Perform OCR and save it as PDF/A using C# Code

[Rawad25651452npju]

Hello

I have a bunch of images that I want to OCR and save the result as PDF/A.  I have visual studio installed and adobe acrobat pro installed and active.
using the adobe acrobat, I can OCR the image and save it as PDF/A,  but am not able to do this using C# code.  I added the COM reference to the project but when i execulte :  var isOCR = acrobatApp.MenuItemExecute("ADBE:DocumentRecognizeText");    it returns false.

the same for  var isPDFA = acrobatApp.MenuItemExecute("SaveAsOther:PDF/A");

can you help please?

You're looking for a commercial C# SDK like - https://pspdfkit.com/pdf-library/dotnet/. You can both OCR (with Key Value Pairs as well) and save it as PDF/A compliant in .NET C#.

Acrobat is sandboxed, meaning that operations that may pose a security risk are restricted. Some are restricted to use within a specific context and some are blocked completely.  Some Menu items are restricted to use from a privileged context.  But this is controlled by a whitelist that you can change.
