4.30.0

Changes (Release 4.30.0)

Summary (pypdfium2)

Backported bug fixes / corrections from current development branch to preferably leave v4 in a clean state.

• Fixed blunder in PdfImage.extract() producing an incorrect output path for prefixes containing a dot. In the extract-images CLI, this caused all output images of a type to be written to the same path for a document containing a non-extension dot in the filename.
• XFA / rendering CLI: Fixed incorrect recognition of document length. pdf.init_forms() must be called before len(pdf).
• Made get_text_range() allocation adapt to pdfium version, as FPDFText_GetText() has been reverted to UCS-2. (See v4.28 changelog for background.)
• Updated workflows to include both macos-13 and macos-14 in test matrices because v13 is Intel and v14 ARM64 on GH actions. Removed python 3.7 testing because not supported anymore on macos-14 runners.

4.28.0

Changes (Release 4.28.0)

Summary (pypdfium2)

• get_text_range(): Fixed a buffer size regression introduced in v4.26.0, caused by an unexpected behavior change in pdfium (thanks @elonzh for the bug report, {issue}298). Since that change, it is not possible anymore to tell the exact amount of memory needed, so we have to allocate for the worst case. Therefore, while this problem persists, it is recommended to instead use get_text_bounded() where possible.

4.27.0

Changes (Release 4.27.0)

Summary (pypdfium2)

• Added ability to define $CTYPESGEN_PIN when building sdist via ./run craft pypi --sdist, which allows to reproduce our sdists when set to the head commit hash of pypdfium2-team/ctypesgen at the time of the build to reproduce. Alternatively, you may patch the relevant pyproject.toml entry yourself and use PDFIUM_PLATFORM=sdist python -m build --sdist as usual.
• Set up Dependabot for GH Actions. Updated dependencies accordingly.

4.26.0

Changes (Release 4.26.0)

Summary (pypdfium2)

• Pin ctypesgen in sdist to prevent reoccurrence of {issue}264 / {issue}286. As a drawback, the pin is never committed, so the sdist is not simply reproducible at this time due to dependence on the latest commit hash of the ctypesgen fork at build time.

4.25.0

Changes (Release 4.25.0)

Summary (pypdfium2)

• Removed multiprocessing from deprecated PdfDocument.render() API and replaced with linear rendering. See below for more info.
• setup: Fixed blunder in headers cache logic that would cause existing headers to be always reused regardless of version. Note, this did not affect release workflows, only local source re-installs.
• Show path of linked binary in pypdfium2 -v.
• conda: Improved installation docs and channel config.
• conda/workflows: Added ability to (re-)build pypdfium2_raw bindings with any given version of pdfium. Fixes {issue}279.
• Made reference bindings more universal by including V8, XFA and Skia symbols. This is possible due to the dynamic symbol guards.
• Instruct ctypesgen to exclude some unused alias symbols pulled in from struct tags.
• Improved issue templates, added pull request template.
• Improved ctypesgen (pypdfium2-team fork).

Rationale for PdfDocument.render() deprecation

• The parallel rendering API unfortunately was an inherent design mistake: Multiprocessing is not meant to transfer large amounts of pixel data from workers to the main process.
• This was such a heavy drawback that it basically outweighed the parallelization, so there was no real performance advantage, only higher memory load.
• As a related problem, the worker pool produces bitmaps at an indepedent speed, regardless of where the receiving iteration might be, so bitmaps could queue up in memory, possibly causing an enormeous rise in memory consumption over time. This effect was pronounced e.g. with PNG saving via PIL, as exhibited in Facebook's nougat project.
• Instead, each bitmap should be processed (e.g. saved) in the job which created it. Only a minimal, final result should be sent back to the main process (e.g. a file path).
• This means we cannot reasonably provide a generic parallel renderer, instead it needs to be implemented by callers.
• Historically, note that there had been even more faults in the implementation:
  • Prior to 4.22.0, the pool was always initialized with os.cpu_count() processes by default, even when rendering less pages.
  • Prior to 4.20.0, a full-scale input transfer was conducted on each job (rendering it unusable with bytes input). However, this can and should be done only once on process creation.
• pypdfium2's rendering CLI cleanly re-implements parallel rendering to files. We may want to turn this into an API in the future.

Due to the potential for serious issues as outlined above, we strongly recommend that end users update and dependants bump their minimum requirement to this version. Callers should move away from PdfDocument.render() and use PdfPage.render() instead.

4.22.0

Changes (Release 4.22.0)

Summary (pypdfium2)

• Changed PDFIUM_PLATFORM=none to strictly exclude all data files. Added new target system consuming bindings and version files supplied by the caller. Again, the setup API implications were accepted. Packagers that used none to bind to system pdfium will have to update.
• Enhanced integration of separate modules. This blazes the trail for conda packaging. We had to move metadata back to setup.cfg since we need a dynamic project name, which pyproject.toml does not support.
• Major improvements to version integration.
  • Ship version info as JSON files, separately for each submodule. Expose as immutable classes. Legacy members have been retained for backwards compatibility.
  • Autorelease uses dedicated JSON files for state tracking and control.
  • Read version info from git describe, providing definite identification.
  • If a local git repo is not available or git describe failed (e.g. sdist or shallow checkout), fall back to a supplied version file or the autorelease record. However, you are strongly encouraged to provide a setup that works with git describe where possible.
• Added musllinux aarch64 wheel. Thanks to @jerbob92.
