Comments
JDK-8274735 is proposed to fix the basics so we don't get exceptions from reading CMYK and it renders as closely as possible to as what is intended. This bug is open to cover a more complete handling including metadata spec updates.

Please re-open if - if fix is in progress or on the plan to fix soon - if this is a P3 (file as P3, not P4)

EVALUATION Should consider for Mustang or Dolphin, since JPEG images with CMYK color spaces seem to be more commonplace these days. Note that there is an existing RFE (4799903) on the JAI IIO Tools JPEGImageReader that includes details that may be useful in applying a fix for the core (JDK) JPEGImageReader. ###@###.### 2004-09-10
