Title: JFIFVersion parameter can't be changed?
Post by: WAZAAAAA on November 06, 2010, 01:37:30 PM
So I wanted to change the JFIFVersion value thing from 1.02 to 1.01 but it doesn't seem to work.
I've tryed the Exiftool direct function, executed the command line -JFIF:JFIFVersion=1.01 with no success... a popup saying "Warning: Sorry, JFIF:JFIFVersion doesn't exist or isn't writable. Nothing to do."
Does it mean that I can't change it? :\

If someone could tell me a working way to edit it...

Thanks in advance.

Yes.  This version number can't be changed using exiftool.  I'm not sure it is valid just to change the version number.  I would guess that the format of the JFIF information changes with version, but without looking up the specifications I can't be sure.

Thanks, I imagined it. However I've managed to change it by deleting the 1.02 img and making a new one, where I imported the source from another pic.

Anyway, thank you a lot both Phil and Bogdan for creating this awesome tool, really, it's undoubtedly the best on its field and I love it.
