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.

geometry()

const QgsAbstractGeometry & QgsGeometryPaintDevice::geometry

(

)

const

Returns the rendered geometry.

metric()

int QgsGeometryPaintDevice::metric ( PaintDeviceMetric  metric ) const

override

Definition at line 640 of file qgsgeometrypaintdevice.cpp.

paintEngine()

QPaintEngine * QgsGeometryPaintDevice::paintEngine ( ) const

override

Definition at line 635 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 629 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.
