Selon Julien Michel :
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()
I hop on the thread since I am interested in openjpeg support too. It
seems than those lines you pointed out are quite outdated, because
openjpeg 1.4 released january 2011 provides tile-level reading. Is there
any chance to build the gdal driver with openjpeg 1.4 ?
Many thanks for your help,
Brian,
GDAL's JP2OpenJPEG driver is based on version 2 of OpenJPEG library.

Please read carefully the first lines of http://gdal.org/frmt_jp2openjpeg.html

I am trying to build 1.8.0 on Linux with openjpeg support.
I can easily build and install openjpeg from source
(oropenjpeg_v1_4_sources_r697) into /usr/local
./configure --with-openjpeg
./configure --with-openjpeg=/usr/local
both result in
OpenJPEG support: no
