Hello all,

I use the -deskew option quite frequently to straighten scanned page sin my workflow. Usually a tolerance of 40% works best. A problem occurs when I deskew a bunch of images where a few are mostly images on the page. The -deskew option actually skews them more then they were originally.

If anyone aware of other options I can use to when calling the -deskew option? Maybe letting it know if the deskew value is over a certain amount that it would not deskew?

I like the option related to the -rotate where we can use the "<" or ">" to add a little logic to the command.

Thank you.

Perhaps you could post links to a before and after result that is not what you would like. But I don't think there are any other arguments to be used with -deskew. If you have large rotations, and you are on Linux, Mac or Windows w/Cygwin, you could try my unrotate script at the link below. Run the script from a PHP exec() call.
