Subject: Add the method int ElementSet::IsVRCoherent( uint16_t group )
X-Git-Url: https://git.creatis.insa-lyon.fr/pubgit/?a=commitdiff_plain;h=75726b8bc3eec583090893444bca78aa3352718e;p=gdcm.git

Add the method int ElementSet::IsVRCoherent( uint16_t group )

To check whether *all* the DataEntries of the group have all
       the same type for VR (ImplicitVR or ExplicitVR)
@param group group number to be checked
@return 1:ImplicitVR 2:ExplicitVR -1:NotCoherent
