- update to version 0.20220715.0 * Development moved to gitlab: https://gitlab.com/drj11/pypng * If you pass an empty file to PyPNG it now raises the builtin Python exception EOFError. This should make it easier to diagnose empty file problems separately from genuine format errors (which use png.FormatError). This is a slightly breaking change to the API. * New prirowpng tool to join PNG images in a row left-to-right (old internal pipcat tool). * New pricolpng tool to join PNG images in a column top-to-bottom. * Support for plain PGM files (magic number P2) added to pripamtopng. * New priplan9topng tool to convert from Plan 9 image format to PNG. In reality this has been lurking in the codebase for years, but has recently been converted to Python 3. The author has only a limited collection of Plan 9 images, which limits the testing that can be done. The author welcomes bug reports for Plan 9 images. * The priplan9topng tool has an even more experimental option --font which converts Plan 9 subfont files to a sequence of PNG files. - release 0.0.21 * Support for Python 2 is dropped. * Python 3.5 and onwards are supported. * Some of the ancillary tools are modified to work on Python 3. * Installs via wheel files. * prichunkpng command line tool now has some new options to add * chunks: --iccprofile to add a iCCP chunk (ICC Profile); --physical to add a pHYs chunk, specifying the intended pixel size; --sigbit to add a sBIT chunk, specifying the encoded significant bits; --transparent to add a tRNS chunk, specifying the transparent colour. * priditherpng command line tool standardised and converted to Python 3. * pripngtopam tool now has a --plain option to output plain PGM and PPM formats. The topam part of the name is a bit of a misnomer: when possible (L and RGB PNG files) the tool will output either a PGM (grey) or a PPM (RGB) file. Essentially all tools that can process a PAM file can also process a PGM or a PPM file. PAM files cannot be plain so using the option will raise an error in the case where a true PAM file is written. * Better error messages when you write the wrong number of rows. (Slightly experimentally) running the png module as a command line tool, with python -m png, will report the version and file location of the png module. - remove pr_106.patch - remove pypng-pr104-py39.patch OBS-URL: https://build.opensuse.org/request/show/1096534 OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-pypng?expand=0&rev=19
