Description
JPEG 2000 is not well supported by open-source decoders. The following open-source encoders/decoders exist:
Both JasPer and JJ2000 were originally developed as official reference implementations that are part of the JPEG 2000 standard (ISO/IEC 15444-5
). JJ2000 doesn't appear to be under any active development anymore. JasPer is widely used by other open source applications (e.g. see the list on the Jasper Project Home Page, but its development shows very limited activity. Development of OpenJPEG is much more active.
The problem is that, compared to their commercially-developed counterparts, these libraries are relatively slow, lack sufficient stability and don't support all features of the format.
