user list are shown in red.
-
-
-
- Problems
- --------
- 24 bit graphics
- ---------------
- If the colors are not right look under F7 and change the RGB to BGR.
- For cards that use the Tseng 4000 chips there are several 24 bit modes.
- The Diamond Speed Star uses 2048 bytes/line while most others use 1920.
- Try the various modes in vidsetup and only keep those that work.
-
- Other graphics
- --------------
- *** If your moniter goes blank or the display is not stable when trying
- to display a picture, hit ESC immediately and do not use that video mode.
- If you find that the moniter does not display a stable picture in certain
- video modes then use this program to delete them. Unfortunately the S/W
- has no way to know what video mode works with your card. In some cases I
- can not even identify the SVGA video card although DVPEG supports it. To
- solve any video related problems you must use this program.
-
- It is best if you start off with the manual for your video card. That
- should tell you what works and what does not.
-
- I am sorry that the vidsetup.exe program could not be made more easy to
- use. Future versions of DVPEG will use much more extensive S/W to identify
- the video card and detect its version number, amount of memory, etc and
- avoid this whole problem.
-
-
- VGA or 16 Color Graphics
- ------------------------
- This is partially supported. It will work well for JPEGs but the
- quality for GIF, Targa and PNM pictures is not the best.
-
- *************************************************************************
- Note: If your video card is not supported with DVPEG directly you may
- be able to get it working with a "universal" VESA driver like the
- univbe VESA driver. It supports more cards than DVPEG does and is
- available at most major internet sites.
- *************************************************************************
-
- When the program starts up it will detect what type of video card you have
- and automatically enter all of the modes for that card in the user list. You
- should find the hi-lighted card on the right of the screen is the same as
- the video card that is in your system. The list of modes is in the lower
- right hand side of the screen. Hit enter twice and you will get to that
- "window" (ESC will back you out).
- If you have your video card manual, delete (delete key) any modes that are
- not listed in your manual. If some modes that your card supports were not
- entered into the list then arrow to the mode you want to add and hit INS.
- You can also add custom modes, if you know a lot about your video card, with
- the C key (poking thru the source code to DVPEG helps - ie the modes.h file).
- To test a video mode, move to the card you want to test (up/down arrows) and
- then hit <enter>. This will put you onto the upper right window where you can
- pick from the list of video modes that that card may support. With the
- up/down arrow move to the video mode that you want to test and hit space. You
- should see a series of vertical bars that fade in color as they go from left
- to right. If you can not see the bars or the image is junk then dvpeg will
- not work with that mode.
- When you find what card/mode combo's work with your system you can enter it
- into the list by hitting <insert> when you are in the upper right mode menu.
- To delete an item from the list hit enter until you get to the lower right
- user list menu. With the up/down arrow move to the mode you want to delete
- and hit <delete>.
- <enter> will move you "deeper" into the menu's while <escape> will more you
- back out. When you are at the video card menu and you hit <escape> you will
- exit the video setup program.
- At this point it will ask you if you want to save the information. If you
- have correctly made a list of working modes for your system then hit <y> and
- the file dvpeg.cfg will be created for dvpeg to use. It contains the list of
- working modes and a few other things (future features).
-
- I hope that this makes sense and you find it usable. This is the worst
- part of my viewer and it will be improved in newer versions.
-
- Advanced features
- -----------------
- Using the 'F' command you can set a color to fill the screen with (any
- combination of red, green, blue). This is good for testing to see if a
- newer video mode (15/16/24 bit) is properly supported.
-
-
- dvpeg286.exe (the 286 viewer)
- -----------------------------
- This is a 286 version of dvpeg. It is slightly slower but otherwise identical
- to the 386 version.
-
- dvpeg.exe (the viewer)
- ----------------------
- The first time this program is run it will look for the dvpeg.cfg file
- (configuration file from vidsetup.exe). If it does not exist it will run
- vidsetup. This can present a problem with some video cards.
-
- F1: help (always check this as I update the program more than I do this file)
-
-
- Advanced features
- -----------------
- You can save the tint, contrast, bright setting for automatic setting the
- next time a file is loaded. Use E to view the file instead of ENTER,
- adjust the tint, bright, contast to your liking and hit S to save them.
- To delete the settings for the picture you are viewing hit D. These
- settings are saved in the file dvpeg.vu
-
- 4DOS file descriptions should be read and printed after the file name
- If the Titles are turned on the 4DOS description will be printed.
-
-
- Selecting (toggling) Options
- ----------------------------
- Generally one letter in each line will be in upper case. When that key
- is hit the option will toggle or change.
-
-
- file_selection screen
- ---------------------
- You will always see subdirectors in the file listing and can move thru the
- directory tree by hitting enter when over a subdirectory or .. which will
- move you out one level.
-
- arrow keys: move around on the list of files/directories/drives
- Pg Up, Pg Dn: move up/down one screen full of files
- Home: move to the top of the list of files
- End: move to the end of the list of files
- ESC: exit the program
- Enter: view the file or
- move into / outof the current directory
- F1: help
- F2: change drive - just type a single letter ie d
- F3: change viewing defaults (dithering, show menu, smoothing ...)
- F4: change mask - type in *.gif, *.jpg ... (max. of 5 masks)
- F5: change sort order (ie by name, file size, date ...)
