Hi everyone!

Maybe somebody can help me: I am scanning some X-rays on an Epson scanner using
the Silverfast software. In the header information in the files (Image - Properties in
ImageJ) the unit of length is stored in inches. Here in Norway we use the SI metric
system, so I would like to measure in e.g. cm. I can just change the inch to cm in
the "Unit of length" field, and everything works fine (the pixel size is then changed
to the right metric value). What I would like to do is to set the unit of length automatically
to cm, either in ImageJ or some kind of free batch-converting program.
I have also tried to change the DPI to DPCM in the Silverfast software, but the header was
still in inches.
Thank you for any suggestions.
