BeginRender(DisplayList, Bitmap, in Matrix, CancellationToken, IProgress?) Method

Definition

Assembly Broadside.Rendering.dll

Starts drawing list over the current pixels of target, without a background, in time slices: each Continue(TimeSpan) draws until its budget is used.

public ProgressiveRender BeginRender(DisplayList list, Bitmap target, in Matrix deviceTransform, CancellationToken cancellationToken, IProgress<double>? progress)

Parameters

list: DisplayList

The display list.

target: Bitmap

The bitmap; drawing is clipped to it.

deviceTransform: Matrix

The transform from the list's default user space to the bitmap's pixels, as for Render(DisplayList, Bitmap, in Matrix).

cancellationToken: CancellationToken

Cancels the render before its next operation.

progress: IProgress<Double>

Receives the share of the list's operations drawn so far, from 0 to 1 (see BeginReplay(IRenderingBackend, CancellationToken, IProgress<Double>?)), or null.

Returns

ProgressiveRender: The render, with nothing drawn yet. Continue it to the end, or dispose it.

Remarks

Viewer capability 2 (issue #97). Continued to the end, it draws exactly what Render(DisplayList, Bitmap, in Matrix) draws.
