Protected Attributes

DictEntry * DicomDict
 pointer to the underlying Dicom dictionary element

 Corresponds to the real length of the data This length might always be even.
uint32_t ReadLength
 Length to read in the file to obtain data.
bool ImplicitVR
 Even when reading explicit vr files, some elements happen to be implicit. Flag them here since we can't use the entry->vr without breaking the underlying dictionary.
size_t Offset
 Offset from the beginning of file for direct user access.
VRKey VR
 Value Representation (to avoid accessing Dicom Dict every time!).
TagKey Key
 Dicom TagKey. Contains Dicom Group number and Dicom Element number (to avoid accessing Dicom Dict every time !) // JPRx.
int PrintLevel
 Amount of printed details for each Dicom Entries : 0 : stands for the least detail level.
