* Allow QDistanceField to be directly constructed from a QPainterPath.Michael Brasser2015-02-251-0/+11
| | | | | | | | | | Enables optimization in the case of an already existing QPainterPath.

* Use C++ <cmath> instead of <math.h>Allan Sandfeld Jensen2015-02-161-3/+3
| | | | | | | | | | | | | | Including math.h can pollute the default namespace, and break some compilers if cmath versions of the method are declared as using. Switching to C++ math functions also greatly simplifies handling of float qreal as C++ automatically chooses the right method. [ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any sources depending on that indirect inclusion may fail to build.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>

| * QDistanceField: a zero glyph index means the glyph was not foundShawn Rutledge2014-11-251-1/+1
| | | | | | | | | | | | | | | | | | | | In qt_fontHasNarrowOutlines, if we proceed to call alphaMapForGlyph when the glyph does not exist, there will be a failed assertion. The docs for FT_Get_Char_Index say that zero means the glyph was not found. Change-Id: I371e9a2797a34fa3ebeae44531af51e24dadad79 Reviewed-by: Konstantin Ritt <ritt.ks@gmail.com>

* | Add Grayscale8 and Alpha8 formats to QImage and drawingAllan Sandfeld Jensen2014-09-171-2/+3
|/ | | | | | | | | | | | Extend the QImage format with two 8-bit grayscale and alpha formats. These formats have the advantage over Indexed8 that they have simpler conversion and can be rendered to by the raster engine. [ChangeLog][QtGui][QImage] Added support grayscale and alpha 8-bit formats which can also be rendered to.

* Optimize stringToCMap() usageKonstantin Ritt2014-02-071-4/+10
| | | | | | | | | | | | CMAP guarantees there is 1:1 mapping between the Unicode code points array and the glyph indexes array, which means the QString length always greater than or equal to a sufficient glyph indexes array length. Simply add some asserts and improve the memory consumption and the performance where possible. Change-Id: I0bc8cdba5f86c1c0ba9e79c8d5f96cbe56ec463e Reviewed-by: Lars Knoll <lars.knoll@digia.com>
* Use custom class for storing distance fields instead of QImage.Yoann Lopes2013-08-271-27/+243
| | | | | | | | | | | | | | | Distance fields are stored using a one-byte alpha component per pixel, a format that QImage doesn't currently support. The Indexed8 format was used instead, limiting what could be done with the QImage. This patch introduces a new private class, QDistanceField, with a similar API to QImage and using the Alpha8 pixel format. Unlike QImage which aligns scanlines on a 4-byte boundary, QDistanceField tightly packs scanlines together.
