They are also certainly not as common as ITU T.81 | ISO/IEC 10918, and (as an example) popular web browsers will not display JPEG 2000 files. The sentence in question was originally referring to proprietary, non-standard formats and was meant to provide historical context. libjpeg was originally released prior to the adoption of JFIF as an official standard, so it encouraged adoption of JFIF as a de facto standard by providing, under a business-friendly free software license, a library for reading and writing images in that format. --- diff --git a/README.ijg b/README.ijg index 948b237..ff2c811 100644 --- a/README.ijg +++ b/README.ijg @@ -269,7 +269,7 @@ a subset thereof, but there are other formats containing the name "JPEG" that are incompatible with the DCT-based JPEG standard or with JFIF (for instance, JPEG 2000 and JPEG XR).
