* Painting: fix overriding and combining different clip typesEirik Aavitsland2022-03-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | In a recent improvement (6de36918c03e91933fbfb5bf7b53abbe03edf460) the last set clip region or path was stored in separate variables, in order to be set again if the aliasing mode changed. That solution was too simplistic, as it would break down as soon as more than one clip area was set, with the latter either replacing or intersecting the first. It was also unnecessary to introduce new storing of clip areas and transforms, as those are already recorded in the clipInfo stack in the painter state. This patch hence reverts much of that implementation. However the basic idea of setting the clip area again after AA change is good, so that part is kept, implementated instead by calling a pre-existing function to replay the clipInfo stack. One of the baseline test cases is extended to excercise the combination of clip areas. As a driveby, support for setClipRectF is added to the painting baseline test scripts, and the build of the manual lance tool is fixed.

* Don't replace IntersectClip with ReplaceClip on a QPictureChunLin Wang2022-02-101-2/+3
| | | | | | | | | | QPainter should not try to be smart and optimize IntersectClip with ReplaceClip when working on a QPicture paint device. Doing so will change the end result as the actually state when replayed might be different from the one it was recorded in. QPainter will no longer try to replace IntersectClip with ReplaceClip if the paint engine is a QPicture.Consistent with QPainter::setClipRect and QPainter::setClipRegion.

* Update clipping area when antialiasing changesChen Bin2021-10-271-0/+2
| | | | | | | | | | | | | | | | | | | Antialiasing is disabled when the painter's antialiasing attribute is set behind the clipping function(example `setClipPath` or `setClipRegion`). The cause of this problem is that the antialiasing state of the clipping region is not updated after the antialiasing attribute is set. A variable is required to record the painter's transformation state set before the clipping function, because the transformation will be applied to the clipping region, resulting in the abnormal clipping region. The value of `s->matrix` is not accurate for the clipping fun- ction.

| | | | | | | | | | | | | | | | | | Use unique_ptr to indicate ownership. Use std::stack to enforce stack-ness (QStack doesn't). Requires the addition of a clear() function, for which we spin a SmallStack wrapper. It also helps to not have to repeat the value_type... Because we use unique_ptr, `state` and `states` are now exclusive (before, `state` was always `states.back()`). Correspondingly, rename `states` → `savedStates`. As a drive-by, this fixes an off-by-one error in a qWarning() (checked `> 1`, but reported one saved state too many).

* Implement vertical subpixel positioning where availableEskil Abrahamsen Blomfeldt2021-01-251-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make text decorations consistent between ways of drawing textEskil Abrahamsen Blomfeldt2020-02-071-80/+71
| | | | | | | | | | | | | | | | | | | | | | | | | The drawGlyphRun() and drawStaticText() functions would calculate the horizontal origin of the decorations based on the left-most edge of the left-most glyph, in practice including the left bearing of that glyph in the position. But in drawText()/QTextLayout it will always be drawn from the position given as input by the user of the function. The inconsistency was detected in an upgrade of Harfbuzz NG, where the tests on macOS would get a -0.05 left bearing, and as a result the decorations would be painted one pixel to the left in drawGlyphRun()/drawStaticText() compared to QTextLayout. It is not a big deal in practice, but in order to get the Harfbuzz update in, we fix the inconsistency now, by passing the user-input position into the decoration function. This was also an opportunity to consolidate the two code paths, and to unexport the qt_draw_decoration_for_glyphs() symbol, which was exported in Qt 4 only to be usable by Qt Quick 1.

| | | | | | | | | QPixmapCache::find(QString) and QPixmapCache::find(QString, QPixmap&) are deprecated since Qt4 times. Explicit mark them as deprecated so they can be removed with Qt6. Change-Id: Iaf185f69afe02203559a1c812fbb4a95c9049a1d Reviewed-by: Eirik Aavitsland <eirik.aavitsland@qt.io>
* Add support for generating PDFs with losslessly encoded imagesAndre de la Rocha2018-10-251-0/+7
| | | | | | | | | | | | This patch adds the QPainter::LosslessImageRendering flag to QPainter::RenderHints and allows QPdfEngine to recognize it and encode images using a lossless data compression algorithm provided by zlib instead of using lossy JPEG compression, which can produce artifacts with some images.

* Add ObjectMode coordinate mode to QGradientEirik Aavitsland2018-06-221-7/+11
| | | | | | | | | | | | | | | | | | | | | | The ObjectBoundingMode coordinate mode of QGradient allows specifying the gradient coordinates relative to the object being painted. But if the gradient brush also has a transformation, that transformation is applied in the logical, not object, coordinate space. That behavior is counterintuitive. However, changing it now would break existing code. Instead, we introduce a new coordinate mode enum with the expected behavior, and document the old one as deprecated. This prepares to fix the bugs below in qtsvg, by making it possible to specify the same behavior in Qt as SVG has. [ChangeLog][QtGui][QGradient] Add ObjectMode coordinate mode [ChangeLog][Important Behavior Changes] QDataStream version bumped up to 18 to account for changes in the serialization of QGradient.

* Provide presets for QGradientTor Arne Vestbø2018-05-311-0/+31
| | | | | | | | | | | | | Similar to Qt::GlobalColor, the presets allow the user to create brushes based on predefined gradients, quickly getting pretty pixels on screen. The presets are based on the linear gradients from WebGradients, a free collection of gradients, hosted at https://webgradients.com/. The few radial and blended gradient presets have been excluded.
