[Mathieu Malaterre]

Control: tags -1 patch

On wheezy (see attached file):

$ identify white.j2k
white.j2k JPC 1084x2318 1084x2318+0+0 8-bit DirectClass 335B 1.090u 0:01.080
$ dpkg -L libmagickcore5 | grep jp2
/usr/lib/x86_64-linux-gnu/ImageMagick-6.7.7/modules-Q16/coders/jp2.so
/usr/lib/x86_64-linux-gnu/ImageMagick-6.7.7/modules-Q16/coders/jp2.la

On jessie:

$ identify white.j2k
identify: no decode delegate for this image format `J2K' @
error/constitute.c/ReadImage/501.
$ dpkg -L libmagickcore-6.q16-2 | grep jp2
-> empty !


It seems jasper used to be reference JPEG 2000 implementation but
disapear at some point, and was replaced with openjpeg 2.1.x but
debian package was not updated.

Please consider applying this patch (jessie?):

libopenjp2-7-dev is missing from the B-D.

After applying patch:

$ identify white.j2k
white.j2k J2K 1084x2318 1084x2318+0+0 8-bit Grayscale Gray 335B 0.000u 0:00.000
