Member Function Documentation

clone()

QgsRandomColorsV2 * QgsRandomColorsV2::clone ( ) const

overridevirtual

Creates a clone of the color ramp.

Implements QgsVectorColorRampV2.

Definition at line 464 of file qgsvectorcolorrampv2.cpp.

color()

QColor QgsRandomColorsV2::color ( double  value ) const

overridevirtual

Returns the color corresponding to a specified value.

Parameters

value

value between [0, 1] inclusive

Returns

color for value

Implements QgsVectorColorRampV2.

Definition at line 407 of file qgsvectorcolorrampv2.cpp.

count()

int QgsRandomColorsV2::count ( ) const

overridevirtual

Returns number of defined colors, or -1 if undefined.

Implements QgsVectorColorRampV2.

Definition at line 396 of file qgsvectorcolorrampv2.cpp.

properties()

QgsStringMap QgsRandomColorsV2::properties ( ) const

overridevirtual

Returns a string map containing all the color ramp's properties.

Implements QgsVectorColorRampV2.

Definition at line 469 of file qgsvectorcolorrampv2.cpp.

setTotalColorCount()

void QgsRandomColorsV2::setTotalColorCount ( const int  colorCount )

virtual

Sets the desired total number of unique colors for the resultant ramp.

Calling this method pregenerates a set of visually distinct colors which are returned by subsequent calls to color().

Parameters

colorCount

number of unique colors

Note

added in QGIS 2.5

Definition at line 427 of file qgsvectorcolorrampv2.cpp.

type()

QString QgsRandomColorsV2::type ( ) const

overridevirtual

Returns a string representing the color ramp type.

Implements QgsVectorColorRampV2.

Definition at line 459 of file qgsvectorcolorrampv2.cpp.

value()

double QgsRandomColorsV2::value ( int  index ) const

overridevirtual

Returns relative value between [0,1] of color at specified index.

Implements QgsVectorColorRampV2.

Definition at line 401 of file qgsvectorcolorrampv2.cpp.
