NAME

SYNOPSIS

10       #include <vgagl.h>
11
12       void gl_compileboxmask(int w, int h, void *sdp, void *ddp);

DESCRIPTION

16       Convert  the  rectangular masked bitmap of size (w, h) at sdp to a com‐
17       pressed format that allows faster drawing,  which  is  stored  at  ddp.
18       Allocating  w  * h bytes for the compiled version is usually enough; an
19       upper limit should be (w + 2) * h.
20
21       Compiled bitmaps are only supported in linear 256 color modes.
