The Gdk functions to create bitmaps from data require xbm or xpm data. (For example gdk_bitmap_create_from_data ()). Why do I not see anything to create a bitmap from a (b&w) .png image? I've used the pixbuf library before, using gdk_draw_pixbuf() but the program I am working on uses a GdkBitmap * mask to draw in the following fashion:
gdk_gc_set_clip_mask (gc, mask); gdk_gc_set_clip_origin (gc, x, y); gdk_draw_rectangle (pixmap, gc, TRUE, x, y, width, height); gdk_gc_set_clip_mask (gc, NULL); /* Removes clip mask */ I don't understand the issues here; I want the application to let the user select a (small) rectangular area in the .png image for use in as the GdkBitmap *mask in the above code. Anyone with a wider view on this stuff? Help would be much appreciated!
