QgsPointCloudAttribute::DataType greenType
An RGB renderer for 2d visualisation of point clouds using embedded red, green and blue attributes.
Base class for 2d point cloud renderer prepared data containers.
virtual QColor pointColor(const QgsPointCloudBlock *block, int i, double z)=0
An optimised method of retrieving the color of a point from a point cloud block.
virtual bool prepareBlock(const QgsPointCloudBlock *block)=0
Prepares the renderer for using the specified block.
virtual QSet< QString > usedAttributes() const =0
Returns the set of attributes used by the prepared point cloud renderer.
The class is used as a container of context for various read/write operations on other objects.
