Detailed Description

A paint device which converts everything renderer to a QgsGeometry representation of the rendered shapes.

Since: QGIS 3.38

Definition at line 124 of file qgsgeometrypaintdevice.h.

Constructor & Destructor Documentation

◆ QgsGeometryPaintDevice()

QgsGeometryPaintDevice::QgsGeometryPaintDevice ( bool usePathStroker = false )

Constructor for QgsGeometryPaintDevice.

If usePathStroker is true, rendered paths will be converted using a stroke respecting the QPainter pen configuration.

Member Function Documentation

◆ geometry()

const QgsAbstractGeometry & QgsGeometryPaintDevice::geometry ( ) const

Returns the rendered geometry.

Definition at line 688 of file qgsgeometrypaintdevice.cpp.

◆ metric()

int QgsGeometryPaintDevice::metric ( PaintDeviceMetric metric ) const

override

Definition at line 642 of file qgsgeometrypaintdevice.cpp.

◆ paintEngine()

QPaintEngine * QgsGeometryPaintDevice::paintEngine ( ) const

override

Definition at line 637 of file qgsgeometrypaintdevice.cpp.

◆ painterPathToGeometry()

QgsGeometry QgsGeometryPaintDevice::painterPathToGeometry ( const QPainterPath & path )

static

Converts a painter path to a QgsGeometry.

Since: QGIS 3.38.1

Definition at line 693 of file qgsgeometrypaintdevice.cpp.

◆ setSimplificationTolerance()

void QgsGeometryPaintDevice::setSimplificationTolerance ( double tolerance )

Sets a simplification tolerance (in painter units) to use for on-the-fly simplification of geometries while rendering.

This will result in simpler, generalised paths.

Set tolerance to 0 to disable simplification. (No simplification is the default behavior).

Definition at line 631 of file qgsgeometrypaintdevice.cpp.

◆ setStrokedPathSegments()

void QgsGeometryPaintDevice::setStrokedPathSegments ( int segments )

Sets the number of segments to use when drawing stroked paths with a rounded pen.

The default is 8 segments, a smaller number will result in simpler paths.
