Methods

applyingAffineTransform(containerSize:viewSize:transform:)

public func applyingAffineTransform(containerSize: CGSize, viewSize: CGSize, transform: CGAffineTransform) -> CGRect

Transforms a rectangle from the container coordinate space to view by applying a given affine transform to its corner points.

• Parameters:
  • containerSize: The size of the original container coordinate space.
  • viewSize: The size of the target view coordinate space.
  • transform: The affine transform to apply (expected to operate on normalized coordinates).
• Returns: A new rectangle transformed into the view coordinate space.

Parameters

Name	Description
containerSize	The size of the original container coordinate space.
viewSize	The size of the target view coordinate space.
transform	The affine transform to apply (expected to operate on normalized coordinates).

applyingReprojection(containerSize:transform:)

public func applyingReprojection(containerSize: CGSize, transform: simd_float3x3) -> CGRect

Applies a 3x3 homography (reprojection) to this rectangle and returns the resulting bounding box in a specified container coordinate space.

• Parameters:
  • containerSize: The size of the container coordinate space. Coordinates are assumed to be relative to this space (e.g., image or view size) when applying the homography.
  • transform: The 3x3 homography matrix that maps points from the source coordinate space to the target coordinate space.
• Returns: A new CGRect representing the transformed rectangle.

Parameters

Name	Description
containerSize	The size of the container coordinate space. Coordinates are assumed to be relative to this space (e.g., image or view size) when applying the homography.
transform	The 3x3 homography matrix that maps points from the source coordinate space to the target coordinate space.
