Description

The OCROptions.ActiveRecognitionSet property defines what subset of characters (all characters, digits, uppercase letters, lowercase letters and so on) should be used for recognition. Reducing the number of recognizable characters increases the speed and accuracy of the OCR procedure.

To learn more about character recognition, see Using Optical Character Recognition.

JavaScript, JScript

function OCROptionsSample()

  var Rect = Window.Picture();
  Log.Picture(Rect, "Region with the text to be recognized");

  // Creates an OCR object
  var OCRObj = OCR.CreateObject(Rect);
  // Creates an OCROptions object
  var OCROptions = OCRObj.CreateOptions();

  // Modifies the OCR options:
  // Specifies that the only digit will be used for recognition
  OCROptions.ActiveRecognitionSet = 1;

  // Recognizes digits within the text
  // Posts the found digits to the test log
  Log.Message("Found characters:", OCRObj.GetText(OCROptions));

}
