87 Scanned and Crooked pages - HELP!!!
in [Freeware]

From: JD on 2 Jul 2010 23:07 Hi Experts, I have acquired a copy of a very old book that has been scanned. Many of the pages are very crooked. Is there any such thing as a small program that could align all the pages automatically? TIA

What format is the file in? -- John Corliss BS206. Because of all the Googlespam, I block all posts sent through Google Groups. I also block as many posts from anonymous remailers (for example, usenet4all.se, x-privat.org, dizum.com, tioat.net, frell.theremailer.net) as possible due to forgeries posted through them. No ad, CD, commercial, cripple, demo, nag, share, spy, time-limited, trial or web wares OR warez for me, please. Adobe Flash sucks, DivX rules. "First thing we do, we kill all the advertisers..."

For one page at a time, most half reasonable image editors have a "align horizon" function which could be used. I use gimp and this script works both for horizontals or verticals http://registry.gimp.org/node/22910 For batch processing Imagemagick will rotate a collection of images an arbitrary amount, but it is command line. example convert -rotate -2.65 *.pdf new.jpg will rotate all the pdf's 2.65 degrees anti-clockwise and write to jpg files new-1.jpg , new-2.jpg .... If you need a gui XNviewMP has a batch rotate so probably IrfanView will have similar. Again most image editors have some means of determining an angle and it would be up to you to decide on what value to use. -- rich

Is it a local file and does it have any sub-folders which might contain images that you can process? or Does it link to a web site where the images are stored? More info required. -- rich
