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.cs
using 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();

Export 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 simplify the process, allowing users to choose 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 by default. Users can, however, input the 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.cs
using 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
Imports IronSoftware.Drawing
Imports System.IO

' 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.

Frequently Asked Questions

What are the advantages of exporting barcodes as streams using C#?
