.SH DESCRIPTION
\fBpkfillnodata\fR fills nodata values in a raster dataset.
Nodata values are defined as 0 values in the mask raster dataset.
You can use the input file as the mask image if 0 values in the input
raster have to be filled.
Per default, all bands are filled.
Use the option \*(T<\fB\-b\fR\*(T> to fill individual band(s) in a
multiband raster input image.
