Methods

Name	Description
GetLayerBounds	Gets the geographic bounds (in 0-200, 0-100 viewport units) of the content in this layer. Used for auto-scaling the map to fit content.
Render	Renders this layer to the drawing context.
GetPointData	Gets the data item at the specified screen point. Inherited from MapLayer.
OnPointerExited	Handles pointer exited events. Override this method to handle interactions (e.g. clearing hover effects). Inherited from MapLayer.
OnPointerMoved	Handles pointer moved events. Override this method to handle interactions (e.g. hover effects). Inherited from MapLayer.
OnPointerPressed	Handles pointer pressed events. Override this method to handle interactions (e.g. selection). Inherited from MapLayer.
Bind (8 overloads)	Binds a Avalonia.AvaloniaProperty to an Avalonia.Data.BindingBase. Inherited from AvaloniaObject.
CheckAccess	Returns a value indicating whether the current thread is the UI thread. Inherited from AvaloniaObject.
ClearValue (4 overloads)	Clears a Avalonia.AvaloniaProperty's local value. Inherited from AvaloniaObject.
CoerceValue	Coerces the specified Avalonia.AvaloniaProperty. Inherited from AvaloniaObject.
Equals	Compares two objects using reference equality. Inherited from AvaloniaObject.
GetBaseValue	Inherited from AvaloniaObject.
GetHashCode	Gets the hash code for the object. Inherited from AvaloniaObject.
GetValue (3 overloads)	Gets a Avalonia.AvaloniaProperty value. Inherited from AvaloniaObject.
IsAnimating	Checks whether a Avalonia.AvaloniaProperty is animating. Inherited from AvaloniaObject.
IsSet	Checks whether a Avalonia.AvaloniaProperty is set on this object. Inherited from AvaloniaObject.
SetCurrentValue (2 overloads)	Sets the value of a dependency property without changing its value source. Inherited from AvaloniaObject.
SetValue (3 overloads)	Sets a Avalonia.AvaloniaProperty value. Inherited from AvaloniaObject.
VerifyAccess	Checks that the current thread is the UI thread and throws if not. Inherited from AvaloniaObject.

GetLayerBounds Method

Gets the geographic bounds (in 0-200, 0-100 viewport units) of the content in this layer. Used for auto-scaling the map to fit content.

Parameters

context Avalonia.Media.DrawingContext

The drawing context.

chartArea Avalonia.Rect

The chart area rectangle.

animationProgress double
