wpViewPDF

Overview
wpViewPDF allows you to view PDF data that can be loaded from memory, file or stream. wpViewPDF can also open PDF files created by scanner software since it also does CCITT decompression. wpViewPDF includes the component as a .NET and Delphi component and a small example application. The source for the components (C# and Pascal) is included as well. Also an OCX component which works as interface for the wpViewPDF DLL is included. So you can use wpViewPDF in VB or similar. You only have to specify the exact path to the DLL when using the method ViewerStart. This will initialize the component. Since the DLL can be renamed and placed in the directory of your application, "DLL Hell" can be avoided.

One Component for all
It is now possible to not only create PDF files from your application, but also to view them almost instantly. wpViewPDF is the ideal component for this purpose. Although wpViewPDF cannot ensure that you will be able to view all kinds of PDF files, it can display and print PDF files generated with wpCubed's own PDF tools or similar products. At presently a wrapper for both Delphi/C++Builder and .NET are included. If you use the included OCX you can still avoid version conflicts since the "intelligence" is not inside the OCX but inside the DLL. The latter can be loaded from the applications directory.

Drop it in and it is ready to use
The control already includes buttons to change zooming and view modes and even a menu to start printing. Of course, all elements can be switched off.

What's new in WPViewPDF PLUS V2.0?
With the "PLUS" version it is now possible to add text and vector graphics to certain pages of a PDF file (pdf stamping). Any text will be converted to vectors - this allows it to use special fonts. The graphics will be already visible in the viewer before the PDF data has been updated!

A new pdfMerge function exported by the PLUS version makes it possible to use just one DLL call to combine several PDF files to one. The registered PLUS version includes an additional DLL which converts TIFF files (created by scanner software) "on the fly" to PDF data so they can be merged just like PDF files.

PLUS Editon
With the PLUS license you can save the PDF finformation from wpViewPDF which makes it a versatile PDF conversion software. This means you can load in multiple PDF files and save all pages into a new PDF file (=pdf merge, edit pdf).
Certain pages can be marked to be deleted, they will not be displayed by wpViewPDF. When you save the PDF file this pages will be removed. It is also possible to set new security properties (apply, remove encryption) and set property strings int this pdf conversion tool. The wpViewPDF Demo has the PLUS features enabled, but when a new file is created a red cube will be printed on all pages.
