#  PDFiumCore [![NuGet](https://img.shields.io/nuget/v/PDFiumCore.svg?maxAge=60)](https://www.nuget.org/packages/PDFiumCore) [![Action Workflow](https://github.com/Dtronix/PDFiumCore/actions/workflows/dotnet.yml/badge.svg)](https://github.com/Dtronix/PDFiumCore/actions)

PDFiumCore is a .NET Standard 2.1 wrapper for the [PDFium](https://pdfium.googlesource.com/pdfium/) library which includes the [binaries](https://github.com/bblanchon/pdfium-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](https://github.com/bblanchon/pdfium-binaries) repository.

### Usage

The preferred way to use this project is to use the [Nuget Package](https://www.nuget.org/packages/PDFiumCore).  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/libraries`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 respective ``src/PDFiumCore/runtimes`` directories.

 - Copies/Overrides ``src/PDFiumCore/PDFiumCore.cs`` with the newly generated ``PDFiumCore.cs``.

##### PDFiumCoreBindingsGenerator Parameters

PDFiumCoreBindingsGenerator.exe requires the following parameters:

 - [0] Set to either a specific Github API release ID for the `bblanchon/pdfium-binaries` project or `latest`. 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.

 - Investigate ARM builds for inclusion.
