* Improved performance of translating device coordinate graphics effects.Samuel Rødal2010-01-131-0/+2
| | | | | | | | 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

* Added InvalidateReason to invalidateCache to optimize effectsSamuel Rødal2009-12-141-1/+10
| | | | | | | | 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

* Improvements to graphics effects API after review round.Samuel Rødal2009-11-101-3/+38
| | | | | | | | | | | | * 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.

| * Add QT_NO_GRAPHICSEFFECTJørgen Lind2009-11-041-0/+2
| | | | | | | | | | | | | | It depends on QT_NO_GRAPHICSVIEW for now, but it is possible to remove this dependency. Reviewed-by: paul
* | Fix for link error when building QtSvgGareth Stockwell2009-11-041-1/+1
|/ | | | | | | | | | | | | | | | | 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
* Optimized graphics effects to not needlessly invalidate cache.Samuel Rødal2009-11-021-1/+1
| | | | | | | When the effect rect changes we only need to invalidate the cache if the mode is ExpandToEffectRectPadMode. Reviewed-by: Gunnar Sletta
* Added some optimizations to the blur and drop shadow GL filters.Samuel Rødal2009-10-291-1/+7
| | | | | | | | | | | | | | | | | | | | * Use ExpandToTransparentBorderPadMode since we can use GL_CLAMP_TO_EDGE to clamp to the texture. * Shrink the bounding rects reported by the blur and drop shadow filters (expanding by 2 * radius isn't needed). * Use a single-pass blur for radii <= 3 to avoid the overhead of rendering to an FBO. * Made the fast blur setting generate filters for only a predefined set of radii, and then use the actual blur radius to spread the sample points outwards. * Optimized the generated program to rely less on temporary variables, as those seemed to not be handled very well by certain GLSL compilers.

* | Removed pixelize, bloom and grayscale filterGunnar Sletta2009-10-231-37/+0
|/ | | | | | | | | | | | | | | | | 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
* Added caching of graphics effect source pixmaps to speed up effects.Samuel Rødal2009-10-221-1/+11
| | | | | | | If an effect is applied repeatedly on the same source, just with varying parameters, we can save a lot by caching the source pixmaps. Reviewed-by: Bjørn Erik Nilsen

* Make sure the BSP is updated when a graphics effect changes bounding rect.Bjørn Erik Nilsen2009-09-011-0/+1
| | | | | | | | | In the case of applying an effect to a QGraphicsItem, we have to notify the scene's BSP that the item's bounding rect has changed. We do this by calling prepareGeometryChange(). In the case of QWidget, it's sub-optimal that we update its parent, but there's no other way to solve it at the moment.
