Implementations§

Source§

impl UiGlobalTransform

Source

pub fn try_inverse(&self) -> Option<Affine2>

If the transform is invertible returns its inverse. Otherwise returns None.

Methods from Deref<Target = Affine2>§

Source

pub const ZERO: Affine2

Source

pub const IDENTITY: Affine2

Source

pub const NAN: Affine2

Source

pub fn to_cols_array(&self) -> [f32; 6]

Creates a [f32; 6] array storing data in column major order.

Source

pub fn to_cols_array_2d(&self) -> [[f32; 2]; 3]

Creates a [[f32; 2]; 3] 2D array storing data in column major order. If you require data in row major order transpose the matrix first.

Source

pub fn transform_point2(&self, rhs: Vec2) -> Vec2

Transforms the given 2D point, applying shear, scale, rotation and translation.

Source

pub fn transform_vector2(&self, rhs: Vec2) -> Vec2

Transforms the given 2D vector, applying shear, scale and rotation (but NOT translation).

To also apply translation, use Self::transform_point2() instead.

Source

pub fn is_finite(&self) -> bool

Returns true if, and only if, all elements are finite.

If any element is either NaN, positive or negative infinity, this will return false.

Source

pub fn is_nan(&self) -> bool

Returns true if any elements are NaN.

Source

pub fn abs_diff_eq(&self, rhs: Affine2, max_abs_diff: f32) -> bool

Returns true if the absolute difference of all elements between self and rhs is less than or equal to max_abs_diff.

This can be used to compare if two 3x4 matrices contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

For more see comparing floating point numbers.

Source

pub fn inverse(&self) -> Affine2

Return the inverse of this transform.

Note that if the transform is not invertible the result will be invalid.

Source

pub fn as_daffine2(&self) -> DAffine2

Casts all elements of self to f64.
