Basically the numbers are in jump tables after the beginning of the file, but there's a few things in the spec I couldn't figure out. There used to be an XCMD for that in HC days, and I know it's possible... I gave up after a while. Also there's new additions to the spec : EXIF which deals with camera info.
THere are some fixed bytes at the beginning of the file that point to the next header, then another jump, and another until the end of the headers.
Some attempts were based on simple PERL code examples I found on the net, but those didn't work well reliably. There's something missing in the info...
Has anyone written parser in xTalk that will parse a JPEG file and get things like the dimensions, EXIF info, etc.?
Thanks, -- Frank
