Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

Another way to create an outline/set of bookmarks for a DjVu file without FineReader and without needing any intermediate PDF format is manually, per bookmark (easy for a small number of bookmarks): 1) open the DjVu file in STDU Viewer: http://www.stdutility.com/index.html 2) in main pane select tex...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

Sadly my old version 9 of ABBYY FineReader can read but not write DjVu format and I'm too tight to upgrade :| Interesting to see that @5m of the video you open the djvu file with what looks like WinDjView: https://sourceforge.net/projects/windjview - running that program I find in its "Edit" menu a ...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

How time flies... my existing installed version of gImageReader (Windows 7) is v.3.2.3 and going to https://github.com/manisandro/gImageReader/releases I see it's now up to v.3.2.99 (Feb 24 2018) the change list for which includes among other items: "Add support for reading DJVU documents".

Re: How to edit the text layer of a PDF?

I may be sending you on a wild goose chase but this may have some leads: https://github.com/manisandro/gImageReader/ I haven't looked at it for some time but I recall a fairly recent version allowed input image pdf to be output with a text layer instead of ocr-only and (maybe) the recognized text co...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

I just added an update to the DRAFT MUG's GUIDE at https://forum.diybookscanner.org/viewtopic.php?f=19&t=2759 and as a lot actually relates to DjVu format it occurred to me to copy the relevant part here which I now do as follows: As will be seen from that thread, using free tools (MS Windows) one c...

Re: DRAFT MUG's GUIDE: Converting old books to PDF

Well, time passes and 'solvitur ambulando' , one learns by doing... Glancing at this (draft) Guide of mine from back in early 2013 two material factors occur to mind from my experience gained in imaging a couple of decayed old books each year since then: 1) I recant! I recant! "#1. And don't usually...

Re: Heavy Speckling

The specimen tif supplied is b&w 2-colors and although 300dpi, I noticed is either insufficiently defined and/or too over-exposed to capture small typeface print. If possible, the quickest route would seem to be re-scanning in greyscale at a suitable dpi, maybe say, 400, and adjusting the scanner op...
