[jira] Created: (PDFBOX-554) Handle JPEG2000 images via JPXDecode
filter
Handle JPEG2000 images via JPXDecode filter
-------------------------------------------
Key: PDFBOX-554
URL: https://issues.apache.org/jira/browse/PDFBOX-554
Project: PDFBox
Issue Type: Improvement
Components: Parsing
Affects Versions: 1.0.0
Reporter: Timo Boehme
Priority: Minor
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.
