All,
we are trying to read jpeg2000 tiles with mapserver. We downloaded
jasper-1.900.1.uuid and recompiled gdal 1.6.1 with it. Afterwards we
compiled mapserver 5.0 again. We are now able to read jpeg2000 images
with mapserver but it is extremly slow. A getmap request for a small
image takes more than 20 seconds. Attached you'll find the debug
messages from mapserver. From our perspective, the resampling is
causing the poor performance. We are wondering, why mapserver wants to
resample the tiles. The jpeg2000 tiles all have epsg:25832 and we are
requesting the map in epsg:25832. So do you have any ideas?
Cheers
Holger Porath
