[gdal-dev] gdalbuildvrt cannot specify srcnodata for multiple bands

[Jon Morris]

I'm trying to build a vrt and specify multiple source nodata values. It's the same problem with both gdalbuildvrt on the commandline and calling gdal.BuildVRTOptions programmatically. Looking at the doc and at the code, it seems that the srcNodata value needs to be a string of space separated values, e.g. "1 2 3". When I examine the created VRT, the nodata value for each band is 1. It's taken the first value and ignored the other two.

Am I doing this right? I'm still using GDAL 2.2.0, so apologies if this has been fixed in a more recent version.

Thanks,

Jon
