Class DrawingBackendScene

Namespace

SixLabors.ImageSharp.Drawing.Processing.Backends

Assembly

SixLabors.ImageSharp.Drawing.dll

Base type for a retained backend scene: the lowered, reusable form of a batch of drawing commands produced by CreateScene(Configuration, Rectangle, DrawingCommandBatch, IReadOnlyList<IDisposable>?) and later rendered into a target through RenderScene<TPixel>(Configuration, ICanvasFrame<TPixel>, DrawingBackendScene).

Remarks

A scene captures everything a backend needs to replay the commands, including any resources (such as image-brush sources) that must remain alive until the scene is disposed. Disposing the scene releases backend-specific state through DisposeCore() and then the retained owned resources.

Constructors

DrawingBackendScene(Rectangle, IReadOnlyList<IDisposable>?)

Initializes a new instance of the DrawingBackendScene class.

protected DrawingBackendScene(Rectangle bounds, IReadOnlyList<IDisposable>? ownedResources)

Parameters

bounds Rectangle

The target bounds used to create the scene.

ownedResources IReadOnlyList<IDisposable>

Resources that must stay alive for the retained scene.

Properties

Bounds

Gets the target bounds used to create the scene.

public Rectangle Bounds { get; }

Property Value

Rectangle

Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

DisposeCore()

Disposes backend-specific resources retained by this scene.
