Constructor & Destructor Documentation

◆ QgsInterpolatedLineColor() [1/3]

QgsInterpolatedLineColor::QgsInterpolatedLineColor ( )

Default constructor.

Definition at line 439 of file qgsinterpolatedlinerenderer.cpp.

◆ QgsInterpolatedLineColor() [2/3]

QgsInterpolatedLineColor::QgsInterpolatedLineColor ( const QgsColorRampShader & colorRampShader )

Constructor with variable color depending on magnitude.

Definition at line 445 of file qgsinterpolatedlinerenderer.cpp.

◆ QgsInterpolatedLineColor() [3/3]

QgsInterpolatedLineColor::QgsInterpolatedLineColor ( const QColor & color )

Constructor with fixed color.

Definition at line 450 of file qgsinterpolatedlinerenderer.cpp.

Member Function Documentation

◆ color()

QColor QgsInterpolatedLineColor::color ( double magnitude ) const

Returns the color corresponding to the magnitude.

Definition at line 472 of file qgsinterpolatedlinerenderer.cpp.

◆ coloringMethod()

QgsInterpolatedLineColor::ColoringMethod QgsInterpolatedLineColor::coloringMethod ( ) const

Returns the coloring method used.

Definition at line 492 of file qgsinterpolatedlinerenderer.cpp.

◆ colorRampShader()

QgsColorRampShader QgsInterpolatedLineColor::colorRampShader ( ) const

Returns the color ramp shader.

Definition at line 497 of file qgsinterpolatedlinerenderer.cpp.

◆ graduatedColors()

void QgsInterpolatedLineColor::graduatedColors	(	double	value1,
		double	value2,
		QList< double > &	breakValues,
		QList< QColor > &	breakColors,
		QList< QLinearGradient > &	gradients
	)		const

Returns the break values, graduated colors and the associated gradients between two values.

If the color is fixed or only one color for the interval (value1, value2), returns only one color in breakColors and void lists for breakValues, gradients
If the color ramp is classified with 'exact', returns void gradients
If the color ramp is classified with 'discrete', return gradients with uniform colors
if nothing to render (out of range), return all lists void

Definition at line 528 of file qgsinterpolatedlinerenderer.cpp.
