Settings

Recognition Languages - Options to set the default OCR language and ability to download new languages.

  • Primary Language: sets the default OCR language to be used.
  • Enable Secondary Language: (Experimental) Enable this option when working with documents that contain multiple languages to recognize text for a secondary language as well as the default selected language.
  • Download OCR Languages: opens the language download manager.

Image Processing - Settings used when passing the scanned image to the OCR engine to recognize text.

  • DPI Resolution: Sets the resolution of the image to be sent to the OCR engine.

Note: From our testing, a resolution of 300 DPI produces good OCR results for most images. When dealing with scans containing noise, you may try using a lower DPI setting to get rid of the noise and obtain better OCR results.
