- Question: do you get a message like "QuickTime and a Photo-JPEG codec are
- needed to see this picture", or do you just get a blank image?
-
- If it's the latter, it sounds like the same sort of problem I've hit. The
- QuickTime 1.5 documentation indicates that a change was made to the way
- QuickTime-compressed data is stored in a QuickDraw picture. I assumed from
- my quick skim of the description that the change was done in a backward-
- compatible fashion, but it appears this is not the case.
-
- The result is that compressed pictures created under QuickTime 1.5 are not
- viewable under QuickTime 1.0. It does work the other way, though.
