Prusa MINIs new firmware is using QOI image format instead of PNG

[dmyers7]

In the new Prusa Mini Alpha firmware, implementing input shaping, Prusa has switched to a QOI image format. Can the plugin be update to detect the format and continue showing the thumbnails? Does the pixel count matter?

I'm not familiar with that image format, but assuming pillow can read it I don't see any reason changes couldn't be implemented. Would need to know if they are flagging it differently somehow or not, can you share a sliced file?

Appears to be available in Pillow version 9.5.0+. https://pillow.readthedocs.io/en/stable/handbook/image-file-formats.html#qoi, currently no restriction on Pillow version required by the plugin, so would need to add that minimum requirement in setup.py.

Yup, looks like they do call it out:
"; thumbnail_QOI begin 200x240 13184"

added in the above commit and available in version 1.0.3rc3. You can change your release channel in OctoPrint's software update settings for the plugin to Release Candidate and upgrade when prompted to test it out and validate.

Verified and validated. It recovered images in QOI format on files not previously processed and automatically on files freshly uploaded. Thank you very much.
