Hi,
This is a call for discussion on a new RFC :
RFC 51 RasterIO() improvements : resampling and progress callback
http://trac.osgeo.org/gdal/wiki/rfc51_rasterio_resampling_progress
Below the summary :
"""
This RFC aims at extending the RasterIO() API to allow specifying a resampling

Ah, the text of the RFC wasn't clear enough. Bilinear, cubicspline and lanczos
are *additional* algorithms to the existing ones.

Gaussian blur also has another complexity, since it's output
dimensions depend on the fftconvolve mode (using scipy.signal docs

Mike,
The gaussian resampling is the one already available for gdaladdo, that was
added per
http://trac.osgeo.org/gdal/ticket/2137
and
http://trac.osgeo.org/gdal/changeset/15323
Basically :
- for a downscaling of factor between 1 and 2 (and for upscaling as well), it
will use a 3x3 kernel
- for
