Implementations

impl PolygonRegion

pub fn polygon_points(&self) -> Vec<(i32, i32)>

Get the points in a polygon region.

This returns the values in the reference coordinate space (from the parent region item).

A polygon is a sequence of points that form a closed shape. The first point does not need to be repeated as the last point. All the interior points and the edge are part of the region. The points are returned as pairs of (X, Y) coordinates.

pub fn polygon_points_transformed(&self, image_id: ItemId) -> Vec<(f64, f64)>

Get the transformed points in a polygon region.

This returns the coordinates in pixels after all transformative properties have been applied.

A polygon is a sequence of points that form a closed shape. The first point does not need to be repeated as the last point. All the interior points and the edge are part of the region. The points are returned as pairs of (X, Y) coordinates.
