How to Export Barcodes as Streams

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.
