Example 1 with TextDetection

use of com.amazonaws.services.rekognition.model.TextDetection in project aws-doc-sdk-examples by awsdocs.

the class DetectText method main.

public static void main(String[] args) throws Exception {
    // Change the value of bucket to the S3 bucket that contains your image file.
    // Change the value of photo to your image file name.
    String photo = "inputtext.jpg";

    DetectTextRequest request = new DetectTextRequest().withImage(new Image().withS3Object(new S3Object().withName(photo).withBucket(bucket)));
    try {
        DetectTextResult result = rekognitionClient.detectText(request);
        List<TextDetection> textDetections = result.getTextDetections();
        System.out.println("Detected lines and words for " + photo);

            System.out.println("Type: " + text.getType());
            System.out.println();
        }
    } catch (AmazonRekognitionException e) {
        e.printStackTrace();
