**ImageSharp** is a new, fully featured, fully managed, cross-platform, 2D graphics API designed to allow the processing of images without the use of `System.Drawing`.
Built against .Net Standard 1.1 ImageSharp can be used in device, cloud, and embedded/IoT scenarios.
> **ImageSharp** has made excellent progress and contains many great features but is still considered by us to be still in early stages (alpha). As such, we cannot support its use on production environments until the library reaches release candidate status.

> Pre-release downloads are available from the [MyGet package repository](https://www.myget.org/gallery/sixlabors).
**ImageSharp** is a new, fully featured, fully managed, cross-platform, 2D graphics API designed to allow the processing of images without the use of `System.Drawing`. We have been able to develop something much more flexible, easier to code against, and much, much less prone to memory leaks. Gone are system-wide process-locks; ImageSharp images are thread-safe and fully supported in web environments.

### API
Without the constraints of `System.Drawing` We have been able to develop something much more flexible, easier to code against, and much, much less prone to memory leaks.
Gone are system-wide process-locks; ImageSharp images are thread-safe and fully supported in web environments.
Many `Image<TPixel>` methods are also fluent.
Here's an example of the code required to resize an image using the default Bicubic resampler then turn the colors into their grayscale equivalent using the BT709 standard matrix.
`Rgba32` is our default PixelFormat, equivalent to `System.Drawing Color`.
On platforms supporting netstandard 1.3+
```csharp
// Image.Load(string path) is a shortcut for our default type. Other pixel formats use Image.Load<TPixel>(string path))
@ -118,14 +85,29 @@ using (Image<Rgba32> image = new Image<Rgba32>(400, 400))
}
```
For optimized synchronous access within a loop it is recommended that the following methods are used.
`Rgba32` is our default PixelFormat, equivalent to `System.Drawing Color`. For advanced pixel format usage there are multiple [PixelFormat implementations](https://github.com/SixLabors/ImageSharp/tree/master/src/ImageSharp/PixelFormats) available allowing developers to implement their own color models in the same manner as Microsoft XNA Game Studio and MonoGame.
1. `image.GetRowSpan(y)`
2. `image.GetRowSpan(x, y)`
All in all this should allow image processing to be much more accessible to developers which has always been my goal from the start.

### Manual build
If you prefer, you can compile ImageSharp yourself (please do and help!), you'll need:
- [Visual Studio 2017 (or above)](https://www.visualstudio.com/en-us/news/releasenotes/vs2017-relnotes)
- The [.NET Core SDK Installer](https://www.microsoft.com/net/core#windows) - Non VSCode link.
Alternatively on Linux you can use:
- [Visual Studio Code](https://code.visualstudio.com/) with [C# Extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode.csharp)
