A bitmap is a pixrect with only two possible colors. It is represented by a triple (w,h,s) where w is the width, h the height, and s the string of bits (type char *) of the bitmap.

Operations

  char * W.create_bitmap(int w, int h, char** xbm);
  char * W.put_bitmap(double x, double y, char* bmap, color c);
  char * W.put_bitmap(point p, char* bmap, color c);
  char * W.delete_bitmap(char* bmap);

Example

#include <LEDA/graphics/window.h>
#include <LEDA/graphics/bitmaps/leda_icon.xbm>

using namespace leda;

int main()
{
  window W(400,400);
  W.display();

  W.set_bg_color(yellow);
		
  char * bm = W.create_bitmap(leda_icon_width,leda_icon_height,leda_icon_bits);
  //leda_icon_width, leda_icon_height, leda_icon_bits
  //are defined in 	<LEDA/bitmaps/leda_icon.xbm>

  point p;
  while (W>>p) W.put_bitmap(p.xcoord(),p.ycoord(),bm,blue);
		
  W.del_bitmap(bm);

  W.screenshot("bitmaps");
		
  return 0;
}
