| * Avoid OpenVG rendering errors when stroking an aliased path.Jason Barron2010-09-231-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Stroking a path can sometimes result in inconsistent rendering especially when combined with a clip. For example, if the logical edge of a clip rect coincides with the logical edge of a path then it can happen that the edge is not painted correctly because the stroke lies outside the bounds of the clip rect. To workaround this problem, we add the 'aliasedCoordinateDelta' such that the rounding will err on the side of caution. This improves the correctness when using the raster engine as a reference.

| * Fix crash in OpenVG when failing to allocate large VGImages.Jason Barron2010-09-101-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reclaimSpace() function of the VG image pool was crashing when attempting to free up space for a large image. It was calling moveToHeadOfLRU() which adds the image to the pool. If the pixmap is large enough so that it pushes all the others out, then it will be the only pixmap left in the pool when this function returns. This is problematic because this pixmap is not permanent so it could be deleted. If that happens, then subsequent calls to this function will crash because the LRU pixmap has been deleted. The fix is to check if the pixmap was in the pool to begin with and if not, then be sure to remove it before returning from this function. Task-number: QT-3652 Reviewed-by: Jani Hautakangas

| * Improving text coordinate rounding in the OpenVG paint engineAlessandro Portale2010-08-041-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b0bbabe728fedb8531fc2837403856bd5ed44e1b fixed text blurriness in the OpenVG paint engine by forcing the coordinates of the text items to integer coordinates (for unrotated, unscaled text). That was not yet enough. In addition to the coordinates, also the d->pathTransform in QVGPaintEngine can have a non-integer translation. This patch makes sure that the text item coordinate combined with the translation result in final integer coordinates. Since it is not possible to set an absolute translation of a QTransform (only relative is possible), first dx() is added to p.x(), then after rounding, it is again substracted. Sam for y, but with opposite prefix, since the y-axis in Qt and in transformation matrices are in opposite directions. The ceil stunt (which I cerated by trial and error) was replaced by floor(x + aliasedCoordinateDelta), which *exactly* what other paint engines do. Task-number: QTBUG-12330 Reviewed-by: Jason Barron
| * Fix proxy widgets with the OpenVG paint engine.Jason Barron2010-07-301-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Proxy widgets use the shared painter functionality and this implies that the paint engine's begin function does not get called for each new widget that gets painted. This causes a problem because the system clip gets modified by QPainter, but the paint engine does not realize that this happened and fails to use the new clip. The result is that you can end up painting outside the intended clip area. The fix is to reimplement the virtual systemStateChanged() function in QVGPaintEnginePrivate and make it call updateScissor() to re-evaluate the clipping flags and update the current clip accordingly. A similar fix was done to the OpenGL paint engine way back in 307c2954. Task-number: QTBUG-12486 Reviewed-by: Rhys Weatherley

| * Avoid a crash in the OpenVG paint engine when clipping to an empty pathJason Barron2010-07-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The convertToPainterPath() function assumes that the QVectorPath contains at least one path element when creating the QPainterPath. This is not necessarily the case here though because if QVG_SCISSOR_CLIP is defined and setClipPath() is called with an empty QPainterPath, this is then converted to an empty QVectorPath in QPaintEngineEx::clip() which then calls QVGPaintEngine::clip(). This function then goes on to convert the QVectorPath back into a QPainterPath using the aforementioned function which crashes when attempting to access the first element of the path. In case you are wondering why this seemingly redundant conversion happens at all, it happens because when QVG_SCISSOR_CLIP is defined, we attempt to convert the path to a series of rects for scissor clipping and this conversion function operates on QPainterPath instead of QVectorPath which is what this clip() function was designed to deal with. The fix is to skip over the path conversion for empty paths and go directly to an empty QRegion. Reviewed-by: Alessandro Portale

| * Avoid blurry text with OpenVG on SymbianAlessandro Portale2010-06-301-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qt's graphics system uses qreal as measurement unit. The established paint engines (such as "raster") implicitly round textitem coordinates for technical reasons, e.g. for optimized blitting. Some Qt based Ui libraries (such as QWidgets) can in some cases cause textitems to be drawn on non-integer coordinates. In particular, this happens when centering text. Since these libraries have been developed against the established paint engines with implicit rounding, these non-integer coordinates were never an issue. The new OpenVG paintengine took these coordinates seriously without rounding them. On some OpenVG implementations (e.g. that of some Symbian phones), this led to blurry text rendering. This patch adds coordinate rounding for unscaled, unrotated textitems to the OpenVG paintengine. So that it does the same as the raster paint engine. Task-number: QT-3071 Reviewed-By: Jason Barron

* | Ensure glyphs are upright instead of upside-down.Jason Barron2010-07-123-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OpenVG paint engine traditionally takes glyph images from the alphaMapForGlyph() function which returns the glyph image in the upright projection. When it constructs a VGImage from this image, it passes a positive data stride which will read the top scanline of the source image into the bottom scanline of the VGImage due to the VG coordinate system. It then uses the path transform where the 'sy' value of the matrix is set to -1 and this re-inverts everything when drawing. With the Symbian based glyph cache, the VGImage is constructed from a RSgImage which is a hardware resource and compensates for the coordinate system used by VG and GL at the time it is created. In the case of the hardware glyph cache, the glyph image is read into the RSgImage using a negative data stride so it does not need to be inverted when drawn. To allow for this, introduce a flag which indicates that the 'sy' entry of the matrix should be flipped such that the glyph is drawn normally. Also in this patch is a change to the glyph origin which now uses the bottom of the glyph metric bounding rect instead of the top due to orientation of the glyph inside the VGImage.

| | | | | | | | | | | | | | | | | | | | | | This introduces a specialized OpenVG font cache for the Symbian platform. By using RGlyphDataIterator we can create a VGImage to store inside a VGFont without having to upload our own glyph image. This works by utilizing RSgImage which can be used to share handles to graphics memory across processes thus allowing glyph images to be shared by multiple processes and reducing graphics memory usage.

| * Clipping with rounded rectangles and QVG_SCISSOR_CLIPRhys Weatherley2010-06-021-4/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | WebKit draws rounded rectangles by setting a rounded rect path as a clip and then filling the clip. This had problems when QVG_SCISSOR_CLIP was enabled because the scissor would only clip to the bounding box of complex paths. Thus, rounded rectangle clips were turned into normal rectangle clips. This change will make the scissor clipping code subdivide complex paths into rectangles and use a tighter clip if the number of rectangles is less than or equal to VG_MAX_SCISSOR_RECTS. If it is greater, then it will fall back to the bounding box of the path. Task-number: QT-3372 Reviewed-by: Jason Barron
