The following does it:
int img_width = gdk_pixbuf_get_width(pixbuf);
int img_height = gdk_pixbuf_get_height(pixbuf);
cairo_surface_t *surface
= cairo_image_surface_create_for_data(gdk_pixbuf_get_pixels(pixbuf),
CAIRO_FORMAT_ARGB32,

width = gdk_pixbuf_get_width (pixbuf);
height = gdk_pixbuf_get_heigh

Hi Chen,
For the application that you described, using a canvas doesn't give you much
and you can just as well create a cairo context and draw on the image
directly. But there are a few things that you should be aware of:
- Drawing overlays on av full realtime speed is going to take a lot of
Hello!
I'm working on MT application, which perform some tasks in separated
threads. My application also use GTK+ and it should work on Windows, so I
need to deal somehow with running all functions, which change GUI from one
thread.
I run one thread with GTK's main loop and i want to implement ne
