Hi all, I'm doing some work on eyetracking data, and am interested in storing probability maps and other stuff in PNG images. As a start, I'm using the alpha channel to store a gaze map. I'm worried about losing precision when doing group stats, so I'd like to use 16 bits per band.
>From what I can tell from reading past list entries and initial source-diving, the PngImagePlugin doesn't support writing 48 or 64-bit images. I'm less clear on this, but it seems that most of the infrastructure is in-place to support them -- at least, the raw modes for RGBA;16B and RGB;16B are defined and seem to get used when reading. What I can't figure out, though, is how (or whether) those options get transferred over to the Image object that gets created. So... before I go too very far down this rabbit hole, I'm wondering if anyone knows: is this something I can make work by hacking PngImagePlugin, or would I need to delve further into the workings of PIL? Thanks a million, -Nate _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
