Provides an abstract base implementation of the ICanvas interface.

generic <typename TState>
 where TState : CanvasStatepublic ref class AbstractCanvas abstract : IDisposable, Microsoft::Maui::Graphics::ICanvas

public abstract class AbstractCanvas<TState> : IDisposable, Microsoft.Maui.Graphics.ICanvas where TState : CanvasState

type AbstractCanvas<'State (requires 'State :> CanvasState)> = class
    interface ICanvas
    interface IDisposable

Public MustInherit Class AbstractCanvas(Of TState)
Implements ICanvas, IDisposable

Type Parameters

TState

The type of state managed by this canvas, which must derive from CanvasState.

Inheritance: Object
AbstractCanvas<TState>

Derived: Microsoft.Maui.Graphics.Skia.SkiaCanvas

Implements: ICanvas IDisposable

Remarks

This class handles state management, coordinate transformation, and common drawing operations, while delegating platform-specific rendering to derived classes.

Constructors

Extension Methods

ClipPath(ICanvas, PathF, WindingMode)
ClipRectangle(ICanvas, Rect)
ClipRectangle(ICanvas, RectF)
DrawArc(ICanvas, Rect, Single, Single, Boolean, Boolean)	Draws the arc. This is a helper method to draw an arc when you have a rectangle already defined for the ellipse bounds.
DrawArc(ICanvas, RectF, Single, Single, Boolean, Boolean)	Draws the arc. This is a helper method to draw an arc when you have a rectangle already defined for the ellipse bounds.
DrawCircle(ICanvas, Point, Double)
DrawCircle(ICanvas, PointF, Single)
DrawCircle(ICanvas, Single, Single, Single)
DrawEllipse(ICanvas, Rect)
DrawEllipse(ICanvas, RectF)
DrawLine(ICanvas, PointF, PointF)	Draws a line between two points.
DrawPath(ICanvas, PathF)
DrawRectangle(ICanvas, Rect)	Draws the outline of a rectangle.
DrawRectangle(ICanvas, RectF)	Draws the outline of a rectangle.
DrawRoundedRectangle(ICanvas, Rect, Double, Double, Double, Double)
DrawRoundedRectangle(ICanvas, Rect, Double)
DrawRoundedRectangle(ICanvas, RectF, Single, Single, Single, Single)
DrawRoundedRectangle(ICanvas, RectF, Single, Single)

FillArc(ICanvas, Rect, Single, Single, Boolean)	Fills the arc. This is a helper method to fill an arc when you have a rectangle already defined for the ellipse bounds.
FillArc(ICanvas, RectF, Single, Single, Boolean)	Fills the arc. This is a helper method to fill an arc when you have a rectangle already defined for the ellipse bounds.
FillArc(ICanvas, Single, Single, Single, Single, Single, Single, Paint, Boolean)	Fills the arc with the specified paint. This is a helper method for when filling an arc with a gradient, so that you don't need to worry about calculating the gradient handle locations based on the rectangle size and ___location.
