If this parameter is omitted, the OCR engine will assume that the text is written in extended Latin.
Make sure you specify the correct language for the image. If you try to recognize Cyrillic text using
Language.Eng, only the characters that look the same in both languages (for example, с and c) will be correctly recognized. Other characters will be replaced with similar-looking alternatives.
Example
The following code sample demonstrates how to specify the recognition language:
AsposeOCR api = new AsposeOCR();
RecognitionSettings recognitionSettings = new RecognitionSettings();
// Recognize Ukrainian text
recognitionSettings.setLanguage(Language.Ukr);
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
System.out.println("Recognition result:\n" + result.recognitionText + "\n\n");
