* Fixed potential access violation in QPixmap::copy() for <32 bit pixmaps.Samuel Rødal2013-04-221-2/+3
| | | | | | | | | | | | | QImage is supposed to maintain the invariant that each scan-line begins on a 4-byte boundary, so we need to verify that this is the case before using the optimized path of short-cutting QImage::copy() by referencing the source image's bits directly.

| * Prevent always deep-copying in QPixmap::toImage() for raster pixmaps.Samuel Rødal2010-12-071-5/+8
| | | | | | | | | | | | | | | | | | Calling paintEngine() can cause a deep copy since it will indirectly call the bits() function. Since we don't want to create a paint engine if it doesn't exist we should access the QImageData paintEngine variable directly instead. Reviewed-by: Olivier Goffart

* Start the implementation of in-place recoding for imagesBenjamin Poulain2010-06-201-95/+119
| | | | | | | | | | | | | | | | | | | | | Currently, with the graphics system raster, converting from images to QPixmap often needs to allocate a new image to convert the right format. For example, for an image in ARGB32 of 10 mbytes, we need to allocate a second image of 10 mbytes in ARGB32_PM to convert the source image in the right format for pixmap. This can create a hight peak of memory, and is a bit slower than it should. This patch introduce in-place conversion of images when they are loaded with QPixmap::loadFromData(). The images are loaded in their default format by QImageReader, and are then converted in-place, trying to reduce memory allocations. Reviewed-by: Samuel Rødal

* | Speed up QPixmap::width(), height(), isNull() and depth().Andreas Aardal Hanssen2009-06-171-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves the w, h, d variables to QPixmapData and introduces is_null to keep track of nullness. This is possible only because QPixmapData is internal API; otherwise we'd have to be smarter. The optimization makes the QPixmap::width() function take 7 instructions, down from 34 before. For the calculator demo in the declarative ui branch this reduces a block of 750000 instructions (out of 30000000) to around 100000-150000 instructions. Tested on Windows, Linux, Mac.
