TIFF Data formats [message #55698]

Dear All,

I have to convert several thousand(!) ENVI files to LZW compressed
GeoTIFF's. ENVI outputs GeoTIFF but does not give access to the batch
routine and does not offer LZW compression. IDL (write_tiff), while
giving me a lot of flexibility with the GeoTIFF tags and the
compression, does offer only byte, unsigned short&long and float.
(Strange enough ENVI can write e.g. signed short and read_tiff ingest
its correctly to IDL.)

Anyone an idea or a workaround? Can I modify the data type tag in a
TIFF file after IDL has written it?

Thanks

Peter
