• CRX-24[Z] Device-Dependent Information Supported Visuals The following visuals are supported: • Class PseudoColor Depth 8 Layer Image supports DBE and MBX hardware double-buffering • Class PseudoColor Depth 8 Layer Overlay supports DBE and MBX software double-buffering • Class DirectColor Depth 12 Layer Image supports DBE and MBX hardware double-buffering • Class TrueColor Depth 12 Layer Image supports DBE and MBX hardware double-buffering • Class DirectColor Depth 24 Layer Image doesn't support DBE and MBX double-buffering • Class TrueColor Depth 24 Layer Image doesn't support DBE and MBX double-buffering Supported Screen Options The following Screen Options are supported: • CountTransparentInOverlayVisual • SwapBuffersOnVBlank • ImageTextViaBitMap • CRX24_FULL_DEFAULT_VISUAL • EnableIncludeInferiorsFix CRX-24[Z] Transparent Overlay Visuals The default number of colormap entries in the overlay visual for the CRX-24[Z] is 255. Entry 255 is excluded because its value is hard-coded to transparent (that is, show the image planes). This may have the following two consequences for X11 applications running in the overlay planes (the default visual): • Clients attempting to allocate 256 entries do not have their request granted. • Clients requesting (via XAllocNamedColor) the rgb.txt value of "Transparent" are not returned entry 255. This default behavior can be changed by setting the CountTransparentInOverlayVisual screen option. Page 55 Graphics Administration Guide for HP-UX 10.20
