[gdal-dev] Writing Pixel Functions with VRT

[Yves Jacolin (free)]

Hello,

I have some question about writing pixel functions with vrt files. I have a 
netcdf file with two subset named U and V.

How can I process sqrt(U^2 + V^2) using this feature with vrt file?

* do I need to create a C file and build GADL with it?
* do I need to create a C file and locate it close to vrt file?

Thanks,

Y.
