cairo_pattern_t* go_image_create_cairo_pattern ( GOImage * image )

go_image_create_cairo_pattern:

a GOImage.

returns: a cairo_pattern usable for cairo_set_source.

Note: this function has lifespan issues. The resulting pattern in only valid until (a) a pixbuf is set for the, or (b) a pixbuf is _read_ from the image. In either of these cases, the pattern must have been destroyed beforehand. In particular, if the pattern has been attached to a surface, that surface must either be finished itself, or have had a new pattern attached. See #632439.
