Hi, every one,
I had question about gdk-pixbuf. I want to show some bmp files and I completed the work by following steps:
1. create a pixbuf using gdk_pixbuf_new_from_file()
2. draw that pixbuf using gdk_draw_pixbuf()
it works fine, but I noticed that the bmp files all have background color (pink), and I want to hide it.
I know it has something to do with mask, but I don't which function show I use, could it be gdk_pixbuf_render_threshold_alpha(), or gdk_pixbuf_render_pixmap_and_mask()? and how to use it? Is there any one who can help me? many thanks!
