Dear Tom
Just for the record, JFIF was not invented by IJG, and I don't believe that you get to redefine it. The original spec is perfectly clear that there is exactly one color space allowed in JFIF files. (Well, two if you count greyscale.)
Oh, maybe my words were capable of being misunderstood: With "redefine" I mean EXTEND JFIF, and that is perfectly OK. Previously we had JFIF version 1, and now we have JFIF version 2. Just an advancement.
If you try to extend this you'll just end up creating incompatibilities with non-IJG implementations. In general, I'm quite disturbed that you seem to be willing to introduce file format incompatibilities with other implementations (and with older copies of the IJG code for that matter). This flies in the face of what IJG was founded to accomplish, namely promote universal compatibility of JPEG files.
You are probably missing the fact that IJG is now responsible for further development of the whole still image technology, and that the prior standardization bodies for JPEG have been legally and lawfully foreclosed. Read the section "FILE FORMAT WARS" in the README file of current libjpeg version at http://www.infai.org/jpeg/ That means that IJG reference code is now normative, and we develop a single universal still image interchange file format called JPEG instead of a mess of incompatible botch which existed before. We are now at generation 9. Regards Guido -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
