[gdal-dev] Gdal nodata Complex value

[Even Rouault]

Shawn,

The nodata value at the band level (GDALRasterBand::GetNoDataValue() / 
SetNoDataValue()) is a real number, so there's no complete solution. Usually 
parts of the application that take into account the real part of complex 
numbers and compare it to the nodata value to determine if the pixel is nodata 
or not.

There's an exception however in the warping code where you can pass a nodata 
value formed of a real and imaginary part. See
