Hi,
Derived Bands of the VRT format seems like a very powerful resource.
From the tutorial (http://www.gdal.org/gdal_vrttut.html) it is clear
that the Pixel Functions themselves have to be written in C, which is
probably anyway best for performance.
I also get the impression that the corresponding VRT files with Derived
Bands can only be used by applications written in C/C++, since the Pixel
Functions are only available inside the scope of such an application
program:
http://gis.stackexchange.com/questions/2940/gdal-pixel-functions-question
Does this mean that Pixel Functions can not be used by command line
utilities (e.g. gdalwarp and gdal_translate) or from Python?
Best regards from Knut-Frode
