With WPViewPDF we provide a powerful component to view and print, and the with the "PLUS" edition also modify PDF files.

With our WPViewPDF you license a powerful tool (for .NET and as VCL for Delphi in one package!) to display and manipulate PDFs right in your application! Since the main PDF engine was compiled into a DLL (32 bit and 64bit are provided) it is also possible to call some DLL functions directly, such as pdfPrint and pdfMerge. This also works from C++.

Unlike many competing products WPViewPDF displays even large PDF files instantly due to its multi threaded architecture - and without using a cache based on temporary files.

This standard edition allows loading and displaying of PDF Files. Please choose the PLUS edition if you need to manipulate PDF files, such as delete pages, add annotations and attachments, i.e x-factur XML data.
