NAME

6       gl_putboxmask - copy a masked  pixmap to a rectangular area
7

SYNOPSIS

10       #include <vgagl.h>
11
12       void gl_putboxmask(int x, int y, int w, int h, void *dp);

DESCRIPTION

16       Copy  the  contents  of  a  memory buffer dp to a rectangular bitmap at
17       position (x, y) with size (w, h).
18
19       This function works like gl_putbox, but does not write pixmap pixels of
20       color  zero. If the same pixmap is used often you should consider using
21       the faster gl_putboxmaskcompiled(3).
22
23       Pixmaps are in row-major order. The source pixmap memory has the size w
24       * h * BYTESPERPIXEL.
