My code for creating a Tiff raster looks something like this:
int nBands = 5;
dataset->Create(filename, width, height, nBands, ...);
for (int i = 1; i <= nBands; ++i)
GDALRasterBand *band = dataset->GetRasterBand(i);
It appears that only the description to band 1 is written (it's the only
one reported by gdalinfo). A little debugging leads me to believe that
what's happening is that WriteBlock() invokes Crystalize() ->
WriteMetadata(), which takes care of setting the band description. But
once Crystalize() is called, it sets a flag so as to be a NOOP in future
calls. I'm not using streaming.
I'm trying to understand if this behavior is by design, a limitation that I
can't find in the documentation or a bug.
Any pointers appreciated.
