About WPViewPDF

PDF viewing component for Delphi and .NET.

wpViewPDF allows you to view PDF data that can be loaded from memory, file or stream. wpViewPDF has been developed as a Windows Class which makes it compatible with most Windows based development systems. wpViewPDF can be used to quickly display and print PDF files which were created with wPDF, wPDFControl or wRTF2PDF or with another library. It is directly embedded into your application. It supports ANSI text extraction and text find and highlight functionality.

The PDF (Portable Document Format) has been become extremely important. Today it is expected that an application is not only able to print its output, but also export it directly to PDF.  With WPCubed's tools, based on the wPDF engine many applications nowadays create PDF output.

With WPViewPDF Standard you can also display PDFs in your Delphi and .NET based applications.

WPViewPDF makes it possible to create PDFs as universal print and preview documents which can be stored, sent by e-mail and printed directly with WPViewPDF (or alternatively other PDF readers). Unlike many competing products WPViewPDF can even display large PDF files instantly due to its multithreaded architecture.

WPViewPDF can render most PDF files, it can load several PDF files which are then viewed as one and can add information prior to printing, such as page numbers or labels.

The user can select text and copy it to the clipboard or make bitmap snapshots. There is an integrated thumbnail and bookmark view and with Version 4 it is now also possible to add highlight and frame annotations. With the black-text annotation the selected text will get a black background which makes it impossible to read it after it was printed. (The text is not deleted)

WPViewPDF Version 4 is backwards compatible to version 3 but also implements a new action system which makes it possible to initialize the GUI of the viewing application (menu and toolbar) with a few lines of generic code (simply copy the code provided in the examples).

With WPViewPDF you get:

  • A VCL component for Delphi and C++Builder
  • A .NET control for 64bit and 32bit Windows
  • A DLL which exports some easy to use methods to be used, i.e. in C++
  • A OCX to be used in VB6

WPViewPDF is driven by different interface modules and the central engine DLLs which have been compiled with the latest compilers.

WPViewPDF PLUS
Based on WPViewPDF Standard Edition, the “PLUS” edition can save the PDF information from the viewer. This makes it a powerful PDF manipulation tool and makes it possible to load multiple PDF files and save them -combined- into a new PDF file.
