Hi, I'm trying to, in addition to all the other things on my cairo surface, pull some images in from .png files. I've googled, I've looked in the docs, but there isn't any way I can see to load a .png file into a surface. The best I can find is withImageSurfaceFromPNG, but I can't make it work. The C guys can do: image = cairo_image_surface_create_from_png("blah.png"); and then: cairo_set_source_surface(cr, image, 10, 10); cairo_paint(cr) I tried playing around with unsafePerformIO but that just gets me into: /build/buildd/cairo-1.6.0/src/cairo-surface.c:382: cairo_surface_reference: Assertion `((*&(&surface->ref_count)->ref_count) > 0)' failed. Are any gtk2hs people around who can throw me in the right direction? Sincerely, Rafal Kolanski.
