Description

Name: moC74494			Date: 06/02/98


sun.awt.image.ImageFormatException:
   Unsupported JPEG data precision 12
at sun.awt.image.JPEGImageDecoder.produceImage()

- many medical images (e.g., CT) are 12-bit.
JPEG allows 12-bit compression, e.g.
Processes 4-5, DCT Transform, Huffman or Arithmetic
Coding, 12 bits accepted
or Processes 14-15 and 28-29, DPCM Transform,
2-16 bits accepted.

EVALUATION I believe Java 2d had JPEG support at one point. I'm assuming it'll go back in once it goes through the public review process. robi.khan@eng 1998-06-02 ========================== Its unclear how much demand there is for this feature. We may or may not address this directly in core, but the Image I/O framework will certainly allow developers to create a codec to support this. We will add this to the list of features to be considered for the Image I/O framework. Closing this as a duplicate of that feature request.
