* Implement support for 16bpc image formatsAllan Sandfeld Jensen2018-08-111-4/+15
| | | | | | | | | | | | | | Adds support for 16bit per color image formats in QImage. This makes it possible to read and write 16bpc PNGs, and take full advantage of the 16bpc paint engine. [ChangeLog][QtGui][QImage] QImage now supports 64bit image formats with 16 bits per color channel, compatible with 16bpc PNG or RGBA16 OpenGL formats.

|/ | | | | | | | | | | | | | The simple scaling that only samples every input pixel once, can be used with downscaling < 2x as well if we just handle the case where the input can't be in the intermediate buffer. At the same time the handling of the intermediate buffer has been moved out of simple scale helper functions so the code can be shared and the AVX2 optimizations also used for non-argb32pm formats.

| * Improve readability of code that uses the Qt signed size typev5.10.0-rc2Simon Hausmann2017-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * QGradientCache: fix a new/delete mismatchMarc Mutz2017-01-141-1/+7

To this end, QSpanData gained a ref-counted pointer to the CacheInfo whose members it references to keep the object alive for as long as the QSpanData object needs it. However, since CacheInfo is only later defined in qpaintengine_raster.cpp, the counted pointer's payload was chosen as CacheInfo's base class, QSharedData. As it turns out, e.g. in the QPainter test, the data race was real and so QSpanData ends up being the entity that destroys (at least some) CacheInfos, either in its destructor, or in the setup() method. Since QSharedData's destructor is not virtual, and QExplicitlySharedDataPointer<QSharedData> knows nothing of the CacheInfo-ness of its payload, we end up calling the destructor of the base class, and not the CacheInfo one. Fix by using QSharedPointer instead, which stores the correct deleter internally. Ideally, QSpanData would contain a QSharedPointer<const void>, but QSharedPointer's implementation is deficient in that respect and does not compile when instantiated with void, and we can't use std::shared_ptr, yet, so introduce an arbitrary base class, Pinnable, to be used instead.

* | NEON optimized bilinear samplingAllan Sandfeld Jensen2015-12-171-23/+72
|/ | | | | | | | | | | | | | | Adds NEON version of interpolate_4_pixels used by smooth upscaling, and bilinear sampling. The SSE2 version is reordered to match the NEON version so they have the same order of operations and a faster version that loads directly into vector registers. Testing is extended so we have a test of smoothness that can catch more possible mistakes.

* Initialize function tables without QGuiApplicationAllan Sandfeld Jensen2015-12-071-2/+0
| | | | | | | | | | | | | QImage can be used without QGuiApplication, but wihout QGuiApplication the accelerated methods would not be used. This patch changes the initialization of the QtGui function tables to happen in static object constructors on QtGui load, instead of in the QGuiApplication init.

* Fix repremultiply from RGB64 to RGB30Allan Sandfeld Jensen2015-08-111-12/+14
| | | | | | | | | | | | | | Just like from RGB32 to RGB30 we must also repremultiply when converting from RGB64 because the alpha channel loses more precision than the other color channels. Since this is not approximated accurately in the simple blending functions and the functions are no longer needed now the main render engine supports higher accuracy, the simple blending routines for RGB30 have been removed.

| | | | | | | | | | | | | | | | | | When a premultiplied alpha changes value because it is rounded to fewer bits the premultiplied colors may need to be recalculated with the new value. Otherwise the color will both be wrong and potentially invalid. Change-Id: I9ec74a22aac73cd7ffab04e180cf2bf35bb4c315 Reviewed-by: Gunnar Sletta <gunnar@sletta.org>
