TinyEXR.NET is a C# wrapper of single header-only C++ library tinyexr

tinyexr is a portable single header-only C++ library to load and save OpenEXR (.exr) images

The target framework of TinyEXR.NET is .NET Standard 2.1

WARNING: This library is WIP. API is unstable


TinyEXR.NET can be found on NuGet NuGet (← click it !)

Development build


0. Requirements
  • MSVC that supported C++11 (recommend VS2019 or higher)
  • Powershell (>= 3.0)
  • CMake (>= 3.0.0)
  • .NET SDK x64 (>= .NET Core 3.0)
1. Download the code

First, clone this project or download the latest release and unzip.

2. Build native library

Run build_win-x64.ps1

3. Build TinyEXR.NET

You can use dotnet command in TinyEXR.NET folder: dotnet build --configuration Release

Or, you can open TinyEXR.NET/TinyEXR.NET.sln in VS or any other IDE and compile

4. Finish

Finally, we can find NuGet package in TinyEXR.NET\bin\Release. You can use it anywhere


Although tinyexr provides C interface, the MSVC compiler does not export any symbols by default.

So we have to create a C++ project in the folder native to wrap tinyexr API.

I don't know if there is any better way. But it works. 😃

The reason why we only support x64 platform is that I don't know whether the existing code will work properly if we support x86 or other platforms. Specifically, Is the struct layout at C++ side consistent with C# side? I don't have time to solve this problem at present. So I just give up these platform.

Contribution is welcome!
