Summary:
Defines a land area geometry with cached path rendering for smooth zoom/pan. Re-implements the draw interface to bypass per-frame path rebuilding. Uses canvas matrix transform (GPU-accelerated) — zero allocations during zoom/pan.

Methods

// Marks the cached path as dirty, forcing a rebuild on the next draw. Call this after modifying the Commands collection.
// Sets a pre-built base path directly, bypassing the Commands-based path building. Used for combined geometries where multiple sub-paths need proper MoveTo calls.
SKPath path// The pre-built SKPath. Ownership is transferred to this geometry.
)
// Determines whether the specified point is inside this land polygon.
Single x, // *summary not found*
Single y// *summary not found*
)
// Draws the instance in the user interface with for the specified context.
SkiaSharpDrawingContext context//
)
// Completes the transition for the specified properties.
PropertyDefinition[] properties// The properties to complete, null to select all properties.
)
// Measures the instance.
// Sets the transition for the specified properties.
Animation animation, // The animation.
PropertyDefinition[] properties// The properties, null to select all properties.
)
// Removes the transition for the specified properties.
