Struct LayerTransform 

pub struct LayerTransform {
    pub x: f32,
    pub y: f32,
    pub scale_x: f32,
    pub scale_y: f32,
    pub rotation: f32,
}

2D affine transform parameters for a compositor layer.

All values use UV-space coordinates where 0.0 is no change. The default (identity) transform leaves the layer centred and unscaled.

Fields

x: f32

Horizontal UV-space offset (positive = shift right). Default: 0.0.

y: f32

Vertical UV-space offset (positive = shift down). Default: 0.0.

scale_x: f32

Horizontal scale factor (1.0 = no change). Default: 1.0.

scale_y: f32

Vertical scale factor (1.0 = no change). Default: 1.0.

rotation: f32

Counter-clockwise rotation in radians. Default: 0.0.

Implementations

impl LayerTransform

pub fn is_identity(&self) -> bool

Returns true when this transform is the identity (no visual change).

Trait Implementations

impl Clone for LayerTransform

fn clone(&self) -> LayerTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerTransform

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

Formats the value using the given formatter.

impl Default for LayerTransform

fn default() -> Self

Returns the “default value” for a type.
