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 can 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++ and VB6. To support old VB6 application even further we also included an ActiveX interface into the WPViewPDF package.
Unlike many competing products WPViewPDF displays even large PDF files instantly due to its multithreaded architecture – and without using a cache based on temporary files.
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.
WPViewPDF 4 also introduces a much enhanced form-filling mode. The user can now tab from field to field and the current field is also highlighted. It is possible to change the status of the checkboxes with the space key.
It is also possible to “flatten” PDF files – with this feature the annotations and/or the fields are rendered into the page description.
The user can select text and copy it to the clipboard or make bitmap snapshots. There is an integrated thumbnail and bookmark view.
The new WPViewPDF now also loads many PDFs which have been corrupted.
With Version 4 which has been released in 2016 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)
The PLUS edition of WPViewPDF does everything what the standard edition does but also SAVES PDF documents. It also does some additional “tricks”.
WPViewPDF Version 4 is backwards compatible to version 3 but also implements a new action system. This system makes it possible to initialize the GUI of the viewing application (menu and toolbar) with a few lines of generic code – simply copy our code from the provided examples.
With WPViewPDF you get in a single package
- 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.
