[Insight-users] Dicom read-write

[Rashindra Manniesing]

HI Mathieu,

Thank you for your response.

Actually I wanted to write a simple (2D) dicom anonymizer, leaving all 
non-private tags intact.  I think that explicitly changing the value of 
an entry should not affect the values of other entries as a side effect.

Rashindra.
