If you're working with a cairo image surface and your ImageMagick code
doesn't change the image's dimensions, it should be possible to use
something like the following Magick++ pseudo-code:

Blob blob(cairo_image_surface_get_data(surface));
Image image;

Then manipulate the Image without needing cairo to re-read the data.
