How does the ASP.NET Core framework handle barcode to image conversion?
Syncfusion Essential® PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can create a barcode and you can convert the barcode to image in the ASP.NET Core platform.
Steps to convert the barcode to image in the ASP.NET Core platform:
- Create a new ASP.NET Core Web Application project.
- Select the Web Application pattern (Model-View-Controller) for the project.
- Install the Syncfusion.Pdf.Imaging.Net.Core NuGet package as a reference to your .NET Core application from nuget.org.
- Add a new button in the Index.cshtml as shown below.
CSHTML
@{Html.BeginForm("CreateDocument", "Home", FormMethod.Get);
{
<div>
<input type="submit" value="Create Document" style="width:150px;height:27px" />
</div>
}
Html.EndForm();
}
- A default controller with a name HomeController.cs is added to the ASP.NET Core project. Include the following namespaces in that HomeController.cs file.
C#
using Syncfusion.Pdf.Barcode; using Syncfusion.Pdf.Graphics;
using Syncfusion.Drawing;
VB.NET
Imports Syncfusion.Pdf.Barcode Imports Syncfusion.Pdf.Graphics
Imports Syncfusion.Drawing
- Add a new action method CreateDocument in the HomeController.cs and include the following code snippet to convert the barcode to image and download it.
C#
//Drawing QR Barcode PdfQRBarcode barcode = new PdfQRBarcode(); //Set an error correction level barcode.ErrorCorrectionLevel = PdfErrorCorrectionLevel.Medium; //Set XDimension barcode.XDimension = 3; //Set text barcode.Text = "http://www.syncfusion.com"; //Convert to image Stream barcodeImage = barcode.ToImage(new SizeF(300,300)); //Download the PDF document in the browser FileStreamResult fileStreamResult = new FileStreamResult(barcodeImage, "application/jpg"); fileStreamResult.FileDownloadName = "Barcode.jpg"; return fileStreamResult;
VB.NET
'Drawing QR Barcode Dim barcode As PdfQRBarcode = New PdfQRBarcode() 'Set an error correction level barcode.ErrorCorrectionLevel = PdfErrorCorrectionLevel.Medium 'Set XDimension barcode.XDimension = 3 'Set text barcode.Text = "http://www.syncfusion.com" 'Convert to image Dim barcodeImage As Stream = barcode.ToImage(New SizeF(300, 300)) 'Download the PDF document in the browser Dim fileStreamResult As FileStreamResult = New FileStreamResult(barcodeImage, "application/jpg") fileStreamResult.FileDownloadName = "Barcode.jpg" Return fileStreamResult
A complete working sample can be downloaded from BarcodeToImage.zip.
By executing the program, you will get the image as follows.
