Thank to Andrew Finkenstadt for hosting the ijg.org site.
Last but not least special thank to Thomas G. Lane for the original
design and development of this singular software package.
FILE FORMAT WARS
The ISO JPEG standards committee actually promotes different
formats like “JPEG 2000” or “JPEG XR” which are incompatible
with original DCT-based JPEG and which are based on faulty
technologies. IJG therefore does not and will not support such
momentary mistakes (see
).
We have little or no sympathy for the promotion of these formats.
Indeed, one of the original reasons for developing this free
software was to help force convergence on common, interoperable
format standards for JPEG files.
Don’t use an incompatible file format!
(In any case, our decoder will remain capable of reading existing
JPEG image files indefinitely.)
TO DO
Version 8 is the first release of a new generation JPEG standard to
overcome the limitations of the original JPEG specification.
More features are being prepared for coming releases...
Please send bug reports, offers of help, etc. to [email protected].
