Extract text and image from a pdf in a selected area or coordinates

I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates.

When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this.

If somebody could help me out in this it would be greatfull. Can you share your ideas and suggestion on how to implement this in .net.

Regards, Arun.M
