Struct CompositionGradientBrush 

pub struct CompositionGradientBrush(/* private fields */);

The base of the composition gradient brushes: the gradient stops and the spread method.

Implementations

impl CompositionGradientBrush

pub fn from_brush( brush: &Rc<CompositionBrush>, ) -> Option<CompositionGradientBrush>

The handle of brush as a gradient brush, if it is one.

pub fn gradient_stops(&self) -> FerroList<Rc<dyn IGradientStop>>

The gradient stops. Mutations of the list itself are not tracked - assign the property to ship in-place edits made after a commit. Stops created via Compositor::create_gradient_stop_with stay live on the server and animate individually; other stops are snapshotted at serialization time.

pub fn set_gradient_stops(&self, value: FerroList<Rc<dyn IGradientStop>>)

pub fn spread_method(&self) -> GradientSpreadMethod

How the gradient repeats outside the stop range.

pub fn set_spread_method(&self, value: GradientSpreadMethod)

impl CompositionGradientBrush

pub fn anchor_point(&self) -> Vector

The point of the gradient, relative to the size of the painted area, that is placed at offset (animatable as AnchorPoint).

pub fn set_anchor_point(&self, value: Vector)

pub fn center_point(&self) -> Vector

The point the gradient is scaled and rotated about, in the coordinates of the painted area (animatable as CenterPoint).

pub fn set_center_point(&self, value: Vector)

pub fn offset(&self) -> Vector

The offset of the gradient (animatable as Offset).

pub fn set_offset(&self, value: Vector)

pub fn rotation_angle(&self) -> f32

The rotation of the gradient about its centre point, in radians (animatable as RotationAngle).

pub fn set_rotation_angle(&self, value: f32)

pub fn scale(&self) -> Vector

The scale of the gradient about its centre point (default (1, 1); animatable as Scale).

pub fn set_scale(&self, value: Vector)

pub fn transform_matrix(&self) -> Matrix

The transform matrix of the gradient (WinUI Matrix3x2; animatable as TransformMatrix).

pub fn set_transform_matrix(&self, value: Matrix)

impl CompositionGradientBrush

pub fn rotation_angle_in_degrees(&self) -> f32

The rotation in degrees: a view of rotation_angle (not an animation target).

pub fn set_rotation_angle_in_degrees(&self, value: f32)

pub fn extend_mode(&self) -> CompositionGradientExtendMode

How the gradient continues outside its stops: a view of spread_method (Clamp is Pad, Wrap is Repeat, Mirror is Reflect).

pub fn set_extend_mode(&self, value: CompositionGradientExtendMode)

pub fn interpolation_space(&self) -> CompositionColorSpace

The colour space the stops are interpolated in.

Deviation (winui-composition.md): stored only; the drawing contexts interpolate in RGB.

pub fn set_interpolation_space(&self, value: CompositionColorSpace)

pub fn mapping_mode(&self) -> CompositionMappingMode

How the points of the WinUI members are measured (default Relative). Changing it keeps the numbers of the points and changes their unit, as WinUI reads the same numbers in the new mode.

pub fn set_mapping_mode(&self, value: CompositionMappingMode)

pub fn color_stops(&self) -> FerroList<Rc<dyn IGradientStop>>

ColorStops: the WinUI name of gradient_stops, with the same rule: a change of the list itself is shipped when the list is assigned again (set_color_stops).

pub fn set_color_stops(&self, value: FerroList<Rc<dyn IGradientStop>>)

Trait Implementations
