- CUPS Filters Summary (Till)
- Current releases are v1.25.0 on 6 June 2019 and v1.25.1 on 5 July 2019
- CUPS Filters v1.25.1 is a bug fix release for the filters, mainly for the new
pdftoraster filter.
- CUPS Filters v1.25.0 changes the pdftoraster filter to only use stable/documented
APIs of Poppler (Tanmay Anand's Google Summer of Code 2019 project) and the deprecated,
Poppler-based filters pdftoijs and pdftoopvp are finally completely removed. Now
Poppler is only used for the pdftoraster filter. Poppler's unstable/internal APIs are
nowhere used any more in cups-filters.
Note for distribution packagers: cups-filters now uses libpoppler-cpp for pdftoraster.
- CUPS Filters v1.25.1 on 5 July 2019 (Till)
- imagetopdf: Fixed crash when no PPD file was supplied (Pull request #133).
- pdftoraster: Fixed offset issues leading to segmentation faults (Issue #131, Pull
request #132).
- pdftoraster: Added anti-aliasing for better raster image quality (Pull request #129).
- pdftoraster: Added graceful handling of zero-page input (Issue #117, Pull request #127).
- CUPS Filters v1.25.0 on 6 June 2019 (Till)
- pdftoijs, pdftoopvp: Removed these deprecated filters completely as there is no demand
for them any more. They also used unstable, undocumented APIs of Poppler.
- pdftoraster: Changed from using unstable, undocumented APIs of Poppler to stable,
documented ones, to improve maintainability of this filter, and with it of the
cups-filters package. Thanks to Tanmay Anand for contributing this as his Google
Summer of Code 2019 project.
- libcupsfilters: Added support for color spaces CMY and RGBW when using filters without
PPD file (mainly for development and debugging, option "print-color-mode" with values
"cmy-XX" and "rgbw-XX" with XX being the number of bits per color).
- Progress on 2018 unfinished projects
