Hi.

I've been working with 12 bit greyscale jpeg images in a project, and I'd gotten some success using the Java Advanced Image I/O package to process these, but it's not completely satisfactory.

I did a bit of searching but came up with nothing. I was wondering if there was a plugin for ImageJ that anyone could point me at that can handle these images - so far, when I try opening these with ImageJ, I get the following exception:

sun.awt.image.ImageFormatException: Unsupported JPEG data precision 12
        at sun.awt.image.JPEGImageDecoder.readImage(Native Method)
        at sun.awt.image.JPEGImageDecoder.produceImage(Unknown Source)
        at sun.awt.image.InputStreamImageSource.doFetch(Unknown Source)
        at sun.awt.image.ImageFetcher.fetchloop(Unknown Source)
        at sun.awt.image.ImageFetcher.run(Unknown Source)

Can anyone help me out with this?
