Methods

GetBoundingBoxCore()

protected RectangleShape GetBoundingBoxCore()

Returns

RectangleShape

GetTileCore()

protected TileView GetTileCore()

Returns

TileView

DrawAsyncCore(OverlayRefreshType, CancellationToken)

protected Task DrawAsyncCore(OverlayRefreshType refreshType, CancellationToken cancellationToken)

Parameters

refreshType OverlayRefreshType

cancellationToken CancellationToken

Returns

Task

DrawWithoutPostingAsyncCore(OverlayRefreshType, CancellationToken)

This method draws the overlay without posting the result to the map, PostAsync needs to be called after it.

protected Task DrawWithoutPostingAsyncCore(OverlayRefreshType refreshType, CancellationToken cancellationToken)

Parameters

refreshType OverlayRefreshType

        This parameter indicates whether the elements of this overlay needs to be refreshed.
        For example, TileOverlay is formed by tiles.
        When panning the map around, the existing tile doesn't need to be redrawn,
        the only thing we need to do is modifying the position of these tiles.
        On another hand, when click to change the style of the overlay,
        we need to redraw the tile images to change the appearance. So we need refresh mode.

cancellationToken CancellationToken

        The cancellation token for this Async method.

Returns

Task
