Interface IVectorPortrayalSource

Namespace: EncDotNet.S100.Datasets.Pipelines.Portrayal

Assembly: EncDotNet.S100.Core.dll

Capability implemented by vector dataset processors that can produce a Mapsui-free VectorPortrayalResult — the portrayal-output seam that lets the Mapsui renderer build the dataset's layers without the processor (and therefore the headless-facing Pipelines assembly) taking a dependency on Mapsui.

public interface IVectorPortrayalSource

Remarks

Mirrors the IHeadlessImageRenderer capability pattern: the concrete processors implement this alongside their headless Skia path, and the Mapsui renderer feature-tests with processor is IVectorPortrayalSource.

Methods

BuildVectorPortrayalAsync(RenderContext?, CancellationToken)

Builds an immutable, Mapsui-free snapshot of this dataset's vector portrayal for the supplied render context. Implementations run under the processor's render gate and snapshot all mutable portrayal state (palette, ECDIS display, asset pre-warm) so the result is safe to convert to Mapsui layers off the gate.

Task<VectorPortrayalResult> BuildVectorPortrayalAsync(RenderContext? context = null, CancellationToken cancellationToken = default)

Parameters

context RenderContext: Optional render context (palette, scales, ECDIS, mariner).
cancellationToken CancellationToken: Cancellation token.

Returns
