[GTALUG] Imagemagick and exif data labels question?

[Russell]

Thanks I installed exif tool and was able to insert the comment as I need.

Something funny with the encoding tho.

russ at HECTOR:~/SCRIPTS$ exiftool temp1.jpg |grep Comment
Comment : This is the comment.
Warning : Invalid EXIF text encoding for UserComment
User Comment : FM0 FC111110011:zzzzzz0 7 93
05002d03d42de5183d2 cc0 990 02581c9e 023b1c9e 021e1c4c 02011c2c
01e41c53 01c91b47 02461a36 0

Strings output shows the added text comment is positioned on line two, while the exif cmd has the comment in the middle of output. My kludge is not exactly elegant, but I can get started on annotating the images with imagemagick.

russ at HECTOR:~/SCRIPTS$ strings temp1.jpg |sed "1d"|less|head -1
This is the comment.

Thanks also Scott. I think jhead looks interesting but I can work with exiftool to do what I need for now.

Cheers
