TiffDjvuOcr



Overview:

GUI frontend to convert Scan Tailor tiff output to a OCR'ed, searchable djvu file.

 

Screenshots:

 

Supported OS:

Only tested in Windows XP.

by Nod5  -  Free Software GPL3  -  AutoHotkey

Known issues:
Old software, not tested in Windows 10 or with latest version of Tesseract.
The OCR step can in some cases miss a character which makes all subsequent OCR words one character off. That bug needs fixing for this tool to be fit for use again.

How to use:

Drag drop a file on a command.

The first command takes a .tiff as input,
operates on all .tiff in dropfile folder and
outputs an OCR'ed, searchable .djvu file.

- for use on .tiff from Scan Tailor
- operates on *all* .tiff in same folder as dropped file
- uses -lossy setting to minimize djvu file size

 

Dependencies: (try latest windows binary version):
1. DjvuLibre ,  djvu.sourceforge.net
2. Tesseract 3 ,  https://github.com/tesseract-ocr/tesseract
check ReadMe/FAQ on site; two downloads needed:
tesseract-3.00.win32.zip
eng.traineddata.gz (unpack and put in subfolder tesseract-ocr essdata )

 

Command line use:
TiffDjvuOcr.exe "C:.tif"     = all .tif in folder C: to .djvu with OCR
TiffDjvuOcr.exe noocr "C:.tif"  = all .tif in folder C: to .djvu
TiffDjvuOcr.exe "C:.djvu"     = do OCR on a.djvu
TiffDjvuOcr.exe gettif "C:.djvu"    = extract multipage .tif from a.djvu
TiffDjvuOcr.exe img "C:.jpg"    = single image file to .djvu
TiffDjvuOcr.exe join "C:.djvu"     = join all .djvu in C: into one
