Splitt PDF page into 2 equal halfs

[didi1]

Hi experts

I have the following question:

I have a Din A3 scanner and can scan 2 Din A4 pages (scores) in one scan into a Din A3 page format.
Now I want to split this Din A3 Pages again into 2 Din A4 pages.
Do you know any macro for Adobe Acrobat or other program which can do this on PDF files?
Or if I export it on other grahpical format - which software could do so?
Rotating the pages later on with Adobe Acrobat is no problem

Any help appreciated, since this would save me some time.

If you use linux gscan2pdf can do this in automatic and also manually.
When I used Acrobat professional I made 2 scans of the same page and after I crooped each page.
By the way usually scanners have a software that can split a scan in 2 or more pages.I think you have to look for options in your scanner software.

Carmar

thanks for help.

yes my software can allow to define 2 half pages of a A3, but this process is
- first not userfriendly
- and second the scanning the whole A3 page as such and then splitting it
it into 2 A4 would save time.
This is because what ever you define, the scanner goes back to initilal position and start again.
So I'm loosing about 2/5th of my time by unnecessary scanner movements.

With above explaination you understand that making 2 scans of the A3 and then crop them in Adobe Acrobat into 2
A4 would not solve my performance problem.

Are you aware of any Windows utility which could do so (not LINUX).

Thanks four your great help.

and here

you can find a win software that can do that,but to get it you have to mail to the softer writer and pay it.

The simplest way is to use a live cd linux , install gscan2pdf ( if it's not already installed) and you'll get your pages splitted.

If you need help about live cd and gscan2pdf we are here....

With Imagemagick, do

Code: Select all

convert original.tiff -crop 50%x100% newpage.tiff

That will split original.tiff straight down the middle into newpage-0.tiff and newpage-1.tiff.

Try Skan Kromsator (unfortunately, it is in Russian only: http://bolega.hotmail.ru/) or Scan Tailor http://scantailor.sourceforge.net/?q=en/about
or use FineReader - it also has the function of splitting pages - and then save as PDF or TIFF.

I'm trying out ScanTailor right now and it looks like a really slick product. Note that if your scans are always well-aligned when you scan them, then you can batch ImageMagick to do the split very quickly. ScanTailor's split processing seems to work pretty well too, and you can batch that as well.
