SkiaSharp

A cross-platform 2D graphics API for .NET platforms based on Google's Skia Graphics Library. It provides a comprehensive 2D API that can be used across mobile, server and desktop models to render images.

  • SKBitmap can now be encoded directly using Encode
  • SKCanvas can now draw a SKSurface directly
  • SKData can now be created without existing data / uninitialized
  • SKDocument can now create XPS documents (Windows-only)
    • ❗️ There is a known issue with XPS on Windows 10 Mobile: see issue

  • SKPixmap can now also encode the pixel data directly using Encode overloads
  • SKSurface has members to access the pixel data directly
  • ❗️ The emboss SKMaskFilter and shadow SKMaskFilter are no longer available
  • ❗️ SKEncodedFormat and SKImageEncodeFormat are now SKEncodedImageFormat

Code Diff: v1.56.2...v1.57.0

SkiaSharp.Views

A set of pre-prepared UI views, panels and surfaces for drawing. One of these views can be added to the view hierarchy, and then be used for drawing without the need for complex setup. There is also a set of extension methods for converting to/from SkiaSharp and native types.

NuGet: https://www.nuget.org/packages/SkiaSharp.Views/1.57.0

SkiaSharp.Views.Forms

A set of pre-prepared views for Xamarin.Forms, for fully cross-platform drawing code. There are views for both CPU and GPU backends, along with extension methods for converting to/from SkiaSharp and Xamarin.Forms types. Currently available for iOS, Android and UWP.

  • SKCanvasView and SKGLView now correctly resizes in some cases

NuGet: https://www.nuget.org/packages/SkiaSharp.Views.Forms/1.57.0

SkiaSharp.Svg (preview)

Support for SVG has been a hot topic, but Google has stated that this is not going to be a feature coming too soon. However, we do want to support SVG. To this end, we are trying out a lightweight SVG parser.

This goes in part with SKSvgCanvas, which is used to create SVG files. Although both are still "preview" areas because not all the features of SVG have been implemented yet, they are both still very usable for most cases.

NuGet: https://www.nuget.org/packages/SkiaSharp.Svg/1.57.0

SkiaSharp.Extended (preview)

During the process of development and support, we have collected some cool functions that may be useful to some apps. We decided to release these an a package so that everyone can find use for them. This is a very small collection right now, but we hope to extend this with many more features.

We hope you will give them a go and suggest any additional features or utilities that may come in handy. What we have so far is:

  • Initial work for SKGeometry
    • CreateSectorPath will create a pie/donut shape as would be used in a pie/donut chart
    • CreatePiePath will create a pie/donut chart from a series of offset values
    • Various other methods to create regular shape paths

NuGet: https://www.nuget.org/packages/SkiaSharp.Extended/1.57.0-beta

Samples

A few new samples were added to demonstrate some new features.
