Hi all,
I know the IDL dicom package supports dicom files included 12 bit jpeg
compressed data, however I'm wondering if anyone has any tricks for
reading such files without paying the extra $$$ for the dicom
license. Don't want to sound cheap, but I don't quite see the point
of paying for the whole package just to get the ability to read 12 bit
jpegs. If no one has an IDL solution to reading this data, perhaps
someone can point me to an external utility for converting this data?
Thanks in advance for any help you can give.
Ted

Hi,
I am not sure if it would help in your case, but Karsten Rodenacker
has written the code required to use the Bio-Formats image reader from
Loci. I know that Bio-Formats reads Dicom, but I am not so sure about
the 12-bit stuff. It would be worth checking out...
