Re: Scan Tailor Advanced

Orpheus2017,

This commit should have fixed your issue. I am not sure if it made it into Scan Tailor Advanced or not. You can try applying it manually and see if it helps.

Re: Scan Tailor "Experimental"

Hi tomse , It's been a while since I worked on Scan Tailor Experimental or any other version of Scan Tailor. There is also no one else who could implement new features. I can only suggest you to make sure you are running the latest version, which you will find at the top of this page . As for 96 DPI...

Re: What geometric distortions selections to use/choose?

First of all, if you have two pages on a single output image, your "Split Pages" settings are wrong. Dewarping is not going to work on two pages at a time. The correct distortion mode for your examples is "Curved Lines". However, your case is too hard for automatic dewarping to handle, so you will n...

Re: Unable to get ScanTailor Output

You run batch processing by clicking the "Play" button. If there were two pages on the photo, you still need to run it.

Re: Unable to get ScanTailor Output

Have you followed the advice of running batch processing on either the "Select Content" or the "Margins" stage? If that still didn't help, please record a screencast, upload it somewhere and post a link here. For recording a screencast, I would recommend the free BB Flashback Express software.

Re: ST just for splitting pages

I am no longer involved in Scan Tailor development, though I can point you to the relevant code. The page splitting algorithm is roughly as follows: Do some pre-processing to suppress stuff other than more or less vertical lines (see filters/page_split/VertLineFinder.cpp) Find such lines in pre-proc...

Re: Should you always enable resolution enhancement?

So there is no need to set output to 600 dpi for Color scans if the input is 300 dpi?
You do benefit quality-wise from doing so. Now, if you went from 600 to 1200, I would say it's not worth it.

Re: Should you always enable resolution enhancement?

There is one more reason to do resolution enhancement that I overlooked initially. That one also applies to B/W output. Consider the chain of transformations applied to your original scans before they end up on the end-user's screen: Original scan -> [lossy transformation] -> E-book -> [lossy transf...

Re: How to get the same good result for this picture using Scan Tailor

The individual TIFF output files are not expected to be small. To produce the smallest possible PDF or DJVU file from them while preserving color pictures, you need to use the Mixed output mode in Scan Tailor and to use some PDF/DJVU encoding software that knows it deals with Scan Tailor Mixed mode ...

Re: How to get the same good result for this picture using Scan Tailor

Can i install the experimental version in another directory so that i won't lose the classic version or there will be conflict between them ? Unfortunately, even if you specify a different installation directory, it still overwrites start menu items. Not a big problem though, as you can then re-ins...
