Required a dynamic zoom software for multiple PDF documents
I am working on an application that allows two PDF documents to open in distinct forms. The forms are arranged on top of each other and the top form permits the transparency of the PDF to be arranged so that the user can associate the two documents for the differences. So far I am able to get the basic zoom features to work with both PDF documents, so that their positioning remains same. Is there any dynamic zoom software for multiple PDF documents to make the dynamic zoom and pan features?
