* Enabler for fractional scaling of text in Qt QuickEskil Abrahamsen Blomfeldt2022-06-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | As opposed to the raster engine, in Qt Quick we are using unscaled positions for the glyphs and using the vertex shader to scale these after the fact. However, when picking the correct subpixel rendering for each glyph, we would use the unscaled position's fractional part, meaning that we essentially rendered the glyphs at the wrong subpixel position. This was especially visible when doing fractional scaling, e.g. 125%. Thus we need to get the fraction of the actual on-screen position instead. This has to be done both when populating the cache for the Qt Quick case (this enabler adds it as opt-in) and also when actually selecting the correct rendering of the glyph (change in Qt Declarative).

* Implement vertical subpixel positioning where availableEskil Abrahamsen Blomfeldt2021-01-251-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some use cases, vertical subpixel positioning may be useful, as it allows you to vertically align text with other painting primitives. This does impose an overhead, so we make it opt-int with a render hint on the painter. Note that this is only supported on Freetype currently. It might be possible to support on older macOS versions, prior to Mojave (which has disabled subpixel positioning entirely), but since it would have limited usefulness and Freetype is cross-platform anyway, I skipped that. Note: This drive-by-fixes an issue with subpixel positioning where glyphs would always be offset by 1/64, because we added the aliasing offset *after* we had determined the closest subpixel position. The idea of this, as far as I can understand, is rather to snap to nearest subpixel position upwards, not to add an offset to all glyphs, so it should be added before finding the correct position. It had a subtle visual effect when animating the position. It might be that we could get rid of it entirely, as I haven't been able to reproduce any issues with that, but I have moved it instead, to match what I believe the intention was. [ChangeLog][QtGui][Text] Added render hint flag QPainter::VerticalSubpixelPositioning which will position text at subpixel positions vertically whenever supported. In absence of this, text position will be rounded vertically as before.

| * Support pen color with color fontsEskil Abrahamsen Blomfeldt2019-07-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Color fonts may also contain regular alphabet characters that should be rendered with the current pen. In Qt, however, these characters were drawn into the cache with a default pen color of black. Since all characters in a font is currently backed by the same cache, and it would require a lot of plumbing to get around this, a step in the right direction is to include the current pen color in the cache as long as it is an RGB cache. This means that drawing text with the color font with different pen colors will create different caches. There is no API to select font color on Freetype currently, but this problem has also not been observed there, as the fonts in question, with both regular and color glyphs, are not being detected as color fonts (so the text color will be correct). So Freetype will be left out for now. [ChangeLog][QtGui][Text] Fixed bug where regular text rendered with a color font would always display in black.

* Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.

| | | | | | | | | | | | | | | | | | | The destructor is the first virtual method. By not defining it out-of-line, we provoke multiple copies of vtables, not all of which can be merged by the linker. If the linker fails, RTTI such as dynamic_cast and catch-blocks involving the type will not work. Additionally, QFontEngineGlyphCache was not exported, and therefore also not its vtable, making it impossible for users outside of QtGui to get a unique RTTI for the class.

| * GL2PaintEngine: Prevent fillInPendingGlyphs from breaking gradientsTor Arne Vestbø2014-12-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The glyph cache internally uses the image texture unit when blitting, but doesn't always activate the unit before binding its texture, resulting in sometimes binding the glyph cache texture to the wrong unit. The image texture unit is also the same as the brush texture unit, so any time we fill in pending glyphs we need to re-bind the brush texture, otherwise drawing text with eg. gradients will fail after the new glyphs have been filled. The new hasPendingGlyphs() member function of the glyph cache is an optimization so that we don't need to activate and rebind unless there are glyphs that need to be filled.
