Interface IRecognitionBlock

public interface IRecognitionBlock

This interface represents a block.

Block is a rectangular region that may contain text, picture or any other data. OCR Engine will recognize whole image and will try to find text blocks by itself, if blocks are not specified by user.

 
 OcrEngine ocr = new OcrEngine();
 ocr.setImage(ImageStream.fromFile("image.tiff"));
 ocr.getLanguages().addLanguage(Language.load("english"));
 IRecognitionBlock pictureBlock = RecognitionBlock.createPictureBlock(0, 0, 100, 200);
 ocr.getConfig().addRecognitionBlock(pictureBlock);
 IRecognitionBlock textBlock = RecognitionBlock.createTextBlock(110, 210, 100, 100);
 ocr.getConfig().addRecognitionBlock(textBlock);
 if (ocr.process()) {
     System.out.println(textBlock.getRecognitionData().getText());
 }
