(description
|
||||
"The PyPNG module implements support for PNG images. 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.")
