gl_putboxmask (3)
copy a masked pixmap to a rectangular area
SYNOPSIS
#include <vgagl.h>
void gl_putboxmask(int x , int y , int w , int h , void * dp );
DESCRIPTION
Copy the contents of a memory buffer
dp
to a rectangular bitmap at position
( x , y )
with size
( w , h ).
This function works like
gl_putbox ,
but does not write pixmap pixels of color zero. If the same pixmap is used often
you should consider using the faster
gl_putboxmaskcompiled (3).
Pixmaps are in row-major order. The source pixmap memory has the size
w * h *
BYTESPERPIXEL .
