| | * QGradientCache: fix a new/delete mismatchMarc Mutz2017-01-141-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The printf-style version of QDebug expands to a lot less code than the std::ostream-style version. Of course, you pay in type safety (but compilers warn about it these days), you cannot stream complex Qt types and streaming QStrings is awkward, but in many cases you actually improve on readability. But the main reason is that something that's not supposed to be executed under normal operation has no business bloating executable code size. This is not an attempt at converting all qWarnings() to printf-style, only the low-hanging fruit. In this first part, replace qWarning() << "..."; with qWarning("..."); In QTransform shared warning strings. Saves 3KiB in text size on optimized GCC 5.3 AMD64 builds.

* | QImage support for RGB30 formatsAllan Sandfeld Jensen2014-07-041-0/+6
|/ | | | | | | | | | | | | | 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.

* Fix fast painting of clipped text on non RGB32 formatsAllan Sandfeld Jensen2014-05-281-4/+3
| | | | | | | | | | QRasterPaintEngine::alphaPenBlt makes the assumption that a device with bit depth 32 has optimized alphamapBlit and alphaRGBBlit routines. This will fail on RGBA8888 format resulting in some text not being rendered. Change-Id: Ia7d88bb0e3094894affceda1acc42396b67b3677 Reviewed-by: Gunnar Sletta <gunnar.sletta@jollamobile.com>

* 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.

* Unify glyph format between QFontEngine and QFontEngineGlyphCacheTor Arne Vestbø2014-02-191-10/+10
| | | | | | | | | | | | Instead of the glyph cache having its own cache type that always mapped one to one to a font engine glyph format, causing confusion and needless conversions, the glyph caches now use QFontEngine's glyph format enum. This also removes the iffy use of an int for the glyphFormat in the font engines. Change-Id: I529bad5c179e004f63e152f7dcc311d298c3db98 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
* Export optimized premultiply and unpremultiply methodsAllan Sandfeld Jensen2014-02-101-19/+19
| | | | | | | | | | | | | | | | 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.
