Hi,
Without really testing, I guess that those images would work great through
ECW/JP2 driver and binaries. This comment is in lib\native\ecw,jp2_support.txt.
"ECW/JP2 support is realized via native libraries compiled from the ECW SDK 3.3
.
As these have to be compiled for every platform the support is limited to
platforms where the libraries are available.
Currently included in OJ PLUS is support for the following combinations
Linux (32bit/64bit) with Java (32bit/64bit)
MacOSX with Java (32bit)
Windows (XP - 8.1 [32bit/64bit]) with Java (32bit)
NOTE: 64bit Java is currently _not_ supported on MacOSX and Windows."
Generally, ECW/JPEG2000 by a company ER-Mapper/ERDAS/Hexagon, Kakadu by
Kakadusoftware and MrSID/JPEG2000 by Lizardtech are good, non-free drivers.
OpenJPEG is good too in the recent version but the JPEG2000 file must have
suitable creation time settings. Jasper driver is useless, and OpenJPEG can
eat memory if big JPEG2000 is written as one tile.
If you can get the native ECW/JP2 to work in your system you should be happy.

Aihe: Re: [JPP-Devel] jp2 driver
Note that I added Jp2 reader to rasterImageLayer framework.
I tried with it too. The problems are the same and regarding 974, it runs out
of memory (java.lang.OutOfMemoryError: Java heap space)

Hi Michael,
I did the tests on your files and had the same output. OJ uses JAI to read jp2,
eventually gdal if libs are installed into "native" folder.
I've never tried gdal: it might works as QGIS uses it

Hi jumpers,
I've problems with image driver which does not read jp2 files correctly
I put some images here :
https://www.dropbox.com/sh/02kbw1biy6els4c/AADEcYAkuq6XW5czz00ONj1La?dl=0
- Image "test" found on the cloud is read correctly by OpenJUMP0
- Image 44* are read by OpenJUMP but with a very poor resolution (and
without referencing). It is read correctly by QGis
- Image 974* freeze the application (QGis can read it)
What are your experience with jp2 ? Someone to investigate ?
Michaël
