[16:32:21] <rominf> Hi all. I've asked this question on image-sig@python.org but it seems to be dead.

[16:32:29] <rominf> I need to implement something like RDP.

[16:32:31] <rominf> To minimize size of packages I decided to send full image of remote desktop once, then send just diffs (something like very primitive video encoding).

[16:32:39] <rominf> I suppose I need something like (pseudocode):

[16:32:58] <rominf> # on sender

[16:32:59] <rominf> d = diff(

[16:33:16] <rominf> d = diff(base, new)

[16:33:20] <rominf> send(d)

[16:33:25] <rominf> # on receiver

[16:33:30] <rominf> d = receive()

[16:33:38] <rominf> new = patch(base, d)

[16:33:50] <rominf> I found functions `difference`, `add` and `subtract` in `ImageChops` module, but I suppose they provide different functionality.

[16:33:54] <rominf> Are there functions in Pillow that I've just described?
