Re: How to dump a gnome canvas in a file ?

[Alexandru Csete <alexc phys au dk>]

If you use Gnome 1.2 or 1.4, you can use GdkImlib to grab and save the
contents of any widget that has it's own window:

GdkImlibImage *img =
gdk_imlib_create_image_from_drawable(canvas->window,NULL,0,0,width,height);
gdk_imlib_save_image(image, filename, info);

In Gnome 2 you can do the same using the gdk-pixbuf library (I did not
try this, but I've seen it in the API reference).

You should be aware of that these functions make a 'real' screenshot,
meaning that if part of your canvas is covered by another window it will
be included in the resulting image.
