MiAZOCR reads the text of PDF documents and saves it as a note on each one.
It needs ocrmypdf; if it is missing, the plugin refuses to start and says how
to install it (for example sudo dnf install ocrmypdf poppler-utils or sudo
apt install ocrmypdf poppler-utils).
Extract the text
- Select one or more PDF documents.
- Right-click and open Documents > Annotation > Extract text (OCR)….
- Pick the Document language, and tick Force OCR to read every page even when the PDF already has a text layer.
The text arrives as a note on each document, see Write notes on documents.
Default language
Repository settings > Settings holds the language the OCR engine assumes.
From a terminal
miaz ocr DOCUMENT… does the same without the window, see Command
line.
