We are reading NITF images which occupy the lower 12bits of a 16bit
datatype. These images clearly have ABPP=12 and NBPP=16 set in the
header. However, when I use GetMetadataItem("NBITS"), the string
returned is always 'null'. I have also tried GetMetadataItem("ABPP") -
which also returns 'null'.
Does anyone know how to access this information in the NITF header. Are
there any recorded problems regarding this?
I am using GDAL version 1.7.1 on SLES10 linux.
