Microsoft.Maui.Graphics

Microsoft.Maui.Graphics is a cross-platform graphics library for iOS, Android, Windows, macOS, Tizen and Linux completely in C#. With this library you can use a common API to target multiple abstractions allowing you to share your drawing code between platforms, or mix and match graphics implentations within a singular application.

Applications

Any dotnet projects needing a multi-platform graphics abstraction that is backed by native APIs can use Microsoft.Maui.Graphics.

.NET MAUI is an example of a project using Microsoft.Maui.Graphics.

Note: Microsoft.Maui.Graphics does not have a MAUI dependency and can be used on any of the supported platforms listed below.

Goals

• No dependencies on System.Drawing
• Support all graphics operations within an abstraction that the underlying abstraction supports.

Status

This is an experimental library; however it's based on code that's been in use in production applications for over 10 years. Because it was refactored out of another code base, some things may have been broken in that process.

Disclaimer

There is no official support. Use at your own Risk.

Supported Platforms

Platform	Supported Abstractions
Xamarin.iOS	CoreGraphics & SkiaSharp
Xamarin.Android	Android.Graphics & SkiaSharp
Xamarin.Mac	CoreGraphics & SkiaSharp
WPF	SharpDX, SkiaSharp, Xaml & GDI
UWP	SharpDX, Win2D, Xaml, SkiaSharp
WinForms	SharpDX, SkiaSharp & GDI
Tizen	SkiaSharp
Linux	SkiaSharp
Xamarin.Forms	Dependent on native platform support (noted above)

Main Abstractions

• Canvas - You can draw to a any of the supported abstractions with a common drawing canvas API and a support of common operations and primitives
  • Rectangle, Point and Color primitives
  • Shapes (Rectangles, Rounded Rectangles, Ellipses, Arcs)
  • Paths
  • Images
  • Fonts
  • Shadows
  • Image and pattern fills
  • Clipping
  • etc...
• Fonts - You can access fonts with a common API
• Attributed text - You can draw attributed text with a common API
• Bitmaps - You can create and draw on bitmap images with a common API
• PDF - You can create PDF's using a common API

Known Limitations

• Attributed text is not currently supported with SkiaSharp
• The included Blazor (Canvas) implementation no longer compiles, but is included as a reminder to get it working again
