NAME
xviewgl - display GRASP library files under X11
SYNTAX
xviewgl [-d del] [-f] [-F] [-i] [-s] [-t] [-x n] [-y n] file [script]
Where file is either the name of a directory containing an unpacked
GRASP library, the name of a GRASP library file ending in ".gl", or
the name of a GRASP script ending in ".txt". If file is a directory
or GRASP library name, you may specify script , the name of a script
to use within the library or directory. The default is to use the
first script encountered.
DESCRIPTION
Xgl is an X11-based viewer for GRASP libraries. GRASP is an animation
package popular on IBM PCs. It is a near-complete implementation of
GRASP V1.10 , with many features from later versions of GRASP.
In order to see the colors properly, you may need to set input focus
to xviewglusing the -i option. The xviewgl window will accept the
following input in addition to any requested by GRASP files: <space>
will pause the animation, <esc> will exit xviewgl , and any other key
will break out of a single delay.
OPTIONS
-d del
Sets minimum delay to del hundredths of a second. This
option is useful for viewing files designed for viewing on slow
PCs.
-F Attempts to play friendly with the colormap. Colors
are allocated from the highest number down so as to
minimize the diruption of other applications' colors.
-f Attempts to "fix up" the aspect ratio according to the
screen type.
-i Install colormap.
-q Quiet mode. Don't beep for sound effects.
-s Synchronize display. For debugging.
-t Trace. Display each line before executing.
-x n These options allow you to specify x and y scaling factors.
-y n Only integer values are allowed.

KNOWN BUGS
Monochrome support is latent, but I don't have a monochrome system, so
I can't get it working. Feel free to hack around in windows.c to try
to get it going.
I am looking for information on .DFF and BSAVE images. Any help or
specifications may lead to my adding support for them.
I am also interested in adding support for any of the standard
variables GRASP supports, and for info on commands (like DLOAD and
PUTDFF) which I don't understand. Any documentation or command
descriptions would be helpful. (I have seen the GRASP v1.10 docs, so
I don't need them...)
