Install

Add the package to your project:

Move from SixLabors.ImageSharp 2.1.x

The public API and the SixLabors.ImageSharp namespace are the same as in SixLabors.ImageSharp 2.1.13. You do not have to change your code.

1. Remove the SixLabors.ImageSharp package reference.
2. Add the PinataLabs.ImageSharp package reference.
3. Build and test your application.

Do not reference both packages in one application. The two assemblies contain the same types, and the compiler cannot select between them (error CS0433).

Target frameworks

The package does not support .NET Framework.

Documentation

Documentation for SixLabors.ImageSharp 2.1.x applies to this package. The source of that version is on the release/2.1.x branch of the Six Labors repository. Later Six Labors versions have a different API, so their documentation does not always apply.

Build from source

You need the .NET 10 SDK and Git LFS. The test images are in Git LFS.

1. On Windows, enable long file paths in Git: git config --system core.longpaths true.
2. Clone the repository: git clone https://github.com/PinataLabs/ImageSharp.
3. Get the test images: git lfs pull.
4. Build the solution: dotnet build ImageSharp.slnx -c Release.
5. Run the tests: dotnet test tests/ImageSharp.Tests -c Release --no-build.

The build treats all warnings as errors.
