Hi Mark,

I have done that, two different images scaled in different ways, but booth in mm:
1000px-Graph-paper.tif - test image calibrated manually using ImageJ
20131106-134636.0-IO.tif - radiograph, converted from DICOM image, calibrated by macro using DICOM header information

Mvh
Gerald R. Torgersen
