Image Text Extraction from Remote Image URL by REST API in Java Apps

				This technical tip allows developers to extract image text from remote image URL using Saaspose.OCR REST API in their Java applications. Some important steps for performing this task is to build URI to extract text, sign URI, execute signed URI request and get response, Parse and deserialize the JSON to an object and Display the value and type of all the extracted text. 
Sample Code for Extracting Image Text from Remote Image URL
//build URI to extract text
	String strURI = "";
strURI = "http://api.saaspose.com/v1.0/ocr/recognize?url=http://s017.radikal.ru/i406/1202/7b/70183bef7a09.jpg&language=english&useDefaultDictionaries=true";
	//sign URI
	String signedURI = Sign(strURI);
	//execute signed URI request and get response
	InputStream responseStream = ProcessCommand(signedURI, "POST");
	String strJSON = StreamToString(responseStream);
	// Parse and deserialize the JSON to a object.
	OCRResponse ocrResponse = gson.fromJson(strJSON, OCRResponse.class);
// Display the value and type of all the recognized barcodes
for (Part part : ocrResponse.getPartsInfo().getList())
{
System.out.println("Text: " + part.getText());
System.out.println("Font Name: " + part.getFontName());
System.out.println("Font Size: " + part.getFontSize());
System.out.println("Bold: " + part.getBold());
System.out.println("Italic: " + part.getItalic());
System.out.println("Underline: " + part.getUnderline());
}
	//Here is the OCRResponse class
	public class OCRResponse extends BaseResponse 
	{
	private String Text;
		private OCREnvelop PartsInfo;
		public String getText() { return Text; }
		public OCREnvelop getPartsInfo() { return PartsInfo; }
	}
	//Here is the OCREnvelop class
	public class OCREnvelop 
	{
		private List Parts;
		public List getList() { return Parts; }
	}
 	//Here is the Part class
	public class Part 
	{
	public Part() { }
	private String FontName;
	private float FontSize;
	private boolean Bold;
	private boolean Italic;
	private boolean Underline;
	private String Text;
	public String getFontName() { return FontName; }
	public float getFontSize() { return FontSize; }
	public boolean getBold() { return Bold; }
	public boolean getItalic() { return Italic; }
	public boolean getUnderline() { return Underline; }
	public String getText() { return Text; }
	}
