The JPEG 2000 specification is a further development on the original JPEG file format. It supports both LOSSY and LOSSLESS compression schemes. It still uses many similar compression concepts including separating the Hue and Brightness to allow for differential compression of Black and White and color data. Many new options have been added including sampling sizes,color spaces, and tiling image information. Tiling allows for quicker access to a small portion of a large image.
The JPEG 2000 specification also includes a image to disk file format as well as information for streaming images. This format has a JP2 extension. We currently support the JP2 file format. We also support the J2C format, although this is not part of the standard. J2C files are simply image stream data written straight to disk without the normal image file headers..
JPEG 2000 also has support for custom color spaces. We do not currently provide support for writing custom color spaces. Our current widely distributed JPEG 2000 implementation is royalty free. If you are interested in a faster implementation based on the Kakadu library and are willing to invest at least 5k in initial licensing as well as paying royalties, please contact firstname.lastname@example.org.
