DESCRIPTION
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
