Member Function Documentation

◆ interpolatedColor()

QgsInterpolatedLineColor QgsInterpolatedLineRenderer::interpolatedColor ( ) const

Returns the stroke color used to render.

Since: QGIS 3.20

Definition at line 41 of file qgsinterpolatedlinerenderer.cpp.

◆ interpolatedLineWidth()

QgsInterpolatedLineWidth QgsInterpolatedLineRenderer::interpolatedLineWidth ( ) const

Returns the stroke width used to render.

Since: QGIS 3.20

Definition at line 31 of file qgsinterpolatedlinerenderer.cpp.

◆ render() [1/2]

void QgsInterpolatedLineRenderer::render	(	double	value1,
		double	value2,
		const QgsPointXY &	point1,
		const QgsPointXY &	point2,
		QgsRenderContext &	context
	)		const

Renders a line in the context between point1 and point2 with color and width that vary depending on value1 and value2.

This method assumes that point1 and point2 are in map units. See renderInDeviceCoordinates() for an equivalent method which renders lines in painter coordinates.

Definition at line 228 of file qgsinterpolatedlinerenderer.cpp.

◆ render() [2/2]

void QgsInterpolatedLineRenderer::render	(	double	valueColor1,
		double	valueColor2,
		double	valueWidth1,
		double	valueWidth2,
		const QgsPointXY &	point1,
		const QgsPointXY &	point2,
		QgsRenderContext &	context
	)		const

Renders a line in the context between point1 and point2 with color that varies depending on valueColor1 and valueColor2 and and width that varies between valueWidth1 and valueWidth2.

This method assumes that point1 and point2 are in map units. See renderInDeviceCoordinates() for an equivalent method which renders lines in painter coordinates.

Since: QGIS 3.20

Definition at line 247 of file qgsinterpolatedlinerenderer.cpp.

◆ renderInDeviceCoordinates()

void QgsInterpolatedLineRenderer::renderInDeviceCoordinates	(	double	valueColor1,
		double	valueColor2,
		double	valueWidth1,
		double	valueWidth2,
		QPointF	point1,
		QPointF	point2,
		QgsRenderContext &	context
	)		const

Renders a line in the context between point1 and point2 in device (painter) coordinates with color that varies depending on valueColor1 and valueColor2 and and width that varies between valueWidth1 and valueWidth2.

Since: QGIS 3.22

Definition at line 56 of file qgsinterpolatedlinerenderer.cpp.

◆ setInterpolatedColor()

void QgsInterpolatedLineRenderer::setInterpolatedColor ( const QgsInterpolatedLineColor & strokeColoring )

Sets the stroke color used to render.

Definition at line 36 of file qgsinterpolatedlinerenderer.cpp.

◆ setInterpolatedWidth()

void QgsInterpolatedLineRenderer::setInterpolatedWidth ( const QgsInterpolatedLineWidth & strokeWidth )

Sets the stroke width used to render.

Definition at line 26 of file qgsinterpolatedlinerenderer.cpp.

◆ setSelected()

void QgsInterpolatedLineRenderer::setSelected ( bool selected )

Sets if the rendering must be done as the element is selected.

Since: QGIS 3.20

Definition at line 267 of file qgsinterpolatedlinerenderer.cpp.

◆ setWidthUnit()

void QgsInterpolatedLineRenderer::setWidthUnit ( Qgis::RenderUnit strokeWidthUnit )

Sets the unit of the stroke width.

Definition at line 46 of file qgsinterpolatedlinerenderer.cpp.

◆ widthUnit()

Qgis::RenderUnit QgsInterpolatedLineRenderer::widthUnit ( ) const

Returns the unit of the stroke width.

Since: QGIS 3.20

Definition at line 51 of file qgsinterpolatedlinerenderer.cpp.
