* QPageSize: make PageSizeId ctor non-explicitMarc Mutz2021-05-131-1/+1
| | | | | | | | | | | | | | A QPageSize::PageSizeId is a faithful representation of a QPageSize, so the corresponding QPageSize ctor shouldn't be explicit. [ChangeLog][QtGui][QPageSize] Conversion from a QPageSize::PageSizeId is now implicit.

* Avoid processing-intensive painting of high number of tiny dashesEirik Aavitsland2021-04-141-9/+35
| | | | | | | | | | | | | When stroking a dashed path, an unnecessary amount of processing would be spent if there is a huge number of dashes visible, e.g. because of scaling. Since the dashes are too small to be indivdually visible anyway, just replace with a semi-transparent solid line for such cases.

* QPainterPath: fix handling of fill rulesGiuseppe D'Angelo2021-03-262-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | fillRule() contained a major blunder: instead of checking if the d-pointer was allocated, and return a default value if it wasn't, it checked whether the path contained any points. This means that QPainterPath p; p.setFillRule(x); Q_ASSERT(p.fillRule() == x); was failing. As a drive-by to test this change, fix another mistake in clear(): clear is documented to clear the elements in a path, but instead it also changed the fill rule. This commit partially reverses 697910e5fbd382e78bc1bcbac3f5824aded059b4.

* Use design metrics when adding text to QPainterPathEskil Abrahamsen Blomfeldt2021-01-121-0/+5
| | | | | | | | | | | | | | | | | | | | | When we add text to QPainterPath, we will add the design metrics (unhinted glyphs) and scale these down to match the target font size. But the glyph positions we pass in are based on the hinted metrics, samples at the target font size. Thus, on fonts/systems with hinting, these do not match the scaled design metrics outlines. To fix this issue, we make sure the text layout uses design metrics when determining the glyph positions. [ChangeLog][QtGui][Text] Fixed an issue where QPainterPath::addText() would get inconsistent kerning for smaller font sizes when hinting is enabled.

| | | | | | | | | | | | | | | Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with move semantics, its name is misleading. Q_RELOCATABLE_TYPE was introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this patch should have no impact on users.

* Cosmetic stroker: avoid overflows for non-finite coordinatesEirik Aavitsland2020-12-011-0/+2
| | | | | | | | | | | | | | | int overflows are usually avoided by clipping the qreal coordinates to the device rect. However the clip function did not handle inf or nan coordinates, so such values would be passed on.

* QPdf: consolidate usage of uintGiuseppe D'Angelo2020-10-192-3/+4
| | | | | | | | | Objects in QPdf are indexed by uint. In a couple of places (incl. QFontSubset) int were used instead, causing sign conversion warnings (turned into errors by -Werror). Use uint instead. Change-Id: Ie0436c8aff3b67d8ef95a5f26fc16403e7e02bd1 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* QColorSpace: port to QESDPGiuseppe D'Angelo2020-10-184-60/+41
| | | | | | | | | | Replace the hand-rolled refcount management with QESDP. Since the class has a default-constructed / moved-from state where the d-pointer can be nullptr, add a in-class detach() that ensures a private object.
