* The QFontEngineFT files are not built into QtGui anymore.Thiago Macieira2012-06-051-1/+1
| | | | | | | | | | | | | These files are only built into QtPlatformSupport, so the Q_GUI_EXPORT macro is now wrong. Remove it. Additionally, since these files are built into QtPlatformSupport, the windows platform plugin does not need to build them again.

* Fix FreeType glyph caching for high resolutionJiang Jiang2012-05-181-1/+1
| | | | | | | | | | | | | | | | | | | | For high resolution or extremely large font sizes, the advance cached here is likely to overflow, since FreeType returns 26.6 fixed point value and we only take signed char here for advance. In those cases we should skip caching because there won't be that many big glyphs after all. Also move the metrics caching block a bit down to take glyph embolden and oblique into account. As a result we also don't need to increase the linearAdvance size because any linearAdvance less than 128 should fit in the old 10.6 fixed format.

* Do not use charset loaded by fontconfigJiang Jiang2012-05-111-3/+0
| | | | | | | | | | | | | | | | | | The only use for storing charset loaded by fontconfig in font engines is for determine if a font supports certain codepoint, however FreeType already does that. The charset loaded is sometimes not complete, for instance in fontconfig 2.9.0 it removed Apple Roman platform support for cmap loading, thus results a regression in common symbol fonts (Wingdings, Webdings) rendering. Because those symbol fonts produced by Monotype only contain two cmap tables: Apple Roman and Microsoft Symbol, since the Microsoft Symbol table has a weird 0xF000 offset, we always fallback to the Apple Roman cmap table. Removing freetype charset cache also make each font engine consuming less memory.

* Avoid glyph rendering with FT when not neededJiang Jiang2012-05-041-1/+1
| | | | | | | | | | | | | | | | If we only need to access the font metrics (like in scenegraph) for layout, we don't need to render glyphs with FreeType at all. Increase cached linearAdvance to 22 bits so that no overflow will happen: FreeType returns 16.16 fixed point linearHoriAdvance, but QFixed is 26.6, we store glyph->linearAdvance = linearHoriAdvance >> 10 Apparently 'short' is not enough since it's only 16 bits.

* Avoid loading and keeping unused fallback font enginesEskil Abrahamsen Blomfeldt2012-02-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* Avoid double caching glyphs in raster/QPA/FreeTypeEskil Abrahamsen Blomfeldt2011-09-201-1/+6
| | | | | | | | | | | | | | | | | | | | | 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.
