Re: How to convert a book to serchable pdf using open source software
(...) I think that completing metadata may be part of this script, but I have not looked for a solution for that yet. I worked on the script a little bit. The metadata function has been implemented. I need to prepare the ToC text file where also metadata are placed and the script is able to read th...

Re: How to convert a book to serchable pdf using open source software
Thank you dtic for this hint. It is very interesting, albeit I'm not able to implement it directly now. I use iPhone as a camera (I do not even have a Cannon camera) and I do not think there is any software that can send images to my computer directly after they are taken. I thought about sending vi...

Re: How to convert a book to serchable pdf using open source software
(...) As I use CLI tools for significant part of work, there may be bash script written, which will run all commands in sequence instead of me. It seems that my script works. So the workflow looks like this: 1. scanning 2. transfer of images to the computer 3. check whether they are in proper order...

Re: How to convert a book to serchable pdf using open source software
Yes, BookCrop only works well if all pages are at roughly the same position in the photos. One solution is to have some part of the scanner setup that holds the book cover/spine in a fixed position when shooting. Otherwise some other, smarter tool that reliably detects the page edges in the photo i...

Re: Raspberry PI camera?
Maybe resolution of images you load to FineReader is too big? I mean especially images taken by Canon. It needs to be taken into consideration that OCR systems do not like both too low and too big DPI. Usually optimal is 300 DPI as OCR engines are trained to work with images of this resolution. It a...

Re: How to convert a book to serchable pdf using open source software
(...), always interesting to read about what workflow people have. Thanks for your interest and comments. (...) So you only have to press the Down key to step preview every tenth image then? Unfortunately not. It is necessary to scroll down with mouse and click on thumbnails in a column. However th...

Re: How to output exact image dimensions
Stage 4 Page Box disabled Content Box auto. After this you need to check whether Scan Tailor chose properly contents on all pages. If any adjustments are necessary, do them manually. In the right hand bottom corner you have a box in which you may change order of pages. Change from 'natural order' to...

Re: How to output exact image dimensions
I meant rather simple stretching of images to the size you want. 'Squeezing" if there are too big or "distending" if there are too small. As there should be only slight difference in case of your output files, "resize" operation should give sufficient result: no visible geom...

Re: How to output exact image dimensions
Well, the advice is about, how to output images that as exactly of dimensions you want to obtain after processing in Scan Tailor. Ghost Script is to create a template with proper dimensions. You need to add one extra page fitting to the size. As your input pages have desired sizes, the workflow woul...
