Offe is proud to bring you our GIF display software for the IBM PC. It is
fast, supports a number of different display boards, handles corrupted GIF
files well, and provides automatic/manual enlargement/reduction. You can set
the data directory, specify a list of files to be viewed with few keystrokes,
and abort the display in the middle if you wish. You can run it in a pre-
programmed mode with no keyboard input.
We hope you like our product.

VUGIF Version 1.70 - User's Manual
o From the main menu, at the "File(s)" prompt, you can enter:
- a list of files to be displayed. Example: 3,1,5-7,17-14
will display the files 3,1,5,6,7,17,16,15,14 in that order.
- "m" to change the display mode
- "d" to select a different directory/different group of files
- "o" to change the user selectable options
- "q" to quit and go back to DOS.
o The default amount of time for which each picture in the list is displayed
is 10 seconds. However, pressing the return key at the end of a picture
forces moving on to the next picture. Pressing the ESC key at the end of
a picture cancels the whole list. Pressing the ESC key while the picture
is being drawn aborts that one picture.
o The amount of time that each picture is displayed can be set from the
"Options" menu.
o The default display mode is EGA 640x350 16-color.
o When you use option "d", make sure to specify the directory AND the
files to be listed. (Example: gifpics\*.* or \picdir\*.gif). If
you end a directory with a "\", then all files that match "*.gif" in
that directory will be listed.
o The default is to automatically scale the picture in the horizontal and
vertical directions so that it fits on the screen. When the picture is
larger than the screen, you lose some resolution when this is done. You
can disable this from the "Options" menu.
o VUGIF is entirely menu driven and has no command line options.
o You can run VUGIF in a PRE-PROGRAMMED mode where it will go through a
display session with no keyboard input. To do this, go through a manual
session and write down all keystrokes till you quit VUGIF back to DOS
(important). Avoid using the ESC key or the return key during picture
display when you do this. Then create a file containing these keystrokes.
To do this, type:
copy con: vugif.inp <return> (name vugif.inp is just an example)
Enter the keystrokes you wrote down and then type a <CTRL>Z to create the
file called vugif.inp. A text editor (ex. edlin) may also be used to
create such a file. This file may then be used to run VUGIF in the
PRE-PROGRAMMED mode by typing
vugif <vugif.inp
o If the program does not work with your display board, you may need to load
any software drivers (BIOS emulators, int 10h drivers, RAM BIOS drivers)
that come with it.
o EXTENDED VIDEO MODES: These are non-standard (i.e. not CGA, MDA,
Hercules, EGA or VGA) video modes that your graphics card may support.
They are dependent on your graphics card. Refer to your graphics card
manual to see what additional modes are supported. Only VGA type extended
modes with either 16 or 256 colors out of a palette of 262,144 colors may
be used. There must be a video mode number associated with the extended
mode. These extended modes must be supported by the BIOS (ROM BIOS in the
card or BIOS drivers/int 10h drivers that have been loaded in RAM). Not
all cards support this.
To use an extended mode, you will need to know the mode number, the
no. of columns, no. of rows, and the no. of colors for the mode. Refer
to the manual for your graphics card.
Display will be extremely SLOW in the extended modes because of the use of
BIOS. Contact OFFE to determine if fast VUGIF drivers are available for
your card (available to registered users).
