Extracting text from an image

To extract text from a raster image, use RecognizePage method of AsposeOCR class. This method supports JPEG, PNG, BMP, GIF, and WBMP images.

This method allows you to optionally customize recognition accuracy, performance, and other settings.

Depending on the parameters, the method can either return a string with line breaks, or a RecognitionResult object that allows you to perform advanced manipulations with recognition results: automatically correct spelling, get image regions and save results in various formats.

Read image from path

AsposeOCR api = new AsposeOCR();
String result = RecognizePage("source.png");
System.out.println("Recognition result:\n" + result + "\n\n");

Read image from memory

AsposeOCR api = new AsposeOCR();
BufferedImage source = ImageIO.read(new File("source.png"));
String result = RecognizePage(source);
System.out.println("Recognition result:\n" + result + "\n\n");

Post-process recognition results

AsposeOCR api = new AsposeOCR();
// Customize recognition
RecognitionSettings recognitionSettings = new RecognitionSettings();
recognitionSettings.setLanguage(Language.Ukr);
// Extract text from image
RecognitionResult result = api.RecognizePage("source.png", recognitionSettings);
// Show non-critical recognition problems
result.warnings.forEach((w) -> {
	System.out.println(w);
});
// Get recognition results as JSON
String resultJson = result.GetJson();
