visualinfo displays GL extension and visual info
visualinfo [-display display] [-visual id]
This manual page documents briefly the
visualinfo command.
visualinfo 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:
"visual"
~= pixel format descriptor
"id"
= visual id (integer from 1 - max visuals)
"tp"
= type (wn: window, pb: pbuffer, wp: window & pbuffer, bm: bitmap)
"ac"
= acceleration (ge: generic, fu: full, no: none)
"fm"
= format (i: integer, f: float, c: color index)
"db"
= double buffer (y = yes)
"dw"
= swap method (x: exchange, c: copy, u: undefined)
"st"
= stereo (y = yes)
"sz"
= total # bits
"r"
= # bits of red
"g"
= # bits of green
"b"
= # bits of blue
"a"
= # bits of alpha
"axbf"
= # aux buffers
"dpth"
= # bits of depth
"stcl"
= # bits of stencil
A summary of options is included below.
"-h
Print help and exit.
