* Better handling of invalid font tablesHEAD4.8Eskil Abrahamsen Blomfeldt2015-10-231-1/+1
| | | | | | | | | | | | | | | Specifically when reading files with broken cmap tables, we could get some undeterministic results. We handle this more gracefully by verifying that the offsets are sane and bailing out early if not. This replaces the current pattern throughout the font engine for consistency. This is a back-port of 4a1e5dbade4bab55f39bd368480dcca9a11e4b38 from Qt 5.

* Make QtQuick2 compile on QPAEskil Abrahamsen Blomfeldt2011-04-271-0/+2
| | | | | | | | | | | 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
* Long live QRawFont!Eskil Abrahamsen Blomfeldt2011-04-151-4/+1
| | | | | | | | | | | | | | The QGlyphs API was initially attempted with a bastardization of QFont which was meant to encapsulate a single, physical font instance (a QFontEngine) where a set of glyph indexes would make sense. This is not how QFont was intended to be used, and it caused several issues. At the same time, the requirement for loading a font from ttf/otf data and be able to access it and use it without polluting the rest of the process with the font arose. To support these two APIs we introduce QRawFont, which is an abstraction on top of a single physical font. Done-with: Jiang Jiang
* Fix positioning in GL2 paint engine with subpixel antialiasingJiang Jiang2011-04-041-1/+1
| | | | | | | | | | | | In this case we will use QTextureGlyphCache with FreeType renderer, which requires the subpixel positition to get correct left bearings, thus alphaMapBoundingBox is extended to support subPixelPosition. In QFontEngineFT we also simplify the code a bit by reusing loadGlyphs for metrics calculation instead of duplicate code. Since we need to use the glyphs after all, cache them here in alphaMapBoundingBox shouldn't be a problem. Reviewed-by: Eskil
* Introduce QFontEngineDirectWriteEskil Abrahamsen Blomfeldt2011-03-141-0/+2
| | | | | | | | | | | | | | | | Make a font engine for subpixel positioned text on Windows Vista (with platform update) and Windows 7. If selected during configuration, the engine will be selected only when the hinting preference of a font is set to None or Vertical hinting. The font database uses most of the same logic but creates a direct write font based on the LOGFONT rather than a GDI handle. The engine is currently regarded as experimental, meaning that code using it should do substantial testing to make sure it covers their use cases. Task-number: QTBUG-12678 Reviewed-by: Jiang Jiang

| * | Support sub pixel positioning of glyphs in raster engineEskil Abrahamsen Blomfeldt2010-09-091-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the raster engine to provide the same quality of text rendering as the native engine on Mac Cocoa, we need to support rendering to different sub pixel positions for each glyph. The number of subpixel positions is arbitrary and has to be detected, but it's usually three or four. Each position will give slightly different coverages inside the pixel and thus different rasterizations. Other font engines which support sub pixel positioning of glyphs can provide the same functionality by implementing supportsSubPixelPositions() to return true, and then adding the subPixelPosition argument to the x coordinate used in alphaRGBMapForGlyph().
