[gdal-dev] raster resize

[Even Rouault]

Selon Giacomo Piva <piva at meeo.it>:

Giacomo,

gdal_translate doesn't do the hard work itself and lets other part of GDAL do
it. To be more precise, the resizing of the raster in the context of
gdal_translate is done through the VRT driver (frmts/vrt/vrtsources.cpp). But if
you want to do it yourself with GDAL API, the best is to use the GDALRasterIO()
function directly by specifying dimensions of output buffer that are different
than the dimensions of the source window (this will do nearest neighbour
resampling).
