Struct Transform2D

pub struct Transform2D {
    pub previous: Option<Box<Transform2D>>,
    pub rotate: Option<Rotation>,
    pub translate: Option<[Size; 2]>,
    pub anchor: Option<[Size; 2]>,
    pub scale: Option<[Size; 2]>,
    pub skew: Option<[Rotation; 2]>,
}

A sugary representation of an Affine transform+, including anchor and align as layout-computed properties.

translate represents an (x,y) affine translation scale represents an (x,y) non-uniform affine scale rotate represents a (z) affine rotation (intuitive 2D rotation) anchor represents the “(0,0)” point of the render node as it relates to its own bounding box. By default that’s the top-left of the element, but anchor allows that to be offset either by a pixel or percentage-of-element-size for each of (x,y)

Fields

previous: Option<Box<Transform2D>>

Keeps track of a linked list of previous Transform2Ds, assembled e.g. via multiplication

rotate: Option<Rotation>

Rotation is single-dimensional for 2D rendering, representing rotation over z axis

translate: Option<[Size; 2]>

anchor: Option<[Size; 2]>

scale: Option<[Size; 2]>

skew: Option<[Rotation; 2]>

Implementations

impl Reflectable for Transform2D

fn get_import_path() -> String
