Gaussian blur also has another complexity, since it's output

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

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
algorithm

Jukka,
Gdaladdo seems to lose some resampling algorithms.
Ah, the text of the RFC wasn't clear enough. Bilinear, cubicspline and lanczos
are *additional* algorithms to the existing ones.
The damage with
average_mp can't be big by reading the comment from the gdaladdo manual
