This documents the protocol: <a href="http://gitweb.freedesktop.org/?p=xorg/proto/renderproto.git;a=blob_plain;f=renderproto.txt"> http://gitweb.freedesktop.org/?p=xorg/proto/renderproto.git;a=blob_plain;f=renderproto.txt</a> The API in <a href="http://gitweb.freedesktop.org/?p=xorg/lib/libXrender.git;a=blob;f=include/X11/extensions/Xrender.h"> http://gitweb.freedesktop.org/?p=xorg/lib/libXrender.git;a=blob;f=include/X11/extensions/Xrender.h</a> follows the protocol fairly closely. > Are there any new books about programming under X? ( newer as > 1993...) Not that I am aware of. I generally prefer to read source code (as it is always more accurate).
