------------------------------------------------------------------- Sun Apr 14 09:42:17 UTC 2024 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 16.1.2 Remove 0001-Drop-shebang-from-non-executable-files.patch from build v16.1.2 Fixed test suite failure when using Ghostscript 10.3. Other minor corrections. v16.1.1 Fixed PyPy 3.10 support. v16.1.0 Improved hOCR renderer is now default for left to right languages. Improved handling of rotated pages. Previously, OCR text might be missing for pages that were rotated with a /Rotate tag on the page entry. Improved handling of cropped pages. Previously, in some cases a page with a crop box would not have its OCR applied correctly and misalignment between OCR text and visible text coudl occur. Documentation improvements, especially installation instructions for less common platforms. v16.0.4 Fixed some issues for left-to-right text with the new hOCR renderer. It is still not default yet but will be made so soon. Right-to-left text is still in progress. Added an error to prevent use of several versions of Ghostscript that seem corrupt existing text in input PDFs. Newly generated OCR is not affected. For best results, use Ghostscript 10.02.1 or newer, which contains the fix for the issue. v16.0.3 Changed minimum required Ghostscript to 9.54, to support users of RHEL 9 and its derivatives, since that is the latest version available there. Removed warning message about CVE-2023-43115, on the assumption that most distributions have backported the patch by now. v16.0.2 Temporarily changed PDF text renderer back to sandwich by default to address regressions in macOS Preview. v16.0.1 Fixed text rendering issue with new hOCR text renderer - extraneous byte order marks. Tightened dependencies. v16.0.0 Added OCR text renderer, combined the best ideas of Tesseract's PDF generator and the older hOCR transformer renderer. The result is a hopefully permanent fix for wordssmushedtogetherwithoutspaces issues in extracted text, better registration/position of text on skewed baselines :issue:`1009`, fixes to character output when the German Fraktur script is used :issue:`1191`, proper rendering of right to left languages (Arabic, Hebrew, Persian) :issue:`1157`. Asian languages may still have excessive word breaks compared to expectations. The new renderer is the default; the old sandwich renderer is still available using ``--pdf-renderer sandwich``; the old hOCR renderer is no more. The ``ocrmypdf.hocrtransform`` API has changed substantially. Support for Python 3.9 has been dropped. Python 3.10+ is now required. pikepdf >= 8.8.0 is now required. v15.4.4 Fixed documentation for installing Ghostscript on Windows. :issue:`1198` Added warning message about security issue in older versions of Ghostscript. v15.4.3 Fixed deprecation warning in pikepdf older than 8.7.1; pikepdf >= 8.7.1 is now required. v15.4.2 We now raise an exception on a certain class of PDFs that likely need an explicit color conversion strategy selected to display correctly for PDF/A conversion. Fixed an error that occurred while trying to write a log message after the debug log handler was removed. v15.4.1 Fixed misc/watcher.py regressions: accept ``--ocr-json-settings`` as either filename or JSON string, as previously; and argument count mismatch. :issue:`1183,1185` We no longer attempt to set /ProcSet in the PDF output, since this is an obsolete PDF feature. Documentation improvements. v15.4.0 Added new experimental APIs to support offline editing of the final text. Specifically, one can now generate hOCR files with OCRmyPDF, edit them with some other tool, and then finalize the PDF. They are experimental and subject to change, including details of how the working folder is used. There is no command line interface. Code reorganization: executors, progress bars, initialization and setup. Fixed test coverage in cases where the coverage tool did not properly trace into threads or subprocesses. This code was still being tested but appeared as not covered. In the test suite, reduced use of subprocesses and other techniques that interfere with coverage measurement. Improved error check for when we appear to be running inside a snap container and files are not available. Plugin specification now properly defines progress bars as a protocol rather than defining them as "tqdm-like". We now default to using "forkserver" process creation on POSIX platforms rather than fork, since this is method is more robust and avoids some issues when threads are present. Fixed an instance where the user's request to ``--no-use-threads`` was ignored. If a PDF does not have language metadata on its top level object, we add the OCR language. Replace some cryptic test error messages with more helpful ones. Debug messages for how OCRmyPDF picks the colorspace for a page are now more descriptive. v15.3.1 Fixed an issue with logging settings for misc/watcher.py introduced in the previous release. :issue:`1180` We now attempt to preserve the input's extended attributes when creating the output file. For some reason, the macOS build now needs OpenSSL explicitly installed. Updated documentation on Docker performance concerns. v15.3.0 Update misc/watcher.py to improve command line interface using Typer, and support ``.env`` specification of environment variables. Improved error