* Improved performance of 16 bit memrotates using NEON instructions.Samuel Rødal2010-07-011-22/+2
| | | | | | | | | | | Make the memrotate functions a function pointer table so that we can replace it with optimized versions, and implement an optimized NEON version for the 90 and 270 rotations. Measured performance improvement for a 400x400 16-bit pixmap was 17 % for 270 degree rotation and 11 % for 90 degree rotation. Reviewed-by: Trond

| * | Make QStaticText private APIEskil Abrahamsen Blomfeldt2010-02-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Turns QStaticText into private API in preparation for Qt 4.6.x. The related functions in QPainter are marked as internal in the docs. There are already internal functions in QPainter, so this seemed like a reasonable solution. Since the functions require QStaticText they will not be accessible to anyone who does not include private API.
| * | Implement drawStaticTextItem() in OpenGL paint enginesEskil Abrahamsen Blomfeldt2010-01-141-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OpenGL and OpenGL2 engines now have support for static text, as well as the QEmulationPaintEngine. Also contains an optimization: Instead of passing both the position and glyph positions to drawStaticTextItem() we add the position into the glyph position and update it only when it changes. Otherwise we would have to do this work in all engines for every call. This means we have to cache the position in QStaticTextPrivate as well, but it seems like a small price to pay, since it's a per-text overhead and only 16 bytes.
| * | Support transformations in drawStaticText() and optimize for spaceEskil Abrahamsen Blomfeldt2010-01-141-18/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Support transformations on the painter in drawStaticText(). Transforming the painter will cause the text layout to be recalculated, except for translations, which are handled by shifting the position of the text items. 2. Make const length arrays of the internal data in QStaticTextItem in order to minimize the memory consumption.
| * | Optimize QStaticText for spaceEskil Abrahamsen Blomfeldt2010-01-141-14/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By caching the results of getGlyphPositions() we can make a code path in the critical paint engines which is optimal both in space and speed. The engines where speed is of less importance (pdf engine etc.) which may need more information, we choose the slower code path of drawText() which lays out the text again. We should have optimal paths in raster, vg and GL2 paint engines. The others are less important. Memory consumption of static text is now 14 bytes per glyph, 8 bytes per item and a static overhead of 40 bytes per QStaticText object.

* | Fixed text rendering via scaled QPainter on rasterPaintEngine / SymbianAlessandro Portale2010-02-011-1/+8
|/ | | | | | | | | | | | | | | | | | | | | | | | | Text rendering in Qt for Symbian looks very bad on a scaled QPainter. Instead of simply using a Symbian font with the right size it followed the code path that is usually used for "tricky transformation": Use the glyph outlines and rasterize them in Qt as QPainterPath. That's slow and especially ugly on Symbian since we do not (yet) get the glyph outlines from Symbian. This patch adds QFontEngineS60::setFontScale() so that QFontEngineS60 has one additional native font handle with the scaled size. The raster paint engine will call that function in case that the painter is scaled. Since we already have QFontEngineS60 specific code in the raster paint engine, this patch did not have to add #ifdefs. http://bugreports.qt.nokia.com/browse/QTBUG-7614 Task-number: QTBUG-7614 Reviewed-by: Jason Barron modified: gui/painting/qpaintengine_raster.cpp modified: gui/text/qfontengine_s60.cpp modified: gui/text/qfontengine_s60_p.h

| | | | | | | | | | | | | | | | | | | | | | | | | | Since the width is multiplied into the dash, it needs to be divided out, otherwise you can get a dashOffset which is greater than the pattern at the index, and the dash can become negative. This will in turn lead to passing a negative width to the rasterizer, which at some point will get cast to an unsigned int and overflow. Depending on the position of the line and size of the buffer, this will either crash or produce garbled output. Task-number: QT-4444 Reviewed-by: Samuel
