It reads and writes +PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per +pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA, +LA (greyscale with alpha) with 8/16 bits per channel; colour mapped +images (1/2/4/8 bit). Adam7 interlacing is supported for reading and writing. +A number of optional chunks can be specified (when writing) and +understood (when reading): tRNS, bKGD, gAMA. + +PyPNG is not a high level toolkit for image processing (like PIL) and does not +aim at being a replacement or competitor. Its strength lies in fine-grained +extensive support of PNG features. It can also read and write Netpbm PAM +files, with a focus on its use as an intermediate format for implementing +custom PNG processing.") + (license license:expat))) |
