• offset: Offset into the line type pattern.

RLinetypePatternExporter

RLinetypePatternExporter::RLinetypePatternExporter(RExporter &exporter, const QSharedPointer< RShape > &shape, double offset)

Constructor.

Parameters:

• exporter: Exporter to which the shapes are exported, e.g. a RPainterPathExporter

exportLineSegment

virtual void RLinetypePatternExporter::exportLineSegment(const RLine &line, double angle=RNANDOUBLE)

virtual

Exports the given line segment, mapped to the shapes that are being exported.

Parameters:

• line: Line segment, mapped to the straight, horizontal line starting at 0/0).

virtual inline

Reimplemented from exportPainterPaths.

exportPoint

virtual void RLinetypePatternExporter::exportPoint(const RPoint &)

virtual inline

Exports a point with the current attributes.
