100% Java library for JPEG lossless decoding

问题

I'm searching for a library in 100% Java which could decode JPEG images with jpeg-lossless compression.

I know that ImageIO and JAI already could decode this images, but they're needed a native code which do not exists for all OS.

I would consider open and close source solutions, as ImageIO plugin or stand-alone.

Marco Schmidt wrote a handy "List of Java libraries to read and write pixel image files" a long time ago. It is gone from the web now, but it still possible to view it with the Wayback Machine (as seen in 2009). I don't know if there are any lossless JPEG decoders there, but it might be a good place to start a search.

TwelveMonkeys ImageIO has had support for lossless JPEG for a while.

I think it started out with the same code base as the rii-mango/JPEGLosslessDecoder, but it's main difference/advantage is that it uses the standard ImageIO API.

Basically, this will work:

BufferedImage image = ImageIO.read(new File("my-lossless-jpeg.jpg"));

Disclosure: I'm the main developer/maintainer of the library.

Please have a look at David Clunie great work, this is really the best way!
[Update 09/2017] D. Clunie has updated his codec

This is a stand-alone JPEG codec that implements selective block redaction for use during de-identification. It also supports decompression of lossless JPEG images.

You can try ImageMagick and his open source Java interface JMagick, I've see that it was stable and quick.

Found Grossroots DiCoM that can do what you want. It has bindings for Java. The library is very powerful and it is written in C++. You will have to build it and import the built jar file. I read a jpeg-lossless DICOM file and converted it to BuffredImage using this example.
