PDFsharp & MigraDoc Foundation

Hi,


I'm new to pdf editing using .net, I have a pdf document, this is a combination of multiple pdf documents, each pdf has GIS spatial images. So all the individual pdf(having GIS spatial images) are combined into single pdf and I'm given that single pdf. When I open the pdf, I see combination of images forming one map and in order to select each image I Click Tools -> Analysis -> Object data Tool. and then Click on the individual Image then it displays a "Model Tree" with all of its properties. My requirement is to add a new property value in to that for each image available in pdf document. This new property value is nothing but the hyperlink to the original pdf document of that image. Is it possible to add a new property for image using pdfsharp? If so can you please help?

Thanks
Sai
