Scanning books
Alex Eisenhut:
When scanning books on top of a flatbed all-in-one printer/scanner, you have to flip the book around every other page.
Why don't scanners have a "flip every other page" option when creating a PDF?
Or are there some that do?
The idea that I have to edit the PDF after annoys me.
And are there any scanning apps that are good enough to scan technical stuff with? Like they'll get the grayscale stuff and graphs right?
Benta:
Just change your scanning behaviour :)
Scan the left page, then shift the book so you scan the right page. A general cutting of the format afterwards is easy.
Alex Eisenhut:
I can't, unless the top comes off. It doesn't. It moves up by about an inch, that's it.
David Hess:
I have always scanned to image files and then edited the files before assembling into a PDF. Typically this means editing a couple files to make a set of macros to perform the same steps on all of them, which could include rotating every other file if necessary.
Gyro:
PDFsam Basic has a tool for rotating even or odd pages. In fact it's a great tool for splitting, joining, extracting pages, merging alternate etc.
Best of all, it's open source and free. I've been using it for a while ....
