Images and barcodes can be merged in the same way like merge fields in a reporting template. An image or barcode placeholder is added at design-time to the template and merged with data from the Json datasource.
You define the type, barcode text length, size and position in your template at design-time in order to merge data dynamically.
This demo uses the MailMerge class and the MVC version of TXTextControl.Web.DocumentViewer included TX Text Control .NET Server for ASP.NET.
