PDFiumCore 
PDFiumCore is a .NET Standard 2.1 wrapper for the PDFium library which includes the binaries and header pinvoke bindings. Supports Linux-x64, OSX-x64, Win-x64, Win-x86.
Bindings are generated from the binaries and header files created at pdfium-binaries repository.
Usage
The preferred way to use this project is to use the Nuget Package. This will ensure all the proper bindings in the *.deps.json are generated and included for the targeted environments.
Build Requirements
- .NET 6.0
Manual Building
Execute the CreateBindingsPackage.bat
This will do the following:
- Download the specified files at the passed pdfium-binaries API url.
- Extracts the zip & tgz files into the
asset/librariesdirectory. - Opens the pdfium-windows-x64 directory and parses the header files via CppSharp and generates
PDFiumCore.csin the current directory. - Copies the libraries and licenses into their respective
src/PDFiumCore/runtimesdirectories. - Copies/Overrides
src/PDFiumCore/PDFiumCore.cswith the newly generatedPDFiumCore.cs.
PDFiumCoreBindingsGenerator Parameters
PDFiumCoreBindingsGenerator.exe requires the following parameters:
- [0] Set to either a specific Github API release ID for the
bblanchon/pdfium-binariesproject orlatest. This is to determine the release version and binary assets to download. - [1] Set to true to download the libraries and generate the bindings. Set to false to only download the libraries.
- [2] Version to set the Version.Revision property to. This is used for building patches. Usually set to "0"
ToDo
- Create an actual parser for the comments and generate functional C# method documentation.
- Include documentation for more than just the public methods.
