* Add color space model, making gray color spaces explicitAllan Sandfeld Jensen2024-04-051-3/+8

* GUI: add CMYK painting supportGiuseppe D'Angelo2024-04-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a CMYK 8bpp format to QImage. The idea is to enable the transport of CMYK images inside Qt, for instance to be loaded/saved from files or painted on CMYK capable paint devices (e.g. PDF). Also, rasterization support *from* a CMYK image is added (on top of a RGB surface), as well as CMYK image scaling/conversion. Conversion and rasterization between CMYK and RGB isn't particularly optimized nor it honors any colorspaces yet. The overall idea is to match 1:1 the existing behavior of CMYK QColor (which get naively changed to RGB; there isn't colorspace support in QPainter yet). There are no plans to add rasterization *towards* CMYK. Image save/load in native CMYK formats will be added in future commits. This work has been kindly sponsored by the QGIS project (https://qgis.org/). [ChangeLog][QtGui] Support for 8-bit CMYK images has been added.

* Replace qExchange calls with std::exchangeFabian Kosmale2022-09-281-1/+1
| | | | | | | | | | | | | | | | | | | | | qExchange is one of the few remaining functionalities that have not been moved out of qglobal. Given that std::exchange exists in the standard, we can simply move to it everywhere... ...if it weren't for the fact that std::exchange is only constexpr in C++20, and only has its noexceptness specified in (most likely) C++23. Still, we want to move to the existing std functionality where possible, to allow the removal of qglobal includes in lieu of something more fine-grained in the future. So leave any constexpr calls[1] alone for now (and observe that none of our current usages cares about the conditional noexceptness), but replace everything else.

| | | | | | | | | | | | | | | | | | Instead of using the overly-generic qSwap() monster, use - qt_ptr_swap() for swapping raw pointers - member-swap for swapping smart pointers - std::swap() for swapping scalars In QtCore, this has proven to give a nice reduction in compile time for Qt users, cf. b1b0c2970e480ef460a61f37fa430dc443390358.

* Centralize the implementation of move assignment operatorsGiuseppe D'Angelo2020-10-031-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we have two main strategies for dealing with move assignment in Qt: 1) move-and-swap, used by "containers" (in the broad sense): containers, but also smart pointers and similar classes that can hold user-defined types; 2) pure swap, used by containers that hold only memory (e.g. QString, QByteArray, ...) as well as most implicitly shared datatypes. Given the fact that a move assignment operator's code is just boilerplate (whether it's move-and-swap or pure swap), provide two _strictly internal_ macros to help write them, and apply the macros across corelib and gui, porting away from the hand-rolled implementations. The rule of thumb when porting to the new macros is: * Try to stick to the existing code behavior, unless broken * if changing, then follow this checklist: * if the class does not have a move constructor => pure swap (but consider ADDING a move constructor, if possible!) * if the class does have a move constructor, try to follow the criteria above, namely: * if the class holds only memory, pure swap; * if the class may hold anything else but memory (file handles, etc.), then move and swap. Noteworthy details: * some operators planned to be removed in Qt 6 were not ported; * as drive-by, some move constructors were simplified to be using qExchange(); others were outright broken and got fixed; * some contained some more interesting code and were not touched.
