getTransformedRegionProperties

Callable

• getTransformedRegionProperties(region: RegionTransformSource, spatialTransformAST: Mapping): { controlPoints: Point2D[]; rotation: number }

---

• Transforms a region's control points and rotation from one coordinate frame to another using the supplied AST spatial mapping.

  For box-like regions (rectangle, ellipse, compass, and their annotation equivalents) the center is reprojected and the size is rescaled by the local Jacobian; for all other region types every control point is reprojected individually.

  ---

  Parameters

  • region: RegionTransformSource

    Source region geometry expressed in the origin frame.

  • spatialTransformAST: Mapping

    AST mapping from the origin frame to the target frame.

  Returns { controlPoints: Point2D[]; rotation: number }

  Transformed control points and rotation angle in the target frame.

  • controlPoints: Point2D[]

  • rotation: number
