* Improve readability of code that uses the Qt signed size typev5.10.0-rc2Simon Hausmann2017-11-281-1/+1
| | | | | | | | | | | | | | | | | During the container BoF session at the Qt Contributor Summit 2017 the name of the signed size type became a subject of discussion in the context of readability of code using this type and the intention of using it for all length, size and count properties throughout the entire framework in future versions of Qt. This change proposes qsizetype as new name for qssize_t to emphasize the readability of code over POSIX compatibility, the former being potentially more relevant than the latter to the majority of users of Qt.

* Fix handling of mirroring upscaling in simple bilinear upscalerAllan Sandfeld Jensen2017-08-101-7/+10
| | | | | | | | | | Calculates the correct offsets and coordinate transforms for the intermediate buffer. This means we can conceptually simplify our path switches instead of having downscale routines handling mirrored upscaling.

* Allow QImage with more than 2GByte of image dataAllan Sandfeld Jensen2017-07-081-1/+1
| | | | | | | | | | | | Changes internal data-size and pointer calculations to qssize_t. Adds new sizeInBytes() accessor to read byte size, and marks the old one deprecated.

* Manually vectorize ARGB32toARGB32PM for SSE4.1 and NEONAllan Sandfeld Jensen2017-01-311-13/+0
| | | | | | | | | | | | Manually vectorizing is significantly faster because we can optimize for common cases like long stretches of opaque or transparent pixels. This is both smaller and faster than the auto-vectorized version, it is also much faster than the autovectorized version for AVX2 which then can be removed.

* Fix blending of RGB32 on RGB32 with partial opacityAllan Sandfeld Jensen2016-12-031-5/+3
| | | | | | | | | | | | | The alpha channel of an RGB32 image was not properly ignored when doing blending with partial opacity. Now the alpha value is properly ignored, which is both more correct and faster. This also makes SSE2 and AVX2 implementations match NEON which was already doing the right thing (though had dead code for doing it wrong).

* Avoid auto-vectorization of epilogues of manual vectorizationAllan Sandfeld Jensen2016-10-111-4/+4
| | | | | | | | | | Defines a structure that tells the compiler in no uncertain terms the maximum number of times a loop can be run.

* Add AVX2 autovectorized versions of premultiplyAllan Sandfeld Jensen2015-03-101-0/+54
Following up on using GCC's autovectorizing for faster SSE4.1 premultiply, this patch adds specialized autovectorized versions of premultiply for AVX2, giving another almost doubling in speed. To make the speed up for AVX2 and also SSE4_1 available to non-GCC compilers, the target-specific methods have been moved to separate files.
