* Don't render glyph with FT with fetchMetricsOnlyJiang Jiang2012-02-171-1/+1
| | | | | | | | | Neither rendering with outline nor fetchMetricsOnly requires the rendering from FreeType so we don't need to render them or cache it. It should speed up recalcAdvances() quite a lot. Change-Id: I0f623cb4f79da2edf6e9c9634a2f22fb0c66823c Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com>
* Remove historical +1 from font height calculationEskil Abrahamsen Blomfeldt2012-02-171-3/+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.

* Fix scaled text rendering with the raster paint engine & FreeTypeSimon Hausmann2011-10-171-0/+7
| | | | | | | | | | | | | | | Before commit 070d9c00c488a5ee6811f04170cf488ead79bf80, the raster paint engine used to call loadGlyphs() on the FT engine, which ensures that the glyphs are loaded and (more importantly) that the correct transformation matrix is applied on the freetype face. After commit 070d9c0 lockedAlphaMapForGlyph is called for each glyph, which unfortunately doesn't respect the provided transformation matrix. Therefore when drawing scaled text, it was never actually scaled. This patch applies the combination of the fontengine transform and the requested transform on the freetype face actually used, similarly to loadGlyphs.

* Avoid double caching glyphs in raster/QPA/FreeTypeEskil Abrahamsen Blomfeldt2011-09-201-15/+86
| | | | | | | | | | | | | | | | | | | | | Since FreeType has internal caching, it has had a special code path in the raster engine which avoided using Qt's glyph cache, as that would be redundant. However, when compiling with QPA, we want the same behavior without being able to access the QFontEngineFT class. To achieve this, I've made a new abstraction and added it to QFontEngine which allows the FT engine to provide direct pointers into the alpha maps stored by FT. This requires a locking/unlocking mechanism. Yes, the QFontEngine::alphaMap* API is slowly becoming a horrible mess, but due to time constraints, the task of refactoring these functions into a more flexible API needs to wait. I've added a TODO comment for this.

* Fix regression causing synthesized oblique glyphs to clipEskil Abrahamsen Blomfeldt2011-09-191-1/+15
| | | | | | | | | | | | | | | | | In 20009ed797fb30952a889df5716aa2399102be58 I introduced a new approach to synthesized oblique. However, while the embolden function in FT alters the glyph metrics accordingly, the oblique function does not, so the glyphs would be clipped to the original, unslanted metrics. So I've implemented the same matrix in the loadGlyph() function and we now apply this to the metrics manually. This will only work as long as the underlying algorithm doesn't change significantly.

* Allow selecting fonts with irregular style namesJiang Jiang2011-06-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fonts like "Helvetica Neue UltraLight" or "Skia Regular Black Condensed" can't be selected in Qt because either they don't report correct numeric values for weight/stretch/etc. or these values are not mapped from QFont enums in a linear way. Thus we provide a shortcut to select these fonts with PostScript name or full name without resorting to family name matching in QFontDatabase (these fonts are not registered in font database anyway). After this, we can simply use: QFont font("Helvetica Neue"); font.setStyleName("UltraLight"); to select these fonts. QCoreTextFontEngineMulti matched like this can be created directly from the CTFontRef instance instead of creating from the font name, making this process faster. The commit also cleaned up the font loading process in Mac font database a bit, moving the code for family matching into a separate function. Add QFontInfo::styleName() and QRawFont::styleName() to access the resolved style name for a font.

| | | | | | | | | | | | | In FreeType, there's a fall back to QFontEngine::alphaMapForGlyph() when the fonts are very large. Since this uses a QPainterPath containing an unhinted glyph, the use of hinted metrics would sometimes lead to the glyphs being clipped because they would be positioned slightly outside the image they were painted into.
