The Kobo is probably going to have an *extremely* hard time dealing with anything image-related on its own at anything better than a snails pace, especially given the native resolution on the average midrange smartphone.

If you go this route, better have the source preprocess the image as much as possible, so that the Kobo ends up having to do almost zero work besides dumping that to the framebuffer verbatim (i.e., match the target pixel format, ideally after having switched to 8bpp on the Kobo to save some bandwidth).

(The examples in the Python FBInk bindings have some musings about that sort of things).
