Optimizer for PNG Files that can also insert or delete specified Chunks
pngcrush is an excellent batch-mode compression utility for PNG
images. Depending on the application that created the original PNGs, it can
improve the file size anywhere from a few percent to 40% or more (completely
losslessly). The utility also allows specified PNG chunks (e.g. text comments)
to be inserted or deleted, and it can fix incorrect gamma info written by
Photoshop 5.0 as well as the erroneous iCCP chunk written by Photoshop 5.5.
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
