| * Don't rely on uninitialized dataJoão Abecasis2011-05-031-0/+1
| | | | | | | | | | | | | | | | | | | | HB_GetCharAttributes used to require a zero-initialized array for attributes, as it selectively sets relevant bits for each character. We ease that requirement by always initializing the attributes buffer explicitly with memset. Task-number: QT-4911 Reviewed-by: Ritt Konstantin
* | Implement subpixel positioning with FreeTypeJiang Jiang2011-03-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QFontEngineFT are used in raster/OpenGL paint engine and QGLWidget, also in Symbian, etc. We want to make sure it works well in raster and QGLWidget first. Regardless subpixel antialiasing (LCD filtering) is enabled or not (though it does look better when subpixel antialiasing is on). We also need to support transformations. The tricky part here is that, under X11, we have a different code path for QFontEngineFT and other font engines in raster engine, which uses QFontEngineFT's own glyph cache system. While in other platforms (Windows and Mac) and QGLWidget, we will use the generic QTextureGlyphCache. The generic QTextureGlyphCache already has support for subpixel positions, this solution is ported to QFontEngineFT for its QGlyphSet: the key for QGlyphSet hash table has been extended from glyph_t to <glyph_t, QFixed subPixelPosition> pair. The real work to enable subpixel positioning with FreeType is in fact really simple, we just set the horizontal translation to the subpixel position * 64 (FreeType uses a coordinate system of 1/64 of a pixel resolution internally) immediately before loading the glyph. A slight tweek to bitmap width is applied when we are getting the bitmap ourselves instead of using FT_Render_Glyph to accommodate the subpixel translation, which will only be used in non-LCD filtering cases (grayscale antialiasing). From what we have observed, FreeType can generate different bitmaps for at least 12 different subpixel positions (each with a slight difference). To limit the memory consumption, we restrict the number of subpixel positions to be 4 (hardcoded), which should be good enough for most low resolution displays. Subpixel positioning (and fractional glyph advances) will only be enabled when the hintingPreference for the font being used is PreferNoHinting or PreferVerticalHinting. We will use fontconfig hintstyle setting by default when no hintingPreference is set for the font. Task-number: QTBUG-12279 Reviewed-by: Eskil

* | Fix combining marks shaping without GPOS feature in HarfBuzzJiang Jiang2011-03-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | For certain OpenType fonts like DejaVu Sans Mono, not all combining marks has GPOS feature applied, U+0062 U+0332 is one of the case. Only getting the advances for indivivual glyphs is not enough, we should also do heuristic positioning to put the combining mark in the right place. Task-number: QTBUG-15675 Reviewed-by: Lars Knoll

* | Disable certain GPOS features by defaultJiang Jiang2010-12-201-6/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to OpenType Layout tag registry, these features should be turned off by default. Leaving them on will cause some text layout problems in common UI widgets -- they are usually designed for better positioning in print publishing or full featured text layout programs, not for general usage. There is no way to turn them on in HarfBuzz now, it should be addressed later. Features like 'valt' are intended for vertical writing mode are also turned off, since HarfBuzz doesn't support it properly yet. Task-number: QTBUG-15754 Reviewed-by: Lars Knoll
