Re: BatchCrop v1.40 released

Thanks for the update, nice looking program. How do you see Batchcrop working with or in place of ScanTailor, Spreads or Bookscan Wizard?

How do you use Batchcrop in your bookscanning work flow?

Re: New project- looking for a starting point

You will end up with a single fixed camera looking down onto an open book - either then with imaging of the open book, two pages at once or a single page and then rotate book to image other page. The single photograph covering two pages can have keystoning problems, various post-processing programs ...

Re: Book Scanning - What You Can and Cannot Do

I've searched this forum over and under, and can't find a comprehensive list of what we can and cannot do legally with our book scanners. Here in Australia I can take my scanner into an establishment that serves alcohol but cannot purchase an alcoholic beverage for it. I can have alcoholic beverage...

Re: Adjust color automaticly

That is a really unique approach to a single camera inverted scanner! Other people have used the similar roof gable design but with a single stationary camera, aimed at the spine of the open inverted book: http://diybookscanner.org/forum/viewtopic.php?f=1&t=822&p=8150#p8150 http://www.diybookscanner...

As per this thread: http://www.diybookscanner.org/forum/viewtopic.php?f=20&t=2944&p=16906#p16906 I was having what appeared to be an intermittant failure of Homer to run the OCR/tesseract component but not the compression/pdfbeads component. It turns out that file name length was too long. Files see...

Re: Homer glitch with OCR component

Figured it out!! SOrry i bothered to post. I was looking at the tesseract log error and thought - what if the l means length and it wants the file lenght between 3 and 5 digits? And it worked. The 50 page magazine had a 4 digit file number and the larger book I had been trying to do had a six digit....
