JPEG Plugin

• Read support for the following JPEG "flavors":
  • All JFIF compliant JPEGs
  • All Exif compliant JPEGs
  • YCbCr JPEGs without JFIF segment (converted to RGB, using embedded ICC profile)
  • CMYK JPEGs (converted to RGB by default or as CMYK, using embedded ICC profile)
  • Adobe YCCK JPEGs (converted to RGB by default or as CMYK, using embedded ICC profile)
  • JPEGs containing ICC profiles with interpretation other than 'Perceptual' or class other than 'Display'
  • JPEGs containing ICC profiles that are incompatible with stream data, corrupted ICC profiles or corrupted ICC_PROFILE segments
  • JPEGs using non-standard color spaces, unsupported by Java 2D
  • JPEGs with APP14/Adobe segments with length other than 14 bytes
  • 8 bit JPEGs with 16 bit DQT segments
  • Issues warnings instead of throwing exceptions in cases of corrupted or non-conformant data where ever the image data can still be read in a reasonable way
• Thumbnail support:
  • JFIF thumbnails (even if stream contains "inconsistent metadata")
  • JFXX thumbnails (JPEG, Indexed and RGB)
  • EXIF thumbnails (JPEG, RGB and YCbCr)
• Metadata support:
  • JPEG metadata in both standard and native formats (even if stream contains "inconsistent metadata")
  • javax_imageio_jpeg_image_1.0 format (currently as native format, may change in the future)
  • Non-conforming combinations of JFIF, Exif and Adobe markers, using "unknown" segments in the "MarkerSequence" tag for the unsupported segments (for javax_imageio_jpeg_image_1.0 format)
• Extended write support:
  • CMYK JPEGs
  • YCCK JPEGs
