We have worked a lot in the past with the JPEG2000 support in Imageio and we found that for large imagey it was not suitable. Therefore we decided to use kakadu. Notice that Imageio include JJ2000 (pure java) as well as a wrapper around Japser (c code). > Can > someone tell me what the status of this geotools module is and why it uses > Kakadu instead of Sun's code? The module is not finished yet, it still needs some work to be completed as well as some extensive testing. You interested in helping out? Beside we could make the code configurabel so that we can use also the pure java JJ2000 implementation, even though that is going be inefficient on large raster data (if my memory serves me right, it does implement the ability to use decomposition levels) Simone. > > By the way, I did have to use Sun's latest 1.2 from source control because > there was a bug fix in there that is not in 1.1 resulting in NPEs. > > ~ David Smiley > MITRE > -- > View this message in context: > http://n2.nabble.com/GeoTIFF-within-JP2-tp3824530p3824530.html > Sent from the geotools-gt2-users mailing list archive at Nabble.com. > > ------------------------------------------------------------------------------ > Come build with us!
