Member Function Documentation

double QgsGradientFillSymbolLayerV2::angle ( void  ) const
inline

Reimplemented from QgsFillSymbolLayerV2.

QgsSymbolLayerV2 * QgsGradientFillSymbolLayerV2::clone ( ) const
virtual

Implements QgsSymbolLayerV2.

QColor QgsGradientFillSymbolLayerV2::color2 ( ) const
inline

Color for endpoint of gradient, only used if the gradient color type is set to SimpleTwoColor.

QgsVectorColorRampV2* QgsGradientFillSymbolLayerV2::colorRamp ( )
inline

Color ramp used for the gradient fill, only used if the gradient color type is set to ColorRamp.

GradientCoordinateMode QgsGradientFillSymbolLayerV2::coordinateMode ( ) const
inline

Coordinate mode for gradient.

Controls how the gradient stops are positioned.

QgsSymbolLayerV2 * QgsGradientFillSymbolLayerV2::create ( const QgsStringMap properties = QgsStringMap())
static
double QgsGradientFillSymbolLayerV2::estimateMaxBleed ( ) const
virtual

Returns the estimated maximum distance which the layer style will bleed outside the drawn shape.

Eg, polygons drawn with an outline will draw half the width of the outline outside of the polygon. This amount is estimated, since it may be affected by data defined symbology rules.

Reimplemented from QgsSymbolLayerV2.

GradientColorType QgsGradientFillSymbolLayerV2::gradientColorType ( ) const
inline

Gradient color mode, controls how gradient color stops are created.

GradientSpread QgsGradientFillSymbolLayerV2::gradientSpread ( ) const
inline

Gradient spread mode.

Controls how the gradient behaves outside of the predefined stops
