PDFiumCore contains the PDFium library binaries with a .NET Standard 2.1 wrapper containing all the exposed public header methods of the library.

Bindings are generated from the binaries and header files created at pdfium-binaries repository.

• .NET Core 3.1
• .NET Framework 4.8
  • PDFiumCoreBindingsGenerator currently uses CppSharp to read the header files to create the bindings out of. CppSharp currently only has a .NET Framework implementation so to create the PDFiumCore bindings, .NET Framework 4.8 is required. Once a .NET Core version is available, the bindings generator will be updated accordingly.

Build PDFiumCoreBindingsGenerator and edit the file at /bin/Debug/net48/CreatePackage.bat and change the URL to the desired release.

PDFiumCoreBindingsGenerator.exe requires the following parameters:

• [0] Github API url for the release. (eg. https://api.github.com/repos/bblanchon/pdfium-binaries/releases/latest) This is to determine the release version and binary assets to download.
• [1] Version to set the Version.Minor property to. This is used for building patches. Usually set to "0"
• [2] Set to true to download the latest binary assets and extract. False to use the assets if they already exist in the directory.

https://api.github.com/repos/bblanchon/pdfium-binaries/releases/31587582

Execute the CreatePacakge.bat

This will do the following:

• Download the specified files at the passed pdfium-binaries API url.
• Extracts the zip & tgz (Actually tar) files into the current directory.
• Opens the pdfium-windows-x64 directory and parses the header files via CppSharp and generates PDFiumCore.cs in the current directory.
• Copies the libraries and licenses into their respecive src/PDFiumCore/runtimes directories.
• Copies/Overrides src/PDFiumCore/PDFiumCore.cs with the newly generated PDFiumCore.cs.
• Executes dotnet package on the PDFiumCore project. and putputs the Nuget package in the project root output directory.

• Create an actual parser for the comments and generate functional C# method documentation.
• Include documentation for more than just the public methods.
