We'll have more information when we get a chance to investigate this problem. ImageMagick supports 12-bit, 14-bit, 10-bit, etc. pixel depths we just need to ensure Jasper does.

Have you considered using 16-bit grayscale PNG? The extra 4 bits
are highly compressible in PNG and don't waste much space.
