* Use vgClear() to clear the background during screen compositing.Rhys Weatherley2009-10-271-18/+46
| | | | | | | | This fixes an "off by 1" bug in screen compositing with OpenVG that left lines all over the background when windows were moved. Task-number: QT-2322 Reviewed-by: Sarah Smith
* Optimize QVGPixmapDropShadowFilter by removing colorize stepRhys Weatherley2009-10-193-52/+25
| | | | | | | | | | | | | Previously, the drop shadow was colorizing the incoming image and then blurring the colorized version. This change first blurs the image to an alpha-only VGImage and then uses that VGImage as a stencil to draw the drop shadow color. This way, there is only 1 filter step and a draw instead of 2 filter steps and a draw. The result is to make the performance of the drop shadow filter almost identical to the blur filter.

| * qt_paint_device_metric() for fetching metricsRhys Weatherley2009-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | Custom window surfaces, graphics systems, and Qt/Embedded screen drivers often need to access QPaintDevice::metric(), but it is protected. Hence the growing number of friends in QWidget and QImage. The qt_paint_device_metric() function provides a more future-proof approach that doesn't require lots of friends. Reviewed-by: Gunnar

* Make it possible to implement engine-specific drop shadow filtersRhys Weatherley2009-10-052-30/+17
| | | | | | | | | | | | It wasn't possible for the paint engine to override the drop shadow filter because QPixmapDropShadowFilter::draw() was not asking for an engine-specific filter object. Also, change the OpenVG filter to use vgGaussianBlur() instead of vgConvolve(), and draw the original image on top of the shadow. Task-number: QTBUG-4583 Reviewed-by: trustme
* Make QPF's implementation of alphaMapForGlyph() consistent.Rhys Weatherley2009-09-291-14/+0
| | | | | | | | | | | | | | The QPF implementation of alphaMapForGlyph() was returning color values of RGBA = (a, a, a, 255) instead of (0, 0, 0, a), which was inconsistent with all the other font engines. This inconsistency caused some QPF-specific workarounds in the OpenGL and OpenVG paint engines. This change removes the workarounds and makes QPF generate the right colors from the start. Paint engines that ignore the color table or which don't use the alphaMapForGlyph() function (e.g. raster) are not affected. Reviewed-by: Paul

* Push the "lazy doneCurrent" logic down from QtOpenVG into QEglRhys Weatherley2009-09-243-108/+29
| | | | | | | | | | | | | | QtOpenVG was doing a lot of housekeeping to avoid having to switch EGL contexts if the same surface was used over and over. This housekeeping really belongs in the QEgl layer so that QtOpenGL could potentially use it as well. This change also adds some overrides for makeCurrent(), swapBuffers(), and destroySurface() that take an EGLSurface directly. This is the first step in separating EGL surface management from context management. Reviewed-by: Sarah Smith
* Fix cubic paths in OpenVGRhys Weatherley2009-09-231-3/+3
| | | | | | | | | | The multitouch/dials example was displaying rendering artifacts on the dials in the default style. This was due to incorrect VGPath construction when sizeof(qreal) == sizeof(VGfloat). It was adding two VG_CUBIC_TO_ABS elements per cubic instead of one. Task-number: QT-2035 Reviewed-by: Sarah Smith
* Avoid calling ensureContext() in setGeometry.Jason Barron2009-09-231-1/+0
| | | | | | | | | We can delay calling ensureContext() since it will happen when painting begins anyway. There is a chance that we can get to this function when a window is being hidden and if this is the first thing that happens in the application, there is no need to call ensureContext() yet.

* Modify functions for native pixmap data conversion on Symbian.Jason Barron2009-09-232-129/+141
| | | | | | | | | | | | | We need a way to support converion to and from multiple native pixmap types from multiple pixmap backends. Instead of adding more virtual functions to QPixmapData, make the existing one more generic but pass an opaque pointer and a type and do some internal casting. Currently this function is Symbian only, but could easily be extended to work on other platforms. Reviewed-by: Aleksandar Babic Reviewed-by: Jani Hautakangas

* Reduce overhead of paint engine-specific pixmap filtersRhys Weatherley2009-09-162-12/+28
| | | | | | | | | | | | | | | | | | | Engine-specific pixmap filters were being created, used, and destroyed every time draw() was called on QPixmapColorizeFilter, QPixmapBlurFilter, and so on. This had a heavy performance penalty and made it difficult for the GL paint engine to cache shaders from one request to the next. A generic filter can request an engine-specific filter that matches its parameters. The engine can either create a new one or return a previously allocated filter object. Ownership of engine-specific pixmap filter objects is moved to the paint engine itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the Mac, it means "-framework ApplicationServices -framework Carbon -framework AppKit" are no longer part of the default LIBS in Qt applications.

I haven't changed the Windows-specific LIBS paths, because I don't know how Windows behaves. Windows has DLLs, but it links to static "import" libraries. So is it static linking or dynamic linking?
