Can you help?
Thank you very much for considering Aspose.
I would like to share with you that Aspose.Pdf.Kit is an API which can be used with .NET or Java to manipulate PDF files; I’m afraid, it is not a visual editor to edit the files manually. If you want to do the tasks manually then I’m sorry we do not offer any such tool and we’re unable to recommend one. However, I would suggest that you try some editor like Acrobat or LiveCycle Designer or some other tool to add an image control. If you later want to insert the signature image using .NET or Java language then you may try Aspose.Pdf.Kit.
If you find any further questions, please do let us know.
