* Port QImage::Format_CMYK32 to CMYK8888Giuseppe D'Angelo2024-04-041-2/+2
| | | | | | | | | | | | Follow the established convention that byte-oriented image formats have the "8888" suffix, not "32". The old enum name is temporarily left to help port other submodules. This work has been kindly sponsored by the QGIS project (https://qgis.org/). Change-Id: I4b6f10cb22312b614cb9cf4b0ac439907276c538 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>
* Add support for CMYK file I/O in JPEGGiuseppe D'Angelo2024-04-031-20/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JPEG part 6 defines CMYK support. This commit adds such support to the JPEG plugin. A *very* interesting discovery is the fact that Photoshop inverts the meaning of the CMYK color channels when saving into JPEG: 0 means "full ink", and 255 means "no ink". Most other image viewers/editors follow the same interpretation, I imagine for compatibility. But others, like Adobe Reader, don't (???) -- a PDF expects a DCT encoding with 0 meaning "no ink". I am adding a SubType to the image I/O handler to let the user choose what they want, defaulting to Photoshop behavior. Also, turns out that Qt was already loading CMYK files and converting them to RGB. I don't think we should do automatic, lossy conversions (we were not taking into account an eventual colorspace...), so I'm changing that loading to yield a CMYK QImage. Finally: save the colorspace, even if it's a CMYK image. QColorSpace doesn't support anything but RGB matrix-based colorspaces. Yet, it can load an arbitrary ICC profile, and will store it even if it's unable to use it. We can use this fact to preserve the colorspace embedded in CMYK images, or let users set an arbitrary ICC profile on them through Qt APIs, and then saving the result in JPEG. [ChangeLog][QtGui][JPEG] Added support for loading and saving of JPEG files in 8-bit CMYK format. When loading a CMYK JPEG file, Qt used to convert it automatically to a RGB image; now instead it's kept as-is. This work has been kindly sponsored by the QGIS project (https://qgis.org/).

* Mark all of Qt as free of Q_FOREACH, except where it isn'tMarc Mutz2023-08-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | The density of Q_FOREACH uses in this and some other modules is still extremely high, too high for anyone to tackle in a short amount of time. Even if they're not concentrated in just a few TUs, we need to make progress on a global QT_NO_FOREACH default, so grab the nettle and stick to our strategy: Mark the whole of Qt with QT_NO_FOREACH, to prevent new uses from creeping in, and whitelist the affected TUs by #undef'ing QT_NO_FOREACH locally, at the top of each file. For TUs that are part of a larger executable, this requires these files to be compiled separately, so add them to NO_PCH_SOURCES (which implies NO_UNITY_BUILD_SOURCES, too). In tst_qglobal.cpp and tst_qcollections.cpp change the comment on the #undef QT_NO_FOREACH to indicate that these actually test the macro.

* Fix setScaledClipRect autotest for reading SVG formatEirik Aavitsland2022-09-271-2/+5
| | | | | | | | | | | | | | | | | | | | | | | Since setScaledClipRect will actually render only the necessary parts, there may be insignificant differences in rounding/anitaliasing compared to rendering the whole image first and then clipping. Hence this autotest case would always fail. But that would not happen in CI, since it tests qtbase without the qtsvg module, and then the SVG tests are skipped. (For some reason, one ran into this in wayland testing and made an exception for that, but obviously this failure has nothing to do with wayland). Work around the issue by converting the rendered images to 4 bpc format, so the differences in the least significant bits get truncated away.
