Running PNGs through zopflipng makes them smaller, with no drawbacks. This patch was done with zopflipng version 1.0.1 with the -m option, and decreases the in-tree total size size of all *.png by almost 100KiB. $ find -name "*.png" | xargs du -bc | tail -n 1 # before 291101 total $ find -name "*.png" | xargs du -bc | tail -n 1 # after 194639 total |

Hi, The idea is interesting, but IMO it would be more efficient to contribute to Sphinx, so all documentations will benefit of smallest pictures. There is a similar tool for JPEG. Victor |

Sure, I plan to suggest this to sphinx as well. One corresponding tool for JPEGs is jpegoptim and its --strip-all option, but there is only ./Mac/BuildScript/resources/background.jpg in the cpython source tree (which despite of the .jpg extension appears to be a PNG file so I don't want to touch that stuff), plus ./Lib/test/imghdrdata/python.jpg which isn't worth a patch alone :) |
