122 <H2> Note on odd length data elements</H2>
124 The Dicom Standard PS 3.5 (Data Structures and Encoding) specifies that
125 the data element values which make up a DICOM data stream must be padded
128 Gdcm will <B>tolerate</B> an incorrectly formed odd length data field while
129 <B>reading</B> (thus not enforcing the standard).
131 But gdcm will allways <B>enforce</B> the standard while <B>writing</B>.
133 <!##############################################>
134 <H2> Note on undefined Value Representations</H2>
136 If gdcm encounters an undefined VR (either because in a private group,
137 or because it corresponds to an undocumented public dictionary entry
138 when in implicit VR) while reading a file, it will set that data
139 element's VR to be UN (unknown).
141 <!##############################################>
142 <H2>Note on retired and private data elements</H2>
144 Certain data elements are no longer supported under the v3.0 of the DICOM
145 standard but persist as retired element. Gdcm will consider those
146 elements as standard data element, except that the tag name will be postfixed
147 with the "(RET)" string.
