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 xviewgl using 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.
 −FAttempts to play friendly with the colormap.  Colors
are allocated from the highest number down so as to
minimize the diruption of other applications’ colors.
 −fAttempts to "fix up" the aspect ratio according to the
screen type.
 −iInstall colormap.
 −q     Quiet mode.  Don’t beep for sound effects.
 −sSynchronize display.  For debugging.
 −tTrace.  Display each line before executing.
 −x nThese options allow you to specify x and y scaling factors.
−y nOnly 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...)
