Actually this probably would be pretty fast. I haven't worked with BMP
images in quite a while but iirc the format is quite simple.

The to_blob and from_blob methods are actually very similar to the
write and read methods. The only difference is that the blob methods
read from/write to memory and the write/read methods operate on files.
