My question wasn't about how to write a GIL image to a file, it was
about the most efficient way to serialize it to a boost archive. The
class that owns the GIL image in my case also has other state and the
entire class instance needs to be serializable. Obviously I can get the
raw data and serialize that out, but when reading in from the archive
wouldn't I have to read it in to a temporary buffer and then use that
buffer to reconstruct the GIL image? I'd rather not perform extra
copies of pixel data like that if I don't have to.
