Maximum bit depth supported by the OpenJPEG implementation of JP3D #9

Hello,

Could some one shed light on the maximum bit depth supported by the
OpenJPEG implementation of JP3D ?

I've been able to successfully compress SHORT and CHAR images.

However INT images (even those with a bpp <= 31) (I've tried 30 and
31) seem to segfault. FLOAT  segfaults as well.

Thanks
