Obtaining and installing the DLLs

The DLL libcpdf is required. This is free for non-commercial use. Commercial use requires a license. The DLL can be obtained here for all platforms here:

https://github.com/coherentgraphics/cpdflib-binary

Before using the library, you must make sure your project or build environment has access to the cpdf DLL, which is not part of the .NET assembly obtained from NuGet. You can add it to a Visual Studio project as a file, set to copy-to-output-folder. Or, you can install it in a standard location, such as the Windows system folder.

The DLL libcpdf.dll provided in this folder must be renamed to cpdf.dll, for .NET to be able to find it.
