Variants

Matrix(GenericMatrix<f32>)

Represents a 2D 2x3 matrix.

Matrix3D(GenericMatrix3D<f32>)

Represents a 3D 4x4 matrix.

Skew(Angle, Angle)

A 2D skew.

If the second angle is not provided it is assumed zero.

Syntax can be skew(angle) or skew(angle, angle)

SkewX(Angle)

skewX(angle)

SkewY(Angle)

skewY(angle)

Translate(LengthPercentage, LengthPercentage)

translate(x, y) or translate(x)

TranslateX(LengthPercentage)

translateX(x)

TranslateY(LengthPercentage)

translateY(y)

TranslateZ(CSSPixelLength)

translateZ(z)

Translate3D(LengthPercentage, LengthPercentage, CSSPixelLength)

translate3d(x, y, z)

Scale(f32, f32)

A 2D scaling factor.

Syntax can be scale(factor) or scale(factor, factor)

ScaleX(f32)

scaleX(factor)

ScaleY(f32)

scaleY(factor)

ScaleZ(f32)

scaleZ(factor)

Scale3D(f32, f32, f32)

scale3D(factorX, factorY, factorZ)

Rotate(Angle)

Describes a 2D Rotation.

In a 3D scene rotate(angle) is equivalent to rotateZ(angle).

RotateX(Angle)

Rotation in 3D space around the x-axis.

RotateY(Angle)

Rotation in 3D space around the y-axis.

RotateZ(Angle)

Rotation in 3D space around the z-axis.

Rotate3D(f32, f32, f32, Angle)

Rotation in 3D space.

Generalization of rotateX, rotateY and rotateZ.

Perspective(GenericPerspectiveFunction<CSSPixelLength>)

Specifies a perspective projection matrix.

Part of CSS Transform Module Level 2 and defined at § 13.1. 3D Transform Function.

The value must be greater than or equal to zero.

InterpolateMatrix

Fields

from_list: GenericTransform<GenericTransformOperation<Angle, f32, CSSPixelLength, i32, LengthPercentage>>

to_list: GenericTransform<GenericTransformOperation<Angle, f32, CSSPixelLength, i32, LengthPercentage>>

progress: Percentage

A intermediate type for interpolation of mismatched transform lists.

AccumulateMatrix

Fields

from_list: GenericTransform<GenericTransformOperation<Angle, f32, CSSPixelLength, i32, LengthPercentage>>

to_list: GenericTransform<GenericTransformOperation<Angle, f32, CSSPixelLength, i32, LengthPercentage>>

count: i32

A intermediate type for accumulation of mismatched transform lists.

Implementations

impl TransformOperation

fn try_animate_mismatched_transforms_in_place( left: &[Self], right: &[Self], procedure: Procedure ) -> Result<Self, ()>

If there are no size dependencies, we try to animate in-place, to avoid creating deeply nested Interpolate* operations.

fn animate_mismatched_transforms( left: &[Self], right: &[Self], procedure: Procedure ) -> Result<Self, ()>

impl TransformOperation

pub fn to_translate_3d(&self) -> Self

Convert to a Translate3D.

Must be called on a Translate function

pub fn to_rotate_3d(&self) -> Self

Convert to a Rotate3D.

Must be called on a Rotate function.

pub fn to_scale_3d(&self) -> Self

Convert to a Scale3D.

Must be called on a Scale function

Trait Implementations

impl Animate for TransformOperation

http://dev.w3.org/csswg/css-transforms/#interpolation-of-transforms

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl ComputeSquaredDistance for TransformOperation

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl ToAnimatedZero for TransformOperation

Build an equivalent ‘identity transform function list’ based on an existing transform list. http://dev.w3.org/csswg/css-transforms/#none-transform-animation

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.
