Your change 9c66b09950cf2db50eb6d818656a268ef750bfe6 broke doc-view.el
and the pdf-tools package whose author already filed bug#37874 for the
issue.

Could you have a look?  If the image functions stay returning pixel
values that's ok but Andreas and I will need to adapt pdf-tools and
doc-view.el accordingly.

Bye,
Tassilo
