does not seem to work as expected

I gave this code a spin but I wasn't able to make it work. I tried to display one image using lsix and while it perfectly works with xterm -ti vt340, it generated a bunch of the following X errors with the latest commit. What am I doing wrong? Thanks for the awesome work!
