Always last digit truncated when we print barcode in .NET

Aspose.BarCode Product Family
1

Hi,

We purchased Apose Barcode and PDF . We are using both products in java, we wrote restful services to add barcode images on pdf. one of our .Net applications consuming these restful services …

  1. Rest service accepts .pdf document and barcodeId and returns PDF as byte array with barcode on it.
  2. for the response .net application takes byte stream writes in to file

issue when we see the file its always truncating last digit in the text under the barcode . ( e.g : if barcode is 123456 , its showing as 12345.

Thanks,
Ramesh

@senthil125,

Please share a sample PDF file and the code snippet that you are using for the above described process. This information will help us to reproduce the issue at our end. Furthermore please update us about JDK version at your end.

Attached PDF. JSK Version we are using is : JDK1.8

Code

Document pdfDocument1 = null;
response = new BarcodeAPIResponse();
//Document pdfDocument1 = new Document(“input.pdf”);
// Set coordinates
// Get the page you want to add the image to
// Page page = pdfDocument1.getPages().get_Item(1); // used when actual pdf sending to Document

		InputStream inputFileStream = new ByteArrayInputStream(request.getInputDocument());
		pdfDocument1 = new Document(inputFileStream);
		for( BarcodeMap barcodeMap : request.getBarcodeList() ){
			BarCodeBuilder builder = new BarCodeBuilder();
			builder.setSymbologyType(com.aspose.barcode.Symbology.Code93Extended);
			builder.setCodeText(barcodeMap.getBarcodeId()+"");
			ByteArrayOutputStream outStream = new ByteArrayOutputStream();
			builder.save(outStream, BarCodeImageFormat.Jpeg);
			InputStream is1 = new ByteArrayInputStream(outStream.toByteArray());
			ImageStamp imageStamp = new ImageStamp(is1);
			imageStamp.setXIndent(barcodeMap.getXCoord());
			imageStamp.setYIndent(barcodeMap.getYCoord());
			imageStamp.setHeight(barcodeMap.getHeight());
			imageStamp.setWidth(barcodeMap.getWidth());
			imageStamp.setOpacity(1.0);
			if(barcodeMap.getPageNoInPdf()>0){
				Page page = pdfDocument1.getPages().get_Item(barcodeMap.getPageNoInPdf());
				page.addStamp(imageStamp);
			}else{
				for (int pdfPage = 1; pdfPage <= pdfDocument1.getPages().size(); pdfPage++) {
					Page page = pdfDocument1.getPages().get_Item(pdfPage);
					page.addStamp(imageStamp);
				}
			}
		}
		// Save the new PDF
		ByteArrayOutputStream output = new ByteArrayOutputStream();
		pdfDocument1.save(output);
		pdfDocument1.close();
		// Close image stream
		//is.close();
		response.setStatusCode(BarcodeAPIConstants.WS_RESPONSE_SUCCESS_CODE);
		response.setProcessedForm(output.toByteArray());
		response.setOtherMessage("success");
		return response;
