This would allow users to generate favicons using thumbor.
The optimal favicon should have:
16x16, 16-bit (256) colors
16x16, 32-bit colors
32x32, 16-bit (256) colors
32x32, 32-bit colors
48x48, 16-bit (256) colors
48x48, 32-bit colors
64x64, 16-bit (256) colors
64x64, 32-bit colors
Just so I can remember later, it seems that we can do it using libpng in python:
Should be easy to figure out how to write all those formats.
Not sure this is doable... From what I gathered we would have to output many images in the same image. We won't be doing this ticket for now. We can always reopen it later if the team decides to implemente it.
