[gdal-dev] /vsisubfile/ and using MrSID SDK for JPEG2000 in NITF

Folks, I have implemented a new VSI driver allowing subregions of any file to be treated as a file object. The syntax is: /vsisubfile/_, So, for instance, to read a jpeg2000 datastream in a file named /data/abc.ntf with the data stream starting at byte 1000 and being 5000 bytes long you would

[gdal-dev] Write 8-bit image...

Hey Folks, I'm trying to write a perl script to write an 8-bit image. I've been able to modify the "Creating a raster dataset" example using Geo::GDAL ( http://map.hut.fi/doc/Geo-GDAL/html/create_raster.html ) to output float32 and U16 images, but I can't figure out how to output an 8-bit image.
