double classificationMin() const
Interface for all raster shaders.
QgsRasterBlock * block(int bandNo, const QgsRectangle &extent, int width, int height, QgsRasterBlockFeedback *feedback=nullptr) override=0
Read block of data using given extent and size.
virtual QList< int > usesBands() const
Returns a list of band numbers used by the renderer.
Abstract base class for color ramps.
QgsRasterShader * shader()
Returns the raster shader.
Type
Supported methods for color interpolation.
double classificationMax() const
Raster renderer pipe for single band pseudocolor.
Base class for processing filters like renderers, reprojector, resampler etc.
const QgsRasterRenderer & operator=(const QgsRasterRenderer &)=delete
QgsRasterRenderer cannot be copied. Use clone() instead.
Uses breaks from color palette.
QgsRasterRenderer * clone() const override=0
Clone itself, create deep copy.
const QgsRasterShader * shader() const
Interpolates the color between two class breaks linearly.
ClassificationMode
Classification modes used to create the color ramp shader.
virtual void legendSymbologyItems(QList< QPair< QString, QColor > > &symbolItems) const
Get symbology items if provided by renderer.
virtual void writeXml(QDomDocument &doc, QDomElement &parentElem) const
Write base class members to xml.
Feedback object tailored for raster block reading.
Raster renderer pipe that applies colors to a raster.
int band() const
Returns the band used by the renderer.