- F6: type in a new directory
- F7: change some less frequently used defaults
- there is lots of stuff under this including:
- - enable decoding to buffer for better slideshow
- - show picture sizes on the file list screen
- - show 4DOS file descriptions (instead of file name) on file list screen
- - change width of the 4DOS file descriptions on the file list screen
- - enabling 50 line text mode
- - turning the beep on/off
- - turning error messages on/off
- - changing the slide show delay
- - enabling the screen clear before draw (some video cards don't clear it)
- - change file buffer size for speed or to reduce memory usage
- - twiddle - this controls the video screen size picked if a picture is 640 * 481
- DVPEG will not use the 640 * 480 but will go to 800 * 600. If twiddle > 1 then
- the 640 * 480 screen is used - thing of it as a "slop" factor
- - ......
- space: select a file for slideshow viewing (turns filename red)
- A: select all files for slide show
- s: start slideshow
- S: run slideshow in a continous loop (ESC exits current picture and goes
- to the next, any other key causes an exit after the current picture)
- Del: deletes the file that the cursor is on
-
-
- pre_picture_viewing screen
- --------------------------
- F1: help - check this since it will be more accurate than this list
- Enter: view the picture
- ESC: exit to pick another file
- A: switch between high/medium JPEG quality
- E: turn off end of picture beep
- M: toggle this menu on/off
- L: lockout SVGA (256 color modes) ie only leave hi-color or better
- W: lockout SVGA modes that are smaller than the smallest 15/16/24 bit mode
- G: greyscale viewing of JPEGs (faster than color)
- S: change/enable shrinking of the picture to fit (only works when panning is off)
- D: toggle dithering on/off
- Q: toggle between 1 or 2 pass quantization
- P: toggle panning on/off if the picture needs it (this can take several megs
- of memory [main or disk])
- K: lock in a resolution ie if you are on 640 * 480 all pictures will use
- that size screen until you turn it off (note size not type [8/15/16/24 bit])
- arrows: select a video mode (default should be the right size)
-
-
- as the picture is decoding
- --------------------------
- ESC: exit back to the file selection menu
- N or Enter: goto the next picture
- P: goto the previous picture
-
-
- picture_painted screen (some of these work with hi_color modes)
- ----------------------
- ESC: exit to file selection screen
- arrows: pan across the picture (if the picture is > screen)
- -,+: shrink, expand the picture (if the picture is > screen)
- Pg Up: turn brightness up
- Pg Dwn: turn bightness down

- F1 ... F10 multiply all panning and color controls ie F2 is *2, F8 is *8
- S: save the bright, contrast, tint controls to be used next time this
- picture is viewed (does not work for 15/16/24 bit JPEGs)
- D: delete any stored tint ... settings for the current picture
- R: re-init video mode and redraw with all tint controls reset
- r: re-init video mode and redraw
- P: goto the previous picture
- Enter: goto to next picture
- N: goto the next picture
-
-
-
- Sounds
- ------
-
- A low frequency beep is an error indication. This can not be turned off.
- When you hear such a beep the program will pause until you hit a key.
-
- A high frequency beep is a sign that the picture is all loaded and drawn.
- This can be turned off under the F7 menu from the main screen.
-
-
-
- Files Generated by Using DVPEG
- ------------------------------
-
- dvpeg.cfg
- ---------
- Vidsetup will create called dvpeg.cfg This file stores you viewing defaults
- and describes your video card. It can only be edited with vidsetup. This
- file will be stored in the directory that vidsetup.exe was found in. If you
- wish to have multiple copies (for different video cards, different defaults)
- then copy the original to the directory where you want to make a custom one.
- Go into the directory and run vidsetup. If vidsetup finds a dvpeg.cfg file
- in the local directory it will read it and write the replacement there.
-
-
- dvpeg.vu
- ---------
- This file is created and updated by the viewing program. It has a list of
- tint/bright/contrast defaults for individual pictures. This file will be
- created in the directory that the pictures are in. If one is not found
- there the program will search in the directory that the executables are in.
- Any new defaults will be written where-ever the file is. If you have the
- pictures on CD-ROM or read-only media then you will have to:
- 1) Make a dvpeg.vu file on a writable directory
- 2) copy a dvpeg.vu file to the directory that holds the executable
-
- This is a binary file and you should be able to merge multiples together.
-
-
-
- Closing comments
- ----------------
- Please do tell me about any problems. Yes vidsetup could be made much
- easier to use but that would take a lot of time getting information from
- the video card mfg's. I welcome any information that people can forward
- to me so that I may support more video cards.
-
- If you are interested in the latest executables or source code you can
- reach me thru my addresses. FTP to sunee.uwaterloo.ca in directory
- pub/jpeg/viewers is the easiest way to get the latest version. If you
- do not have internet access I will send out copies thru the mail. Just
- send me a letter with a donation to cover postage and disks. Don't
- forget to tell me why type of disk (5.25" or 3.5" and the format ie
- 360k, 1.2M, 1.44M).
-
-
- Updates
- -------
- This program undergoes rapid changes at times when I have nothing better
- to do. The easiest way to get the most recent version is thru the
- internet. I work on whatever interests me at the time. The biggest
- problem is the lack of information on video cards. I add what I can
- when I get the information. Of course I can only test the S/W on the
- machine that I have (currently a Trident 8900 video card) and so offer
- no guarantees. If you make any changes I would appreciate hearing
- about it so that I can offer it in future versions.
-
-
- Donation
- --------
- If you find this program usefull or are requesting an update thru the mail
- I do not turn down cash offers ;-)
