Clips any GDAL-supported raster file to a given extent. The algorithm is derived from the GDAL grid utility .
Archivo ráster de entrada
Defines a value that should be inserted for the nodata values in the output raster.
Por defecto: None
Extent that should be used for the output raster. Selects only features within the specified bounding box.
Por defecto: 0,1,0,1

processing.runalg('gdalogr:cliprasterbyextent', input, no_data, projwin, extra, output)
Clips any GDAL-supported raster by a vector mask layer. The algorithm is derived from the GDAL grid utility .
Capa ráster de entrada.
Defines a value for the no-data areas of the input raster.
Por defecto: None
Creates an alpha band for the result. The alpha band then includes the transparency values of the pixels.
Predeterminado: False
The resolution of the output raster will not be changed.
Predeterminado: False

processing.runalg('gdalogr:cliprasterbymasklayer', input, mask, no_data, alpha_band, keep_resolution, extra, output)
Extracts contour lines from any GDAL-supported elevation raster. The algorithm is derived from the GDAL contour utility .
Defines the interval between the contour lines in the given units of the elevation raster.
Por defecto: 10.0
Opcional
Defines the attribute name for the field containing the values of the contour lines. If nothing is defines the default name will be ‘ELEV’.
Por defecto: ELEV
