GIMP script to batch split + rotate TIFF images

<< < (2/4) > >>

Ehtyar:
Perhaps if you supplied a sample image we'd be more able to help you with actual command lines.

Ehtyar.

Nod5:
I'm attaching a mockup file that roughly illustrates the format of the input (I used imagemagick to join two tiffs together... so I'm slowly learning something  :D)

ewemoa:
Don't know if the following is of any help, but after looking at:

  http://www.imagemagick.org/Usage/crop/#crop_percent

I tried the following (with success locally) to get at the right-half of an image:

convert inputimage.extension -gravity east -crop 50%x100% outputimage.extension
--- End quote ---

FWIW, I noticed a "Offsets in geometry" section in:

  http://imagemagick.org/script/command-line-processing.php#geometry

and a bit on -gravity at:

  http://imagemagick.org/script/command-line-options.php#gravity

The following page had some pointers to groups of examples:

Nod5:
TIFFRotateSplitMakePDF v090314, http://nod5.dcmembers.com/tiffrotatesplitmakepdf.html
by Nod5, with help from ewemoa

input: multiimage file.tif with two scanned pages per image (= a bookspread, tilted 90 degrees)
what the script does: rotate 90 degrees, split each image in two (L/R page), output file.pdf with all split images in page order

tiffrotatesplitmakepdf.zip contains .exe , .ahk (source) and md5 hashes. made in Autohotkey. requires: http://www.imagemagick.org/


Thank you ewemoa!  :Thmbsup:

ewemoa:
Congratulations!  Glad that it's working for you :)

(Thanks to Ehtyar for bringing up ImageMagick -- it's been years since I've used it -- didn't know there was a Windows port!)
