The Qgis class provides global constants for use throughout the application.
Settings for a color ramp legend node.
Manipulates raster or point cloud pixel values so that they enhanceContrast or clip into a specified ...
Layer tree node points to a map layer.
Feedback object tailored for raster block reading.
Base class for processing filters like renderers, reprojector, resampler etc.
virtual void writeXml(QDomDocument &doc, QDomElement &parentElem) const
Write base class members to xml.
Raster renderer pipe that applies colors to a raster.
virtual int inputBand() const
Returns the input band for the renderer, or -1 if no input band is available.
virtual bool setInputBand(int band)
Attempts to set the input band for the renderer.
virtual QList< int > usesBands() const
Returns a list of band numbers used by the renderer.
virtual QList< QgsLayerTreeModelLegendNode * > createLegendNodes(QgsLayerTreeLayer *nodeLayer)