messages. Thanks to @mflagg2814 for the PR that prompted this improvement. Improved error message when a file cannot be read because we are running in a snap container. v15.2.0 Added a Docker image based on Alpine Linux. This image is smaller than the Ubuntu-based image and may be useful in some situations. Currently hosted at jbarlow83/ocrmypdf-alpine. Currently not available in ARM flavor. The Ubuntu Docker is now aliased to jbarlow83/ocrmypdf-ubuntu. Updated Docker documentation. v15.1.0 We now require Pillow 10.0.1, due a serious security vulnerability in all earlier versions of that dependency. The vulnerability concerns WebP images and could be triggered in OCRmyPDF when creating a PDF from a malicious WebP image. Added some keyword arguments to ``ocrmypdf.ocr`` that were previously accepted but undocumented. Documentation updates and typing improvements. ------------------------------------------------------------------- Fri Sep 29 20:02:25 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 15.0.2 Added Python 3.12 to test matrix. Updated documentation for notes on Python 3.12, 32-bit support and some new features in v15. ------------------------------------------------------------------- Wed Sep 27 17:39:10 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 15.0.1 v15.0.1 Wheels Python tag changed to py39. Marked as a expected fail a test that fails on recent Ghostscript versions. Clarified documentation and release notes around the extent of 32-bit support. Updated installation documentation to changes in v15. v15.0.0 Dropped support for Python 3.8. Dropped support many older dependencies - see pyproject.toml for details. Generally speaking, Ubuntu 22.04 is our baseline system. Dropped support for 32-bit Linux wheels. You must use a 64-bit operating system, and 64-bit versions of Python, Tesseract and Ghostscript to use OCRmyPDF. Many of our dependencies are dropping 32-bit builds (e.g. Pillow), and we are following suit. (Maintainers may still build 32-bit versions from source.) Changed to trusted release for PyPI publishing. pikepdf memory mapping is enabled again for improved performance, now an issue with pikepdf has been fixed. ocrmypdf.helpers.calculate_downsample previously had two variants, one that took a PIL.Image and one that took a tuple[int, int]. The latter was removed. The snap version of ocrmypdf is now based on Ubuntu core22. We now account situations where a small portion of an image on a page reports a high DPI (resolution). Previously, the entire page would be rasterized at the highest resolution, which caused performance problems. Now, the page is rasterized at a resolution based on the average DPI of the page, weighted by the area that each feature occupies. Typically, small areas of high resolution in PDFs are errors or quirks from the repeated use of assets and high resolution is not beneficial. :issue:`1010,1104,1004,1079,1010` Ghostscript color conversion strategy is now configurable. :issue:`1143` 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. ------------------------------------------------------------------- Fri Jun 23 17:12:46 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 14.3.0 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. Fixed :issue:`977`, where images inside Form XObjects were always excluded from image optimization. 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. ------------------------------------------------------------------- Thu Apr 20 14:38:18 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 14.1.0 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. ------------------------------------------------------------------- Thu Apr 13 18:43:12 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 14.0.4 ------------------------------------------------------------------- Tue Feb 14 18:30:21 UTC 2023 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 14.0.2 ------------------------------------------------------------------- Tue May 24 09:28:03 UTC 2022 - Frank Kunz <mailinglists@kunz-im-inter.net> - Update to version 13.4.4 ------------------------------------------------------------------- Wed Jul 29 04:38:12 UTC 2020 - Karl Cheng <qantas94heavy@gmail.com> - Update to version 10.3.1 ------------------------------------------------------------------- Tue Dec 5 13:59:32 UTC 2017 - t.gruner@katodev.de - update to version 4.5.6 ------------------------------------------------------------------- Wed Mar 30 12:07:20 UTC 2016 - t.gruner@katodev.de - update to version 4.0.7 ------------------------------------------------------------------- Wed Jan 20 14:20:13 UTC 2016 - t.gruner@katodev.de - update to version 3.1.1 ------------------------------------------------------------------- Wed Feb 4 13:34:07 UTC 2015 - t.gruner@katodev.de - update to version 2.2 ------------------------------------------------------------------- Sun Oct 12 21:08:30 UTC 2014 - t.gruner@katodev.de - Add a view patches from Christoph ------------------------------------------------------------------- Mon Sep 22 20:52:14 UTC 2014 - t.gruner@katodev.de - update to version 2.1 ------------------------------------------------------------------- Sun Dec 29 19:30:00 UTC 2013 - soeren@ploennigs.net - initial build - added patch to use system dirs (/tmp, /usr/share/OCRmyPDF) - moved jhove to separate package
