    Description

      So far a JPXDecode filter for decoding JPEG2000 images stored as XObjects is not implemented.
      I have implemented a simple decode filter using jai-imageio library from https://jai-imageio.dev.java.net/ (see attachment).
      It is only a first base feature implementation since no changes to image dictionary are respected as well as special color space handling.
      Unfortunately I cannot provide you with a PDF document containing such images since the document where I stumbled upon the missing feature is confidential.
