* Remove platform specific DirectWrite font engine from QtGuiEskil Abrahamsen Blomfeldt2012-07-031-698/+0
| | | | | | | | This has moved into the platform plugin, but it was still lying around in QtGui and hindering it from compiling. Change-Id: I47fa730453cbd8aa230ccc4651afd2e774023db6 Reviewed-by: Jiang Jiang <jiang.jiang@nokia.com>
* DirectWrite font engine: don't leak the font table bufferKonstantin Ritt2012-07-031-13/+11
| | | | | | | | | | | Ideally, each TryGetFontTable() call sequence should be followed by the call to ReleaseFontTable() with the context value taken from the first TryGetFontTable() call, otherwise we'll leak the buffer allocated for the font table.

* Deprecate qMemCopy/qMemSet in favour of their stdlib equivilents.Robin Burchell2012-04-111-2/+2
| | | | | | | | | | | | | | | | | | Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these functions just to avoid an include, except to pay for it with worse runtime performance. On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15% faster(!) than adding an additional call to qMemSet. The advantage on sizes above that is unmeasurable. For qMemCopy, the benefits are a little more modest: 16-7%.

* Remove historical +1 from font height calculationEskil Abrahamsen Blomfeldt2012-02-171-2/+2
| | | | | | | | | | | Historically, we've calculated font height as ascent+descent+1. In Qt 4, a patch was added to work around this by subtracting 1 from the descent of the font engines. We now remove the +1 and the work arounds.

| | | | | | | | | | As in the past, to avoid rewriting various autotests that contain line-number information, an extra blank line has been inserted at the end of the license text to ensure that this commit does not change the total number of lines in the license header.

* Move glyphMargin() to QFontEngineJiang Jiang2012-01-241-2/+3
| | | | | | | | | | | | | glyphMargin() support for QTextureGlyphCache is implemented in respective font engines, thus this function is platform dependent. Before Qt 5 the code is guarded in macros like #ifdef Q_WS_MAC, now we should move them into QFontEngine and its subclasses. So far only Windows font engines support it. FreeType and Core Text based font engines all ignore it. Change-Id: Ia14016533d8fbfaacf848a7d3bc928f8197318f5 Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@nokia.com>

* Fix transformations on DirectWrite rasterized textEskil Abrahamsen Blomfeldt2011-07-011-46/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | There were a few bugs in the DirectWrite font engine that caused transformed text to break. First of all, alphaMapForGlyph() ignored the transform, so no gray antialiased text would be transformed. Second of all, the imageForGlyph() function would use the wrong bounding box for the rasterized glyph, causing its positioning to become a little bit off when rotating. The fix is to get the bounding box from the system and add a margin to this instead of trying to predict how it will appear after the vertical hinting etc. has been applied. So that the positioning metrics are in sync with the actual metrics used by the alphaMap* functions, we also need to implement the alphaMapBoundingBox() function.

* Make QtQuick2 compile on QPAEskil Abrahamsen Blomfeldt2011-04-281-0/+11
| | | | | | | | | | | Moved the logic to set pixel size into the font engines to avoid making the platform plugin interface too complex, and added a function in QPA to make an isolated font engine based on font data. Currently none of the QPA back-ends supports it, but it compiles and spits out a warning if you try to create a QRawFont from data there. This isn't used in QtQuick2 anyway. Reviewed-by: Jiang Jiang
