Detect correct orientation?

[stuporglue]

Hello,

Long time IM user, first time on the forums.

I am scanning several thousand (5-7,000) family photos, and I'm wishing there were a way to detect the correct orientation of the scanned image.

Does IM have any features which would be help me automatically rotate these photos?

Thanks

Are you talking about just landscape vs portrait or arbitrary rotation? Please clarify or provide a link to an example image.

For the first case, though I have never used this and don't know exactly what it does, which may depend upon some information in the meta data, but check out -orient.

For the latter, see -deskew at http://www.imagemagick.org/script/comma ... php#deskew

or if on Linux or Mac or Windows w/cygwin, see my script, unrotate, at the link below.

Especially note that if you are not modifying JPEG photos (only fixing orientation) then jhead may be better!
