HandleSnapGeometry

When dragging a handle, users can snap the handle to key geometry on other nearby shapes. Customize how handles snap to a shape by returning this from ShapeUtil.getHandleSnapGeometry.

Any co-ordinates here should be in the shape's local space.

interface HandleSnapGeometry {}

Properties

A Geometry2d that describe the outline of the shape that the handle will snap to - fills are ignored. By default, this is the same geometry returned by ShapeUtil.getGeometry. Set this to null to disable handle snapping to this shape's outline.

outline?: Geometry2d | null

Key points on the shape that the handle will snap to. For example, the corners of a rectangle, or the centroid of a triangle. By default, no points are used.

points?: VecModel[]

Methods

By default, handles can't snap to their own shape because moving the handle might change the snapping location which can cause feedback loops. You can override this by returning a version of outline that won't be affected by the current handle's position to use for self-snapping.

Parameters

TLHandle

Returns

Geometry2d | null

By default, handles can't snap to their own shape because moving the handle might change the snapping location which can cause feedback loops. You can override this by returning a version of points that won't be affected by the current handle's position to use for self-snapping.

Parameters
