* Correct last right bearing in boundingBox(glyphs)Jiang Jiang2010-08-271-8/+9
| | | | | | | | | | | | | | | | | | Commit 07880542ecc479807c23c5646d263135240822ff introduced regression to QFontMetrics::boundingRect and QTextEngine::boundingBox on FT, XLFD and QPF font engine. Because on these platforms, rightBearing of the last glyphs is already removed from the width returned in glyph_metrics_t. Subtracting that rightBearing twice will cause the resulting boundingBox smaller than expected. This patch fix this by removing last right bearing accounting code from generic QTextEngine::boundingBox, instead, we put it into font engines that need them: QFontEngineWin, QCoreTextFontEngine, QFontEngineMac, QFontEngineS60 and QFontEngineQWS. So that the resulting width should be correct on all platforms without introducing any performance penalties. Task-number: QTBUG-6854, QTBUG-12950 Reviewed-by: Eskil

* Fix glyph advance on Mac/CarbonEskil Abrahamsen Blomfeldt2010-03-251-10/+43
| | | | | | | | | | | | | Device metrics was turned on for Mac/Carbon to work around a bug in WebKit that required the font engine to report only integer values. This in turn caused positioning of glyphs to be slightly off compared to native applications. The bug has been fixed in WebKit, so now we can turn off the device metrics flag. Since we are now reporting fractional values as well, we need to round the numbers when the ForceIntegerMetrics style strategy flag is set. Task-number: qtbug-5529 Reviewed-by: Trond
* Add QFont::ForceIntegerMetrics style strategy flagEskil Abrahamsen Blomfeldt2010-03-241-10/+39
| | | | | | | | | | | | | | | | | | | WebKit uses integers internally to deal with positioning and sizing of text objects, but on Mac, Qt uses floating point values. This caused a discrepancy between the size used by WebKit to position text objects and the actual size of the objects when rendered by Qt. The problem was so bad that it has been holding back fixes for other bugs in the mac font engine since these would make the WebKit bug more visible. To work around the problem, we introduce a StyleStrategy flag in QFont which allows you to force the use of integers all over the line. This makes text rendering slightly different from native applications, but should fix several issues with WebKit on Mac. The WebKit-part of this patch will be submitted up-stream.

* Cocoa: Fix misaligned text between format changesEskil Abrahamsen Blomfeldt2010-03-101-1/+1
| | | | | | | | | | | | | | | | | | | This reverts part of commit e008504b5ec34975e34adf3b1a2b7170d0e4dd38. The original commit aimed to round up all fractional numbers for the font to "improve appearance". Rounding up the last advance of a set of advances in a glyph layout, however, breaks text layout completely, since the layout of text will be different depending on how many text lines is used to represent it (since the last glyph in each line will have a higher advance than the others.) This was e.g. visible in Qt Creator when turning on whitespace visualization, as all spaces then created a format change, thus a new text line in the text layout, and hence an increase of X pixels in the positioning of the text after the space, where 0.0 < X < 1.0. I see no negative results of removing the rounding, but if there are any problems, it has to be fixed in the usage of the advances not in the advances themselves.

* Fix vertical text centering on Mac OS XEskil Abrahamsen Blomfeldt2009-12-151-2/+6
| | | | | | | | | | | | | | Change 04d18b38 fixed the windows and ft font engines so that the height reported in QFontMetrics is now correct, but this make vertical text centering one off as the platform defaults is to round down rather than up when the vertical position of the text is in the middle of a pixel. When this was fixed in change 1de8a5b, the vertical centering broke on Mac, since it still reported a too great font height. This patch applies the same hack to the mac font engines to report the correct font height. Task-number: QTBUG-6770 Reviewed-by: joerg
