A rectangle specified with double values.
void setMultiDirectional(bool isMultiDirectional)
Sets whether to render using a multi-directional hillshade algorithm.
This class provides qgis with the ability to render raster datasets onto the mapcanvas.
QgsRasterRenderer * renderer() const
void setBand(int bandNo)
Sets the band used by the renderer.
void setZFactor(double zfactor)
Set the Z scaling factor of the result image.
int band() const
Returns the band used by the renderer.
QgsRasterDataProvider * dataProvider() override
bool multiDirectional() const
Returns true if the renderer is using multi-directional hillshading.
void bandChanged(int band)
This signal is emitted when the currently selected band changes.
A renderer for generating live hillshade models.
QgsSignalBlocker< Object > whileBlocking(Object *object)
Temporarily blocks signals from a QObject while calling a single method from the object.
double altitude() const
Returns the angle of the light source over the raster.
double zFactor() const
Returns the Z scaling factor.
double azimuth() const
Returns the direction of the light over the raster between 0-360.
Raster renderer pipe that applies colors to a raster.
Base class for raster data providers.
