A cross-platform library for the processing of image files; written in C#

ImageSharp is a new, fully featured, fully managed, cross-platform, 2D graphics API.

Designed to democratize image processing, ImageSharp brings you an incredibly powerful yet beautifully simple API.

Compared to 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.

Built against .Net Standard 1.1 ImageSharp can be used in device, cloud, and embedded/IoT scenarios.
