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
