gl_putboxmask(3)              Svgalib User Manual             gl_putboxmask(3)


NAME

       gl_putboxmask - 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.
