I'm looking for a tool which would be able to capture a screen region, pass it to OCR and put the result into clipboard.
import ppm:- | gocr -i - | xclip -selection c" works, but gocr is unreliable: simple text on a webpage has errors. It is a clear font but the OCR tool always misses "r" and replaces it with underscore.
import ppm:- | ocrad -i - | xclip -selection c" says "ocrad: maxval > 255 in ppm "P6" file."
- tesseract needs an image file and does not accept piping input to it.
- xfce4-screenshooter does not do OCR.
- ABBYY Screenshot Reader is proprietary.
- tessnet2 is freeware running on a proprietary platform.
- Google Docs can OCR screenshots in a batch. But my data is confidential and better not put online.
Graphical interface solutions would be acceptable for this question, too.
