2017-01-11Make tiff_read return actual length readNicolas Pena
The return value is used to determine whether TIFFReadFile fails. If we return just the length, libtiff will try reading uninitilized values afterwards, on corrupted files.

2017-01-10Fix m_nb_mct_records calculation in opj_j2k_read_mctNicolas Pena
Now we update m_nb_mct_records only when there was a new mct record, and l_mct_data computations all went through. In previous version, the ++l_tcp->m_nb_mcc_records was in the end, without the if. Notice that this is similar to the analoguous in opj_j2k_read_mcc.
