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);
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.
