*********************************** Quick Start ***********************************

Add the following line of code to your Program.cs, or similar file.

private static pdftron.PDFNetloader = pdftron.PDFNetLoader.Instance();

This static initialization must occur before any call to Apryse, so that the correct Apryse library (x86 or x64) will be loaded. This is not required if you are targeting x86 or x64 platforms, but is very helpful if you are targeting AnyCPU platform.

Next, add the following code somewhere that will ensure it will be called before any other calls to Apryse.

pdftron.PDFNet.Initialize();

You are now ready to use Apryse, see the Getting Started Guides below, or head straight to the samples page.

************************************ Important ************************************

The Apryse SDK relies on the Microsoft VC++ Redistributables. These are included when you install Visual Studio, but may not be present on target machines when redistributing your application.
