Struct iron_shapes::transform::Matrix2dTransform

pub struct Matrix2dTransform<T: CoordinateType> {
    matrix: Matrix2d<T>,
}

Description of a transformation in the euclidean plane by a 2x2 matrix A. Transforming a point p is computed by the matrix product A*p.

Fields

matrix: Matrix2d<T>

Implementations

impl<T: CoordinateType> Matrix2dTransform<T>

pub fn new(matrix: Matrix2d<T>) -> Self

Create a new transform based on a matrix.

pub fn new_rotation90(angle: Angle) -> Self

Create a rotation by an integer multiple of 90 degrees.

pub fn new_scaling(factor: T) -> Self

Create a scaling by a factor.

pub fn new_mirror_x() -> Self

Mirror at the x-axis.

pub fn new_mirror_y() -> Self

Mirror at the y-axis.

pub fn transform_point(&self, p: Point<T>) -> Point<T>

Apply the transformation to a single point.

pub fn to_matrix2d(&self) -> Matrix2d<T>

Return the matrix describing this transformation.

pub fn try_invert(&self) -> Option<Self>

Get the inverse transformation.

Trait Implementations

impl<T: Clone + CoordinateType> Clone for Matrix2dTransform<T>

fn clone(&self) -> Matrix2dTransform<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug + CoordinateType> Debug for Matrix2dTransform<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Matrix2dTransform<T>where T: Deserialize<'de> + CoordinateType,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Hash + CoordinateType> Hash for Matrix2dTransform<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq + CoordinateType> PartialEq<Matrix2dTransform<T>> for Matrix2dTransform<T>

fn eq(&self, other: &Matrix2dTransform<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Serialize for Matrix2dTransform<T>where T: Serialize + CoordinateType,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
