Tesseract timeout Functions. I discarded both as unlikely. I was able to fix this, as @FrankStrieter had suggested, by adding the tesseract-timeout. If you want to restrict recognition to a sub-rectangle of the image - call SetRectangle(left, top, width, height) after SetImage. image_to_string() takes too much time when I run the script through supervisordd, but executes almost instantaneously when run directly in shell (on the same server and simultaneously with supervisor scripts). To prevent excessively long OCR jobs consider setting --tesseract-timeout and/or --skip-big arguments. If you want to have single character recognition, set psm = 10. You switched accounts on another tab or window. If you set --tesseract-timeout 0 OCRmyPDF will apply its image processing without performing OCR (by causing OCR to time out).
