| | | | | | | | | | With the introduction of CMYK32 the old logic of assuming depth meant compatible alpha version no longer works.

* GUI: add CMYK painting supportGiuseppe D'Angelo2024-04-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | These APIs started out as private APIs in qnumeric_p.h, but have since been made pseudo-public in qnumeric.h. The qnumeric_p.h versions just forward to the qnumeric.h ones, so just use the latter. This is in preparation of removing the {add,sub,mul}_overflow versions, which, despite being defined in the unnamed namespace, don't sport the q prefix, so potentially clash with global symbols. The change is a simple textual search and replace, manually excluding qnumeric_p.h. Picking to 6.5 to avoid cherry-pick conflicts going forward.
