Hi, How should the "format" of a DRI2 buffer be determined?
http://www.x.org/releases/current/doc/dri2proto/dri2proto.txt DRI2ATTACH_FORMAT { attachment: CARD32 format: CARD32 } The DRI2ATTACH_FORMAT describes an attachment and the associated format. 'attachment' describes the attachment point for the buffer, 'format' describes an opaque, device-dependent format for the buffer. xorg-server-1.7.7/hw/xfree86/dri2/dri2ext.c If it's opaque, how does a user or library know what bytes are red/green/blue so that you can draw a line in the right colour? I want to bit-bang pixels in an X app on the local machine, without any intervening GL drivers. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
