* Fixes the documentation of QGraphicsEffect::update().Yoann Lopes2010-06-301-6/+3
| | | | | | | Reflects now the real behavior of this function. Related to a false bug report (QT-3481). Reviewed-by: sroedal
* Fixed scrolling bugs in widget graphics effect backend.Samuel Rødal2010-05-071-1/+1
| | | | | | | | | | | The cache wasn't invalidated for widgets with a graphics effect inside a scrolling QScrollArea, so for now we disable caching for widget source pixmaps. Also, we can't clip the source pixmap to device coordinates since there's no knowledge of which areas of the source pixmap the effect uses to compute the visible pixels. See change fd30cc9fabe6fc023 for the graphics item effect backend fix. Reviewed-by: Bjørn Erik Nilsen
* Documented behavior of blur effect radius and drop shadow offset.Samuel Rødal2010-02-181-2/+10
| | | | | | | | Our graphics effects are always done in device coordinates (unless they can be done in logical coordinates with the same result as an optimization, e.g. opacity effects). Reviewed-by: Andy Shaw

* Improved performance of translating device coordinate graphics effects.Samuel Rødal2010-01-131-0/+5
| | | | | | | | Don't invalidate the cache if we're only translating and the effect rect is fully contained within the device rect of the painter. Task-number: QTBUG-6901 Reviewed-by: Bjørn Erik Nilsen

* Optimized blur / drop shadow effects for the GL 2 paint engine.Samuel Rødal2009-12-141-7/+4
| | | | | | | | | Do the blur in half the resolution in software and then upload the result as a texture and smooth-scale it on the GPU. This leads to stable and decent performance regardless of the blur radius, and simplifies the implementation quite a bit. Reviewed-by: Bjørn Erik Nilsen
* Added InvalidateReason to invalidateCache to optimize effectsSamuel Rødal2009-12-141-3/+7
| | | | | | | | This lets us ignore the invalidateCache call when the transform of a graphics item with an effect changes, and the cached system is LogicalCoordinates and cached mode is not PadToEffectiveBoundingRect. Reviewed-by: Bjørn Erik Nilsen

* Fix redraw bugs when using graphics effects in device coordinate mode.Samuel Rødal2009-12-101-3/+11
| | | | | | | | | | QGraphicsEffect::boundingRectFor() needs the source bounding rect in device coordinates. This patch fixes the documentation to reflect this, and fixes some internal usage of boundingRectFor() to ensure it always gets the device rect of the source.

* Improvements to graphics effects API after review round.Samuel Rødal2009-11-101-90/+143
| | | | | | | | | | | | * Get rid of QGraphicsEffectSource from the public API, instead add convenience functions in QGraphicsEffect. This way we commit to less API, and are free to introduce a customizable QGraphicsEffectSource in a future release. * Move PixmapPadMode into QGraphicsEffect and tweak the names of the enum values. * Make QGraphicsBlurEffect::BlurHint into a bit flag, for extensibility.

| * | Fix for link error when building QtSvgGareth Stockwell2009-11-041-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building QtSvg for Symbian (ARMV5 build) fails due to the following linker error: QGraphicsEffectSourcePrivate::invalidateCache(bool) const (referred from qsvgwidget.o). This function is called from the inline destructor of QGraphicsEffectSourcePrivate. Making this destructor non-inline fixes the problem. It is not clear why QtSvg is instantiating this destructor, however, as neither QGraphicsEffectSourcePrivate nor any of its derived classes are referred to from QtSvg source. This problem seems to have been triggered by 85e41590. Reviewed-by: Shane Kearns

* | Removed pixelize, bloom and grayscale filterGunnar Sletta2009-10-231-449/+4
|/ | | | | | | | | | | | | | | | | This is new API and we don't want to add several items that are not strictly needed. This is a new set of features and we can grow them once we have more input from users on what is needed. The Bloom filter was added based on input from designers, but is not implemented according to how designers think of blook, so the effect doesn't meet the requirements. The Grayscale filter is functionally a duplicate of the colorize filter and is therefore not needed. The Pixelize filter has no genuine usecase. Reviewed-by: Samuel

* Fixed wrong use of graphics effects for pixmap graphics items.Samuel Rødal2009-10-141-27/+7
| | | | | | | | | | | The blur, drop shadow, and bloom graphics effects are scale dependent, since they have radius and offset (in the case of drop shadow) parameters that are specified in device coordinates. Thus, we can't apply the effect in logical coordinates and scale up, and need to always use the device coordinate path for these effects. The opacity and grayscale effects still use the logical coordinate optimization. Reviewed-by: Gunnar Sletta
