Hi, Luca

We never listed up all the machines (constructor, model, software 
version, ...) gdcm works with.
Actually, it wouldn't make a lot of sense : *all* the images are 
'gdcm readable'.
(except, for the moment, JPEG2000 -Mathieu is working hard on it-; 
it's not a constructor related pb, but a 'transfert syntax' pb)
I mean : gdcm analyses the 'header', gets all the 'dicom elements', 
and the user may ask to bring the pixels in memory.

It works whatever the processor endianess is, whatever the 'pixel 
size', the pixel sign, the planar configuration, the photometric 
interpretation, the samples per pixel, the transfert syntax.

(when a bug is reported, we fix it within a few days : e.g. gdcm 
1.1.0 didn't work for LUT with 2^16 entries, because we never had 
data to check the code before. Current cvs gdcm version deals with 
them)

To access a single information, like 'Patient name', or 'Institution 
adress', or
'Exposure Time', or 'Slice Thickness', or anything else, you have to 
know it's 'Group number' and 'Element number'.
Just run 'PrintFile filein=yourFileName' to know what your current 
file actually contents.
