Selon Julien Michel <julien.mic...@cnes.fr>: Julien,
I've just diff'ed openjpeg.h of 1.3 and 1.4 and couldn't see much difference between the 2. What make you believe that 1.4 supports tile access ? The JP2OpenJPEG driver in particularly needs the opj_set_decode_area(), opj_read_tile_header() and opj_decode_tile_data() API that are only found in v2 branch openjpeg.h Best regards, Even > I hop on the thread since I am interested in openjpeg support too.
