Kakadu *can* be fast, depends on how you compress your jp2 images :-) (but you know that already :-) ). My experience with GDAL Kakadu driver is that, it is fast but not as fast as I would expect it to be. Daniele and I have developed an imageio plugin which directly uses kakadu JNI withouth using gdal. Unfortunately it was not meant to be used, however we are playing right now with jp2 boxes to expose the geojp2 box in order to parse georeferencing in it. Unfortunately we are not targeting gmlinjpeg2000 in the immediate future. However help and/or additional funding would change this :-). > > Unfortunately it is impossible for me to test ImageIO-EXT GDAL even if the > instructions are fine. I am mostly tied to use ready made binaries. We can't ship binaries for ECW and/or kakadu but we can help people make the binaries. Whoever interested in testing ecw and/or kakadu can contact us directly. > But if > you are going to make speed tests at your house some day I could send you > the Kakadu creation options we are using for JPEG2000 compression. That would be nice. Part of the work on the gdal kakadu driver was to allow more creation options! Most of this were not available on gdal 1.4.4 but it seems that on gdal 1.5 they have been ported. We will move to it after release 1.0 for imageio-ext and at that point we'll check the differences. If you are interested we have a nice internal document describing all the options available. > Options > yield lossless JPEG2000 images which are rather well optimized for > interactive browsing both locally and remotely through JPIP server.
