The IO documentation doesn't seem to be very good. It explains how plugins work but it's scarce on examples e.g. on how to export jpeg image with a specified compression level. The IO API docs don't give much detail either. Some details can be found in the docs for external.tifffile but it takes some searching to find it. For PIL the only way to figure out how to use it seems to be looking at the source code - no modern docs as far as I can tell (did I fail to use Google properly?).

Any thoughts?

Best wishes,
