Use zlib-ng instead of zlib by nulano · Pull Request #8500 · python-pillow/Pillow

nulano · 2024-10-25T19:20:37Z

Alternative to #8495 .

Changes proposed in this pull request:

Replace zlib with zlib-ng built with CMake in Windows builds. Building our own zlib-ng allows us to use the latest release since the zlib-ng 2.2.2 release is missing the x86_64 Windows build.

Add a flag to PIL.features for zlib-ng. python3 -m PIL.report now looks like this:

I took inspiration from #8495 (comment) to make a benchmark with multiple compression values. It seems that zlib-ng usually produces a slightly larger file but in much less time during compression.

Looking at the build logs, zlib-ng seems to have been properly detected by webp, libtiff, libpng, and freetype.

TODO:

Run the test suite on Windows arm64. I can use a borrowed M2 MacBook, but I won't have access to it at least until Monday.
We should also update the Linux...
...and macOS builds for consistency if we decide that we do want to go with zlib-ng.

dofuuz · 2024-10-26T01:19:30Z

zlib-ng v2.2.2 x86_64-compat was not released because of CI test error. It'll be released at next version again.
So, downloading pre-built binary is still a valid way.

Anyway, building with CMake is also a fine solution. I'll follow Pillow devs' decision and close my PR #8495 when it's decided.

Here's a chart of the write times for different compression levels and images:

hopper.png: 1.3.1 zlib-ng (red) is much better than 1.3.1 (blue)
effect_spread.png: 1.3.1 zlib-ng (green) is noticeably better than 1.3.1 (yellow)

Summary: zlib-ng is much faster.

And file sizes:

compression level 0: same for all
compression level 1: 1.3.1 zlib-ng is much worse than 1.3.1
compression level 2-3: 1.3.1 zlib-ng is slightly better than 1.3.1
compression level 4-6: 1.3.1 zlib-ng is even more slightly worse than 1.3.1
compression level 7-9: about the same, zlib-ng ever so slightly better than 1.3.1

Summary: zlib-ng has same file sizes for compression level 0 and bigger files for compression level 1, but if you care about size, any higher compression level gives more or less the same file size (and zlib-ng is faster).

If zlib-ng creates zlibstatic.lib by default, then wouldn't it seem helpful to detect that in setup.py, in case a user had built it themselves? nulano#44

Oh, is the concern that zlib-ng might have been built without --zlib-compat?
