What libraries exist to replace text in a PDF or fill PDF form field? I am looking for something free and cannot use iTextSharp's free version due to the licensing requirement to post my source code.
Live samples for ASP.NET Core, but the libraries are supported on Windows Forms, WPF, Silverlight, ASP.NET and ASP.NET MVC, WinRT, Windows Phone, Windows store universal and Xamarin applications as well.
VB.NET code is provided for all code samples.
A single license for the File Formats Edition costs $995. The whole product is also available for free through the community license if you qualify (less than 1 million USD in revenue).
Note: I work for Syncfusion.
