Subject: PNG images sometimes get larger
Download (untitled) / with headers

Sometimes when we read a PNG and write it out it becomes larger. This could be due to: - lower compression setting - change in image format (paletted to direct color) Hoping for a sample that demonstrates the problem.

Currently Imager always imports PNG files as RGB(A), even if the source is paletted. Imager's PNG code should: - import paletted as paletted - write paletted as paletted - read/write large sample PNG files - support more PNG metadata - support bi-level if PNG does
Spent some time on this, but I think Imager needs psamp()/psampf() to make this vaguely efficient.
