Export Barcode as Stream Example
Once you have created the barcode with the desired value, you can utilize the ToStream method to convert the generated barcode into a MemoryStream, with the default format being PNG image. This functionality also works with the QRCodeWriter, even after applying custom styling.
:path=/static-assets/barcode/content-code-examples/how-to/create-barcode-as-stream-to-stream.csusing IronBarCode;
using System.IO;
// Create one-dimensional barcode
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("IronBarcode1234", BarcodeEncoding.Code128);
// Convert barcode to stream
Stream barcodeStream = barcode.ToStream();
// Create QR code
GeneratedBarcode qrCode = QRCodeWriter.CreateQrCode("IronBarcode1234");
// Convert QR code to stream
Stream qrCodeStream = qrCode.ToStream();IRON VB CONVERTER ERROR developers@ironsoftware.comExport Barcode as Stream in Various Image Formats
There are multiple methods that a user can use to convert the barcode object into a MemoryStream. These methods are for simplicity, in which users can use based on the desired image format stream. Below is the list of available methods:
- BinaryStream property: Returns a System.IO.Stream of the barcode rendered as a Bitmap image.
ToGifStream(): for GIF image format.ToJpegStream(): for JPEG/JPG image format.ToPdfStream(): for PDF document format.ToPngStream(): for PNG image format.ToStream(): for PNG image format as default. Users can however, can input AnyBitmap.ImageFormat enum field as an argument in this method to specify the desired image stream format.ToTiffStream(): for TIFF image format.
Now, let us use the ToJpegStream and ToStream methods to output streams in JPEG image format using the code snippet below:
:path=/static-assets/barcode/content-code-examples/how-to/create-barcode-as-stream-to-jpeg-stream.csusing IronBarCode;
using IronSoftware.Drawing;
using System.IO;
// Create one-dimensional barcode
GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("IronBarcode1234", BarcodeEncoding.Code128);
// Convert barcode to JPEG stream
Stream barcodeStream = barcode.ToStream(AnyBitmap.ImageFormat.Jpeg);
// Create QR code
GeneratedBarcode qrCode = QRCodeWriter.CreateQrCode("IronBarcode1234");
// Convert QR code to JPEG stream
Stream qrCodeStream = qrCode.ToJpegStream();Imports IronBarCode

' Create one-dimensional barcode
Private barcode As GeneratedBarcode = BarcodeWriter.CreateBarcode("IronBarcode1234", BarcodeEncoding.Code128)
' Convert barcode to JPEG stream
Private barcodeStream As Stream = barcode.ToStream(AnyBitmap.ImageFormat.Jpeg)
' Create QR code
Private qrCode As GeneratedBarcode = QRCodeWriter.CreateQrCode("IronBarcode1234")
' Convert QR code to JPEG stream
Private qrCodeStream As Stream = qrCode.ToJpegStream()In summary, IronBarcode makes it incredibly easy and convenient to create and export barcodes to a MemoryStream object, providing a straightforward method for achieving this.
