* Add an image allocation pool to the OpenVG paint engineRhys Weatherley2009-12-158-53/+479
| | | | | | | | | | | | | Some OpenVG GPU's have limitations on the amount of memory available to create VGImage's. When the memory runs out, vgCreateImage() will fail. This change introduces QVGImagePool, which keeps track of all QVGPixmapData image allocations and ejects least-recently-used pixmaps when GPU memory is exhausted.

* Recreate VGImage properly in out of memory caseRhys Weatherley2009-12-091-0/+8
| | | | | | | | | If vgCreateImage() runs out of memory, then the drawPixmap() will fail. But previously, it would also prevent future attempts to call vgImageSubData() to populate the data when memory was present. Task-number: QTBUG-6639 Reviewed-by: Sarah Smith

| * Automatically destroy VG pixmaps when the last window surface goes awayRhys Weatherley2009-12-064-29/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Under S60, Qt will destroy the window surfaces of an application that goes into the background, which frees up EGL surface objects. But the VGImage's for pixmaps, and the EGLContext, were still using GPU memory. This change keeps track of the number of widgets / window surfaces that are in use and then calls hibernate() on all QVGPixmapData objects when it goes to zero. Once all the VGImage's are destroyed, the EGLContext should also be destroyed. Task-number: QT-2555 Reviewed-by: Sarah Smith

* Fix infinite recursion in OpenVG scissor-only clippingRhys Weatherley2009-11-271-12/+0
| | | | | | | | | | | When a complex transform was set, clip(QVectorPath) would call clip(QRect) with the control point rect, which would then turn around and say "transform is complex, call clip(QVectorPath)", causing an infinite loop until stack crash. Remove the "fall back to vector path" case as it isn't useful for scissor-only clipping. Doesn't affect mask-based clipping. Reviewed-by: Sarah Smith

This change passes the VGImage and size values in directly so that the composition helper can also be used to blit GL surfaces that have been converted into a VGImage via an EGLImage.

* 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.

* 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

| | | | | | | | | | | | | | 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

* 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.
