class QgsRasterLayer : QgsMapLayer, QgsAbstractProfileSource
{
%Docstring(signature="appended")
Represents a raster layer.

A :py:class:`QgsRasterLayer` is instantiated by specifying the name of a
data provider, such as "gdal" or "wms", and a url defining the specific
data set to connect to. The raster layer constructor in turn
instantiates a :py:class:`QgsRasterDataProvider` subclass corresponding
to the provider type, and passes it the url. The data provider connects
to the data source.

Sample usage of the :py:class:`QgsRasterLayer` class:

.. code-block:: python

         my_raster_layer = QgsRasterLayer("/path/to/file.tif", "my layer")
%End

%TypeHeaderCode

This is the constructor for the RasterLayer class.

The main tasks carried out by the constructor are:

- Load the rasters default style (.qml) file if it exists
- Populate the RasterStatsVector with initial values for each band.
- Calculate the layer extents
- Determine whether the layer is gray, paletted or multiband.
- Assign sensible defaults for the red, green, blue and gray bands.
