A rectangle specified with double values.
Definition: qgsrectangle.h:35
This class provides qgis with the ability to render raster datasets onto the mapcanvas.
virtual QString min(int index=0)
virtual int selectedBand(int index=0)
static QgsRasterRendererWidget * create(QgsRasterLayer *layer, const QgsRectangle &theExtent)
Renderer for multiband images with the color components.
virtual void setMin(QString value, int index=0)
Manipulates raster pixel values so that they enhanceContrast or clip into a specified numerical range...
virtual QString max(int index=0)
virtual QgsRasterRenderer * renderer()=0
Raster renderer pipe that applies colors to a raster.
virtual void setMax(QString value, int index=0)
Base class for raster data providers.
