Base class for processing modules.
Definition: qgsrasterpipe.h:41
This class provides qgis with the ability to render raster datasets onto the mapcanvas.
const QgsMapToPixel * mMapToPixel
Implementation of threaded rendering for raster layers.
Perform transforms between map coordinates and device coordinates.
Definition: qgsmaptopixel.h:34
QgsRasterLayerRenderer(QgsRasterLayer *layer, QgsRenderContext &rendererContext)
QgsRasterViewPort * mRasterViewPort
Contains information about the context of a rendering operation.
Base class for utility classes that encapsulate information necessary for rendering of map layers...
virtual bool render()
Do the rendering (based on data stored in the class)
This class provides details of the viewable area that a raster will be rendered into.
