Overview

Additionally OCR every page that looks like a scan.

Pages are graded on raster coverage, whether the text layer is invisible or absent, the image codec, and the producer. Pages at or above min_confidence are OCR'd; the rest keep native text and still go through the Auto quality check.

Detects that a text layer came from a scanner, not whether it is accurate, so a page carrying a good sidecar is OCR'd too.
