Randy,

Although "stitching" sounds really simple, it is hardly so.  Many scanners
are not completely linear, because the area near each end of the scan is
distorted a little.  When you attempt to "cut and paste" two segments of a
larger original together, you find that you can never get all of the fine
details to line up at the junction.  A perfect example of this optical
aberration is shown on pages 90-91 of the July 2009 issue of National
Geographic.  A panoramic photo was made up of three images from the same
camera, taken only seconds apart, but there is obvious misalignment between
the edges of each image.

My hat is off to you for intending to scan large pages in one shot.  I think
you'll find that it's a heckuva lot cheaper to pay a graphics shop to scan
large images, than it is to buy (and then learn to use) Adobe Photoshop.  I
do own Photoshop, but I have neither the patience nor the inclination to
spend a lot of time and energy manipulating segments of schematics when I
can get a large page scanned in one pass for less than a dollar.

Subject: [Repeater-Builder] stitching schematics together

  

Thanks Eric!  I will probably do that with my very large pages as you say.
In another group someone mentioned that Adobe Photoshop will stitch together
pdfs so I may try that with some of the 11 x 17s. I wasn’t aware Photoshop
would do graphics like that. 

Thanks again for your reply.

Randy,

Rather than scan large schematics piecemeal, simply take the sheets to a
commercial graphics shop (some Kinko's may have the 11 by 17 equipment) and
have them scan the document in one piece. My local graphics shop can handle
huge schematics, so I take all Motorola and GE fold-out sheets (which are up
to 34 inches wide) and have them scanned directly to PDF and put on a CD or
thumb drive.

Does anyone know or use a program where I can scan large schematics a little
at a time and then connect them back in a file like a pdf file? I can’t
afford a large bed scanner but I have several 11x17s I would like to scan on
my 8 ½ x 11 scanner.
