[Qgis-developer] Are there convenience functions to do bilinear or cubic raster sampling?

[Anita Graser]

Hi,
Using the raster layer provider's identify() function, I can get the
raster value at the specified location. Are there any convenience
functions to do bilinear or cubic raster sampling as well? Or does
this have to be done manually in the plugin code?
Thanks and best wishes,
Anita
