Note that djvu would compress things very nicely. A full page 300dpi magazine color page that may be 25MB uncompressed will compress down to 40K-80K or so and be very legible, much more so compared a similar sized jpeg compressed image.
The current OSS djvu library is GPL but as far as I know the original AT&T patent on the djvu technology has expired. If anyone wants to reimplement it with a more permissive license! The benefit is that there are a lot of existing djvu encoded documents. [Note: if anyone does decide to reimplement djvu, they should not just take my word for it but verify that the djvu patent(s) have indeed expired] > On Jan 29, 2022, at 6:08 AM, ibrahim via 9fans <9fans@9fans.net> wrote: > > A great amount of this size is caused by hand written sample solution scans > for past exams provided as 300dpi images (png or ppm).
