ggiDrawBox3

Usage

#include <ggi/ggi.h>
int ggiDrawBox(ggi_visual_t vis, int x, int y, int w, int h);
int ggiPutBox(ggi_visual_t vis, int x, int y, int w, int h, const void *buf);
int ggiGetBox(ggi_visual_t vis, int x, int y, int w, int h, void *buf);

Overview

Draw, put, or get a rectangle at (x, y), extending w pixels in the positive x direction and h pixels in the positive y direction.

The buf parameter in Get/Put functions points to a buffer from which the pixels will be read, or to which they will be written (it must be correctly allocated), respectively. See ggiPackColors(3) and ggiUnmapPixel(3) functions for details on how to deal with pixels.

Return value

All three functions return 0 to indicate success.
