Recoll user manual

Recoll main configuration file, recoll.conf

Tell the non-default Python image handler to run OCR. See the PDF section for PDF OCR. The image OCR also needs mimeconf changes. See the manual. imgocr can be defined for subdirectories.

OCR modules to try. The top OCR script will try to load the corresponding modules in order and use the first which reports being capable of performing OCR on the input file. Modules for tesseract (tesseract) and ABBYY FineReader (abbyy) are present in the standard distribution. For compatibility with the previous version, if this is not defined at all, the default value is "tesseract". Use an explicit empty value if needed. The value be redefined in subtrees.

Location for caching OCR data. The default if this is empty or undefined is to store the cached OCR data under $RECOLL_CONFDIR/ocrcache.

Language to assume for tesseract OCR. Important for improving the OCR accuracy. This can also be set through the contents of a file in the currently processed directory. See the rclocrtesseract.py script. Example values: eng, fra... See the tesseract Web sitedocumentation for language codes and how to download additional language packs. When specifying multiple languages, use a '+' separator and no spaces, e.g. eng+fra. The value be redefined in subtrees.

Path for the tesseract command. Do not quote. This is mostly useful on Windows, or for specifying a non-default tesseract command. E.g. on Windows. tesseractcmd = C:/ProgramFiles/Tesseract-OCR/tesseract.exe

Language to assume for abbyy OCR. Important for improving the OCR accuracy. This can also be set through the contents of a file in the currently processed directory. See the rclocrabbyy.py script. Typical values: English, French... See the ABBYY documentation.

Path for the abbyy command The ABBY directory is usually not in the path, so you should set this.
