NAME¶
gl_compileboxmask - compress a masked bitmap
SYNOPSIS¶
#include <vgagl.h>
void gl_compileboxmask(int w, int h, void
*sdp, void *ddp);
DESCRIPTION¶
Convert the rectangular masked bitmap of size (
w,
h) at
sdp
to a compressed format that allows faster drawing, which is stored at
ddp. Allocating
w *
h bytes for the compiled version is
usually enough; an upper limit should be (
w + 2) *
h.
Compiled bitmaps are only supported in linear 256 color modes.
