Hi Charles, Using screen captures for OCR usually doesn't work directly. You'll need to increase the resolution, perhaps with ImageMagick or something. Tesseract needs the height of each letter to be a certain amount -- you'll find info in the documentation, but try upsizing from 95 to 200 dpi. You should get better results. Ideal range is 200 -- 300 dpi. It is much better if you make the original image at that resolution. --Sven
