     20'''ST_SetRotation(raster, angle)'''
     21
     22 Set the rotation of the raster. This method actually derive values for pixelsizex, pixelsizey, skewx and skewy based on the provided rotation angle.
     23
     24 '''Open Question:'''
     25  PR: The angle should be provided in radian or in degree?
     26
     27'''ST_Rotation(raster) -> float64'''
     28 Return the georeference's rotation angle in (degree or radiant?) derived from the pixel size and the skew.
     29
     30  PR: I think getting the rotation get no sence since the result of pixelsizes and skew is not necessarily a rotation. It make sence to set it though.

    98118 This function is necessary to optimize ST_Intersection. The raster to be polygonised before proceeding to a vector intersection should first be clipped to the minimal intersecting area using ST_Clip().
