MagicScaler brings high-performance, high-quality image scaling to .NET.

Windows 7* or later with .NET 4.6 or later

*Windows 7 and Windows Sever 2008 R2 are supported only with the Platform Update installed.

MagicScaler is available on nuget

PM> Install-Package PhotoSauce.MagicScaler

Basic usage looks something like this:

string inPath = @"c:\bigimage.jpg";
var outStream = new MemoryStream(16384);

MagicImageProcessor.ProcessImage(inPath, outStream, new ProcessImageSettings { Width = 400 });

File.WriteAllBytes(@"c:\smallimage.jpg", outStream.ToArray());

See the documentation page for more details.

• Added CubicSmoother preconfigured interpolator.
• Changed Lanczos filter default to 3 lobes. Removed the preconfigured 2-lobe filter and changed the name of Lanczos3 to Lanczos.

Because MagicScaler is still under active development, I am not accepting unsolicited pull requests at this time. If you find a bug or would like to see a new feature implemented, please open a new issue for further discussion. This will hopefully save any wasted or duplicate efforts.
