Bug Number	Synopsis
5089981	A lower resolution image decoded from a JPEG2000 image has incorrect image dimensions.
6175702	The Java and codecLib JPEG2000 ImageReader impls behave differently when resolution level is set
6198998	Clicking the "Close" button on the "Support Information" dialog box does not close the window.
6209803	JPEG 2000 lossy: J2KImageWriterCodecLib ignores bit-depth of pixel values

Changes from 1.1-alpha to 1.1-beta

• The JPEG reader supports image metadata in the JPEG native and standard (plug-in neutral) formats.
• The JPEG reader now handles CMYK and YCCK images properly; the writer writes CMYK images with no transform.
• The JPEG, PNG, and TIFF readers automatically use an embedded ICC profile if present unless an alternate compatible image type is specified by the application.
• The PNG and TIFF writers automatically write an embedded ICC profile if the image has an ICC color space which is not one of the standard Java color spaces.
• EXIF support for both the compressed and uncompressed variants has been improved by:
  • Adding to the TIFF writer the ability to write or insert empty images.
  • Modifying the TIFF reader and writer to handle the JPEG-in-TIFF variant used for EXIF thumbnails.
  • Implementing support for the TIFF native image metadata format in the JPEG reader plug-in.
  These changes allow reading and writing uncompressed EXIF-TIFF images and reading and writing EXIF APP1 marker segments in compressed EXIF-JPEG images.
• The TIFFDirectory and TIFFField classes have been moved to the public package com.sun.media.imageio.plugins.tiff to simplify reading and writing TIFF metadata for applications that prefer this approach to manipulating an IIOMetadata object.
