Hi, i'm experiencing some problems with the JPEG-2000 file format and Imagemagick.
First of all i needed to identify a jpf file, i couldn't get this to work after lots of tries, any idea if this is supported? I always got following error:
identify -format "%m" Schutters_1.jpf
error: cannot decode code stream
identify: unable to decode image file `Schutters_1.jpf' @ jp2.c/ReadJP2Image/403.
Because the jpf didn't work i wanted to find out why, that's why i started testing .jp2 files. These files do work when i execute them as root, but when i do this as another user, or the www-user (for a php project) it doesn't work (while identifying a jpeg or png does work). I get following error:
identify -format "%m" /tmp/seq-1.jp2
error: cannot decode code stream
identify: unable to decode image file `/tmp/seq-1.jp2' @ error/jp2.c/ReadJP2Image/400.
I think it's using some external plugin or something on which i don't have enough permissions, but i don't know which one.
Does anyone have any experience with these kinds of files?
These are the files:
