Update mostly of interest for developers, centered on presumably more clear docs. In general, version is quite stable, and raise exceptions only when something really stupid happens, like trying to write negative colors etc.

PyPNM for Python 3.4 updated PyPNM 2.21.3.4.post4 as well.

PyPNM update mostly centered on docstrings turning to a more helpful ReST-compliant form.

PyPNM upgraded to version 2. Upgrade includes numerous internal changes aimed to save resources, i.e.:

• using mmap instead of direct reading;
• using generators wherever possible.

Module input and output types and structures remain the same as for 9 May "Victory", making ver. 2 fully interchangeable with ver. 1.

PyPNM upgraded to version 2. Upgrade includes numerous internal changes aimed to save memory, namely:

• using mmap instead of direct file reading;
• using generators wherever possible (sometimes even where memory savings are minimal, but why not, раз пошла такая пьянка - режь последний огурец!)

Module input and output types and structures remain the same as for 9 May "Victory", making ver. 2 fully interchangeable with ver. 1. PyPNM documentation also remain unaltered and valid.

Update mostly related to Viewer.py and includes minor GUI update and, most interesting, command line support. Now you may use commans like

python viewer.py filename.ppm

to open PPM, PGM and PBM image files.

This release is main version (Python 3.11 and above); corresponding files for Python 3.4 and above are available at 2.20.4.34 tag.

NOTE: This release contain a workaround for Python deprecations, which affected previous release under some circumstances. Previous release of 2.20.4.20 to be deleted.

Maximum compatibility branch .py34 major update. Forced 8 bit preview for 16 bit images when running under old versions of Python. Supposedly perfect in terms of compatibility.

Optimized main version. Does not contain compatibility workarounds from maximum compatibility branch, and therefore works faster.

Maintenance release, more attempts at RAM cleanup.

New version trying to reduce resource load.

For previewing with list2bin LA and RGBA images may be rendered against chessboard background (optional, controlled by new show_chessboard: bool. Default is False for backward compatibility.
