Dvpeg 2.8 - 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 file) 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
or
dvpeg <drive> :\ <path> \
list_of_picture_names_with_spaces
<file_mask or file_name>
Option: If you give a list of picture names followed by a '-' character
DVPEG will show the pictures (pausing for a keypress) and then
automatically
exit.
ADVANCED OPTION: You can pass the name of a config file to DVPEG by
giving
it as the first arguement. This way you can have several different
configuration files for networks ...
Advanced Option
--------------The first file <path> \ file_name passed to dvpeg will be tested to see
if it is a configuration (dvpeg.cfg) file. This allowes network users
to direct the program to a configuration file that has been setup for
a certain video card and have several configuration files available.
It
also allows normal users to create several configuration files; save
them
under different name; and use them for different defaults ...
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 about 1 - 2 megs of EMS or XMS. If you are running out of memory
then give it some more (some of those 1600 * 1200 images will use 4+M
if
you are panning a hi_color image!).
Memory Problems: If you are running out of memory then most likely it is
the 'low' or below 640k memory. You will have to remove some drivers
or
other items that are using the lower memory.
One way to free up a bit
of
memory
shows)
(and speed up viewing) in DVPEG for JPEGs is to:
use the 1 pass quantizer or Grey scale
turn off cross block smoothing (defaults to off)
turn off the panning (you can still shrink the image as it
To find 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.uwaterloo.ca
P.S. Many thanks to my beta testers and those who shared their
knowledge.
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.
More cards and modes are supported with the UNIVESA.EXE program.
IT IS NOT COMPLETE. CHECK VIDSETUP FOR THE FULL LIST OF SUPPORTED MODES
(or the file modes.h in the source code).
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.
