[gdal-dev] -srcnodata in gdalwarp and gdalbuildvrt

[Richard Greenwood]

I have a question that is probably more "user" than "developer". Is there
different place that I should post my question?

I don't think that I understand -srcnodata. I assume that -srcnodata "0 0
0" on a 3 band image means that all 3 bands have to be 0 to be "no data"
but I think what I'm seeing is that if any to the 3 bands is 0 then that
pixel is considered to be "no data". Am I mis-understanding -srcnodata?

Thanks
