Java JPEG2000 Reader

JDeli includes a JPEG2000 Reader to read JPEG2000 images into Java. The JPEG2000 Decoder is written in 100% Java with no dependencies.

Key information:

  • 100% Java solution. No dlls or dependencies on native code
  • Supports Bitlevel, Grayscale, RGB, CMYK and YCCK images
  • Fastest Jpeg2000 Decoder in Java

Quick start:

JDeli can automatically detect the file type and will use the JPEG2000 File Reader

BufferedImage image = JDeli.read(jpeg2000ImageFile);

or

Jpeg2000Decoder decoder = new Jpeg2000Decoder();
BufferedImage image = decoder.read(jpeg2000Data);

See the full Javadoc.

Performance comparisons:

These figures were generated using jmh (as documented on our blog) with a standard set of images (also documented). They should be easy to replicate if you wish to validate, the code is on GitHub.

The higher the number, the better.
