Hello,

I want to draw using Fl_Offscreen, doing something like:

{
  Fl_Offscreen oscr = fl_create_offscreen(120, 120);

  fl_begin_offscreen(oscr);
  fl_color(FL_BLACK);
  fl_rectf(0, 0, 120, 120);
  fl_color(FL_WHITE);
  fl_rectf(-10, -10, 100, 100);
  fl_end_offscreen();
 
  // print offscreen color at (10, 10)
  fl_delete_offscreen(oscr);
}

Two questions:

1) At the end of this code I want check the color of a given point. How can I do that?
2) I write to outside the pixmap (fl_rectf(-10, -10, 100, 100)), is that ok ?

Best regards
Håvard
