Finding paragraph bounding boxes

Aspose.OCR allows you to automatically find the coordinates of image regions containing text paragraphs. This can be useful for highlighting detected areas when previewing an image or extracting individual blocks of text.

To get bounding boxes of all paragraphs of the image, use getTextAreas method of AsposeOCR class. Specify AreasType.PARAGRAPHS as the areaType parameter of the method. isDetectAreas parameter of the method is ignored.

This method works for images in the following formats: GIF, PNG, JPEG, BMP, WBMP.

From file

AsposeOCR api = new AsposeOCR();
ArrayList<Rectangle> paragraphs = api.getTextAreas("source.png", AreasType.PARAGRAPHS);
paragraphs.forEach((region) -> {
	System.out.println(region.recognitionText);
});

From memory

AsposeOCR api = new AsposeOCR();
BufferedImage source = ImageIO.read(new File("source.png"));
ArrayList<Rectangle> paragraphs = api.getTextAreas(source, AreasType.PARAGRAPHS);
paragraphs.forEach((region) -> {
	System.out.println(region.recognitionText);
});

Coordinates of each paragraph (top-left corner, width and height) are returned as a list of Rectangle objects.
