| | * QGradientCache: fix a new/delete mismatchMarc Mutz2017-01-141-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f839f536 fixed a data race in the gradient cache by reference-counting the CacheInfo objects stored in the cache. 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.

| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Remove workarounds for RVCT compiler bugsThiago Macieira2015-01-061-28/+1
| | | | | | | | | | | | | | | This does not try to remove support for RVCT. There has been no report of it working or failing to work, so the status continues to be unknown. In particular, the inline assembly code in atomic_armv[56].h remains in place. This commit only removes workarounds for compiler bugs or bogus warnings, assuming that anyone using this compiler has updated since Qt last tried to use it for Symbian in 2011. Note also how anonymous unions are now part of the language in C++11. Change-Id: Idc4fab092beb31239eb08b7e139bce2602adae81 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* QImage support for RGB30 formatsAllan Sandfeld Jensen2014-07-041-9/+108
| | | | | | | | | | | | | | Adds basic support for 10-bit per color channel formats to QImage and the XCB plugin. This will make it possible to paint to and from these formats, but only at 8-bit per color channel accuracy. This also fixes Qt5 applications on X11 with native 30bit depth. [ChangeLog][QtGui][QImage] Added support for 10-bit per color channel image formats.

* Avoid out of bounds memory reads when scaling imagesLars Knoll2014-03-281-1/+1
| | | | | | | | | | | | | | | | The calculation of the width/height required for the scaling algorithm was prone to floating point rounding issues, where the lower value got rounded down, the higher one rounded up. This could lead to a situation where we iterated over one more line/pixel in the line than we have in the source image. Correct this by passing the dimension of the source image into the function and bounds checking the values before iterating.

* Export optimized premultiply and unpremultiply methodsAllan Sandfeld Jensen2014-02-101-31/+4
| | | | | | | | | | | | | | | | This patch optimizes the unpremultiply method further by using a lookup table to avoid any divisions at all. The opportunity is taken to export both premultiply and unpremultiply since they are commonly used methods relevant to the exported QRgb type that can be both premultiplied and unpremultipled ARGB. [ChangeLog][QtGui][QColor] Exported highly optimized methods for premultiply and unpremultiply of QRgb values.

* Round evenly in INV_PREMULAllan Sandfeld Jensen2014-01-291-1/+2
| | | | | | | | | | | | | | Currently INV_PREMUL rounds strictly down. While PREMUL rounds evenly. This patch adds 0x8000 to the intermediate results in INV_PREMUL before right shifting, thereby achieving even rounding. The rounding also makes PREMUL(INV_PREMUL()) into an identify operation, which means we can safely convert ARGB32PM to ARGB32 and back without ever losing color details. A test is added to verify this. Change-Id: I1267e109caddcff0c01d726cb5c1c1e9fa5f7996 Reviewed-by: Gunnar Sletta <gunnar.sletta@jollamobile.com>
* Make conversion of semi-transparency to opaque formats consistentAllan Sandfeld Jensen2014-01-201-0/+1
| | | | | | | | | | | | | | Currently the non-standard opaque formats all perform inverse premultiply on semi transparent pixels when saving. This is only performed on RGB16 and RGB32 when explicitly converting to the formats, but not when drawing. This patch changes the conversion to be consistent across the board so less common formats are treated the same as the most common ones. This also makes drawing and converting to the these formats much faster.

* Optimize INV_PREMULAllan Sandfeld Jensen2014-01-161-6/+10
| | | | | | | | | | | | | | | | Our inverse premultiply is rather unoptimized. It's major weakness is using three divide operation which are the slowest integer operations. This patch reduces the three divisions to just one but using an approximation that is accurate for all uchar values. The patch also adds a general short-cut for alpha==255. Together these improvements makes it 2 to 16 times faster depending on how many 0 and 255 alpha values are encountered.
