CoordinateTransformer

Artifact: androidx.camera.viewfinder:viewfinder-compose

interface CoordinateTransformer

Known direct subclasses

IdentityCoordinateTransformer, MutableCoordinateTransformer

`IdentityCoordinateTransformer`	`CoordinateTransformer` where the transformMatrix is the identity matrix.
`MutableCoordinateTransformer`	CoordinateTransformer where the transformMatrix is mutable.

Coordinate transformer that's used to convert coordinates from one space to another.

transformMatrix must be set by whoever manipulates the coordinate space, otherwise an identity will be used for the coordinate transformations. When used in a Viewfinder, the viewfinder will set this transform matrix.

Summary
