I don't know exactly what a resource file is, nor how it works, but
cairo does provide a function:

cairo_surface_t *
cairo_image_surface_create_from_png_stream (cairo_read_func_t   read_func,
                                            void                *closure)

to which you can provide a custom callback function to do whatever
reading you might need to do, (to then supply the png data to cairo).

I hope that helps, and that you have fun with cairo.
