gl_putboxpart(3) copy a partial pixmap to a rectangular area


#include <vgagl.h>

void gl_putboxpart(int x, int y, int w, int h , int bw, int bh, void *dp , int xo, int yo);


Copy the contents of a memory buffer dp to a rectangular bitmap at position (x, y) with size (w, h).

However, only a part of size (bw, bh) starting at offset (xo, yo) in the pixmap is copied.

Pixmaps are in row-major order. The source pixmap memory has the size w * h * BYTESPERPIXEL.
