* Use the lazily-queried families for all QPA multi font engines.Pierre Rossi2012-03-141-0/+1
| | | | | | | | | This is the approach introduced together with the WebKit "backdoor" that lets us use QRawFont with QTextLayout. We could use it all over the place and share more code.

* Enablers for shared graphics cache in raster paint engineJiang Jiang2012-03-081-2/+2
| | | | | | | | | | | | Required changes for using shared graphics cache for distance field raster glyph rendering. Most of the logic is in platform plugins. Platform plugins should implement QPlatformIntegration::createImagePaintEngine() to create a subclass of QRasterEngine.

* Make cache of opentype tables in Harfbuzz face lazyEskil Abrahamsen Blomfeldt2012-03-061-5/+10
| | | | | | | | | | | | | | | | | | | | The mechanism in fontconfig which determines if a certain character is available (FcCharSetHasChar()) may give false positives, in which case we would load and unload those fonts per every char for which FC gave us a false positive. This was a major performance regression. Specifically the false positives happened when looking at e.g. italic variants of certain multilingual fonts, since we only check the charset of the font family as a whole and not of the specific variant, which may only support a subset of the chars. To optimize this, we remove the deletion of the font engines after loading them, but also wait with loading the opentype tables until they are actually needed. This means that for the false positives, we will load the font, but the cached data for each unused font will be much smaller.

* Avoid loading and keeping unused fallback font enginesEskil Abrahamsen Blomfeldt2012-02-171-2/+35
| | | | | | | | | | | | | | | | | | | | | | | | | When we request glyphs from fallback fonts, we would potentially load all fonts on the system into memory. This is especially true for glyphs that are not supported by any font (or by the last in the list) in any "Common" script (which e.g. includes CJK). This would make any application which tried to display unsupported glyphs use huge amounts of memory for keeping unused fonts cached, only limited by the number of fonts on the system. The patch contains two solutions: First, before loading the font, the multi font engine will be asked whether it needs to be tried for the given character. By default, this will always be true, so all fonts will be tried, but with the new font config multi engine in the platform plugin, it will ask FontConfig whether the font contains a glyph for the character. Should the font be loaded and still fail to resolve the character (which could be the case for other platforms), we will simply delete it again immediately instead keeping it cached.

* Move glyphMargin() to QFontEngineJiang Jiang2012-01-241-4/+4
| | | | | | | | | | | | | 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>

* Avoid double caching glyphs in raster/QPA/FreeTypeEskil Abrahamsen Blomfeldt2011-09-201-0/+40
| | | | | | | | | | | | | | | | | | | | | 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.
