.SH "DESCRIPTION" 
.PP 
This manual page documents briefly the 
\fBvisualinfo\fR  command. 
.PP 
\fBvisualinfo\fR is a small utility that displays all available visuals, 
aka. pixelformats, in an OpenGL system along with renderer version 
information. It shows a table of all the visuals that support OpenGL 
along with their capabilities. The format of the table is similar to 
that of glxinfo on Unix systems: 
 
 
.IP "visual" 10 
~= pixel format descriptor 
.IP "id" 10 
= visual id (integer from 1 \- max visuals) 
.IP "tp" 10 
= type (wn: window, pb: pbuffer, wp: window & pbuffer, bm: bitmap) 
.IP "ac" 10 
= acceleration (ge: generic, fu: full, no: none) 
.IP "fm" 10 
= format (i: integer, f: float, c: color index) 
.IP "db" 10 
= double buffer (y = yes) 
.IP "dw" 10 
= swap method (x: exchange, c: copy, u: undefined) 
.IP "st" 10 
= stereo (y = yes) 
.IP "sz" 10 
= total # bits 
.IP "r" 10 
= # bits of red 
.IP "g" 10 
= # bits of green 
.IP "b" 10 
= # bits of blue 
.IP "a" 10 
= # bits of alpha 
.IP "axbf" 10 
= # aux buffers 
.IP "dpth" 10 
= # bits of depth 
.IP "stcl" 10 
= # bits of stencil 
.SH "OPTIONS" 
.PP 
A summary of options is included below. 
.IP "\fB-h\fP           \fB\-\-help\fP         " 10 
Print help and exit. 
.IP "\fB-display \fIdisplay\fR\fP         " 10 
Allows specifying an X display. 
.IP "\fB-visual \fIid\fR\fP         " 10 
Allows specifying a specific X visual.
