gl_compileboxmask3vga

Compress a masked bitmap

Part of gl_compileboxmask(3).

Usage

#include <vgagl.h>

void gl_compileboxmask(int w, int h, void *sdp, void *ddp);

Overview

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.
