//Instantiate Aspose.OCR API SDK
var ocrApi = new OcrApi(config);

//set input file name
var name =  "Sampleocr.bmp";
var storage = null;
var folder = null;

//upload file to aspose cloud storage
storageApi.PutCreate(name, null, null, data_path + name , function(responseMessage) {
	assert.equal(responseMessage.status, 'OK');
	//invoke Aspose.OCR Cloud SDK API to extract text and partsinfo from an image
	ocrApi.GetRecognizeDocument(name, null, null, null, null, null, null, storage, folder, function(responseMessage) {
			assert.equal(responseMessage.status, 'OK');
