source

pub fn to_transform(self) -> Transform3D<f32, Px, Px>

To full transform.

source

pub fn is_identity(&self) -> bool

Returns true it is the identity transform.

source

pub fn then(&self, other: &PxTransform) -> PxTransform

Returns the multiplication of the two matrices such that mat’s transformation applies after self’s transformation.

source

pub fn then_translate(&self, offset: Vector2D<f32, Px>) -> PxTransform

Returns a transform with a translation applied after self’s transformation.

source

pub fn pre_translate(&self, offset: Vector2D<f32, Px>) -> PxTransform

Returns a transform with a translation applied before self’s transformation.

source

pub fn is_invertible(&self) -> bool

Returns whether it is possible to compute the inverse transform.

source

pub fn inverse(&self) -> Option<PxTransform>

Returns the inverse transform if possible.

source

pub fn is_2d(&self) -> bool

Returns true if this transform can be represented with a Transform2D.

source

pub fn transform_point(&self, point: PxPoint) -> Option<PxPoint>

Transform the pixel point.

Note that if the transform is 3D the point will be transformed with z=0, you can use project_point to find the 2D point in the 3D z-plane represented by the 3D transform.

source

pub fn transform_point_f32( &self, point: Point2D<f32, Px>, ) -> Option<Point2D<f32, Px>>

Note that if the transform is 3D the point will be transformed with z=0, you can use project_point_f32 to find the 2D point in the 3D z-plane represented by the 3D transform.

source

pub fn transform_vector(&self, vector: PxVector) -> PxVector

Transform the pixel vector.

source

pub fn transform_vector_f32( &self, vector: Vector2D<f32, Px>, ) -> Vector2D<f32, Px>

Transform the pixel vector.

source

pub fn project_point(&self, point: PxPoint) -> Option<PxPoint>

Project the 2D point onto the transform Z-plane.

source

pub fn project_point_f32( &self, point: Point2D<f32, Px>, ) -> Option<Point2D<f32, Px>>

Project the 2D point onto the transform Z-plane.

source

pub fn outer_transformed(&self, px_box: PxBox) -> Option<PxBox>

Returns a 2D box that encompasses the result of transforming the given box by this transform, if the transform makes sense for it, or None otherwise.

source

pub fn outer_transformed_f32( &self, px_box: Box2D<f32, Px>, ) -> Option<Box2D<f32, Px>>

Returns a 2D box that encompasses the result of transforming the given box by this transform, if the transform makes sense for it, or None otherwise.
