afaik.. the jdk jp2 readers (we only use the newer Imagio one) are very basic and unmaintained.
the ecw one is quite old and native, only for x86. the gdal ones are based on different libraries and should be preferred, albeit being native as well. gdal supports reading JP2 via several libraries http://www.gdal.org/frmt_jpeg2000.html . some of which are contained in the published builds (afair ECW and OpenJPEG, not sure why the free Jasper is missing). the others might be added by providing the necessary libraries. we have gdal builds for OJ from 2014 laying on sf.net https://sourceforge.net/projects/jump-pilot/files/OpenJUMP_plugins/Drivers/ Jukka: i see GDAL 2.00 is out. should we update OJ GDAL support accordingly? the GDAL ECW JP2 driver seems to work with these images of yours. ..ede On 02.10.2016 19:03, Rahkonen Jukka (MML) wrote: > That sounds very promising.
