I actually asked this question already Extract graphical Elements and its coordinate from PDF but I was supposed to write the project in Java.... unfortunately there is no function for this. Plse see the link. I was wondering if PDFSharp has the feature of extracting the coordinats of the graphical elements such as rectangle or so.
PDFsharp can open and modify PDF files, but it cannot display them and it does not provide access to elements of a page.
Finding the co-ordinates where elements are drawn is not a simple task as transformations may apply to the drawing instructions. I never used iText so I don't know if it can do it. PDFsharp can not.
PDFsharp cannot render PDF files. If it could easily determine the co-ordinates of graphical objects, it could easily render PDF files.
