# v14
|
|
|
|
## v14.4.0
|
|
|
|
- Digitally signed PDFs are now detected. If the PDF is signed, OCRmyPDF will
|
|
refuse to modify it. Previously, only encrypted PDFs were detected, not
|
|
those that were signed but not encrypted. {issue}`1040`
|
|
- In addition, `--invalidate-digital-signatures` can be used to override the
|
|
above behavior and modify the PDF anyway. {issue}`1040`
|
|
- tqdm progress bars replaced with "rich" progress bars. The rich library is
|
|
a new dependency. Certain APIs that used tqdm are now deprecated and will
|
|
be removed in the next major release.
|
|
- Improved integration with GitHub Releases. Thanks to @stumpylog.
|
|
|
|
## v14.3.0
|
|
|
|
- Renamed master branch to main.
|
|
- Improve PDF rasterization accuracy by using the `-dPDFSTOPONERROR` option
|
|
to Ghostscript. Use `--continue-on-soft-render-error` if you want to render
|
|
the PDF anyway. The plugin specification was adjusted to support this feature;
|
|
plugin authors may want to adapt PDF rasterizing and rendering
|
|
plugins. {issue}`1083`
|
|
- The calculated deskew angle is now recorded in the logged output. {issue}`1101`
|
|
- Metadata can now be unset by setting a metadata type such as `--title` to an
|
|
empty string. {issue}`1117,1059`
|
|
- Fixed random order of languages due to use of a set. This may have caused output
|
|
to vary when multiple languages were set for OCR. {issue}`1113`
|
|
- Clarified the optimization ratio reported in the log output.
|
|
- Documentation improvements.
|
|
|
|
## v14.2.1
|
|
|
|
- Fixed {issue}`977`, where images inside Form XObjects were always excluded
|
|
from image optimization.
|
|
|
|
## v14.2.0
|
|
|
|
- Added `--tesseract-downsample-above` to downsample larger images even when
|
|
they do not exceed Tesseract's internal limits. This can be used to speed
|
|
up OCR, possibly sacrificing accuracy.
|
|
- Fixed resampling AttributeError on older Pillow. {issue}`1096`
|
|
- Removed an error about using Ghostscript on PDFs with that have the /UserUnit
|
|
feature in use. Previously, Ghostscript would fail to process these PDFs,
|
|
but in all supported versions it is now supported, so the error is no longer
|
|
needed.
|
|
- Improved documentation around installing other language packs for Tesseract.
|
|
|
|
## v14.1.0
|
|
|
|
- Added `--tesseract-non-ocr-timeout`. This allows using Tesseract's deskew
|
|
and other non-OCR features while disabling OCR using `--tesseract-timeout 0`.
|
|
- Added `--tesseract-downsample-large-images`. This downsamples larges images
|
|
that exceed the maximum image size Tesseract can handle. Large images may still
|
|
take a long time to process, but this allows them to be processed if that
|
|
is desired.
|
|
- Fixed {issue}`1082`, an issue with snap packaged building.
|
|
- Change linter to ruff, fix lint errors, update documentation.
|
|
|
|
## v14.0.4
|
|
|
|
- Fixed {issue}`1066, 1075`, an exception when processing certain malformed PDFs.
|
|
|
|
## v14.0.3
|
|
|
|
- Fixed {issue}`1068`, avoid deleting /dev/null when running as root.
|
|
- Other documentation fixes.
|
|
|
|
## v14.0.2
|
|
|
|
- Fixed {issue}`1052`, an exception on attempting to process certain nonconforming PDFs.
|
|
- Explicitly documented that Windows 32-bit is no longer supported.
|
|
- Fixed source installation instructions.
|
|
- Other documentation fixes.
|
|
|
|
## v14.0.1
|
|
|
|
- Fixed some version checks done with smart version comparison.
|
|
- Added missing jbig2dec to Docker image.
|
|
|
|
## v14.0.0
|
|
|
|
- Dropped support for Python 3.7.
|
|
- Dropped support generally speaking, all dependencies older than what Ubuntu 20.04
|
|
provides.
|
|
- Ghostscript 9.50 or newer is now required. Shims to support old versions were
|
|
removed.
|
|
- Tesseract 4.1.1 or newer is now required. Shims to support old versions were
|
|
removed.
|
|
- Docker image now uses Tesseract 5.
|
|
- Dropped setup.cfg configuration for pyproject.toml.
|
|
- Removed deprecation exception PdfMergeFailedError.
|
|
- A few more public domain test files were removed or replaced. We are aiming for
|
|
100% compliance with SPDX and generally towards simplifying copyright.
