C glXChooseVisual GLX_RGBA If present, only TrueColor and DirectColor visuals are considered. Otherwise, only PseudoColor and StaticColor visuals are considered. GLX_DOUBLEBUFFER If present, only double-buffered visuals are considered. Otherwise, only single-buffered visuals are considered. GLX_STEREO If present, only stereo visuals are considered. Otherwise, only monoscopic visuals are considered. GLX_AUX_BUFFERS Must be followed by a nonnegative integer that indicates the desired number of auxiliary buffers. Visuals with the smallest number of auxiliary buffers that meets or exceeds the specified number are preferred. GLX_RED_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, the smallest available red buffer is preferred. Otherwise, the largest available red buffer of at least the minimum size is preferred. GLX_GREEN_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, the smallest available green buffer is preferred. Otherwise, the largest available green buffer of at least the minimum size is preferred. GLX_BLUE_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, the smallest available blue buffer is preferred. Otherwise, the largest available blue buffer of at least the minimum size is preferred. GLX_ALPHA_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, the smallest available alpha buffer is preferred. Otherwise, the largest available alpha buffer of at least the minimum size is preferred. GLX_DEPTH_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, visuals with no depth buffer are preferred. Otherwise, the largest available depth buffer of at least the minimum size is preferred. GLX_STENCIL_SIZE Must be followed by a nonnegative integer that indicates the desired number of stencil bitplanes. The smallest stencil buffer of at least the specified size is preferred. If the desired value is zero, visuals with no stencil buffer are preferred. GLX_ACCUM_RED_SIZE Must be followed by a nonnegative minimum size specification. If this value is zero, visuals with no red accumulation buffer are preferred. Otherwise, the largest possible red accumulation buffer of at least the minimum size is preferred. Chapter 3 47
