Struct ImmutableLinearGradientBrush 

pub struct ImmutableLinearGradientBrush { /* private fields */ }

A brush that draws with a linear gradient.

Implementations

impl ImmutableLinearGradientBrush

pub fn new( gradient_stops: &[ImmutableGradientStop], opacity: f64, transform: Option<Rc<ImmutableTransform>>, transform_origin: Option<RelativePoint>, spread_method: GradientSpreadMethod, start_point: Option<RelativePoint>, end_point: Option<RelativePoint>, relative_transform: Option<Rc<ImmutableTransform>>, ) -> Self

Creates a brush. transform_origin defaults to the top left corner, start_point to the top left and end_point to the bottom right.

pub fn from_stops(gradient_stops: &[ImmutableGradientStop]) -> Self

Creates a fully opaque brush with the given stops and default values for everything else.

pub fn from_brush(source: &LinearGradientBrush) -> Self

Creates an immutable copy of source.

pub fn start_point(&self) -> RelativePoint

The start point for the gradient.

pub fn end_point(&self) -> RelativePoint

The end point for the gradient.

Methods from Deref<Target = ImmutableGradientBrush>

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

pub fn opacity(&self) -> f64

pub fn transform_origin(&self) -> RelativePoint

The transform origin of the brush.

pub fn spread_method(&self) -> GradientSpreadMethod

pub fn relative_transform(&self) -> Option<Rc<dyn ITransform>>

Trait Implementations

impl Clone for ImmutableLinearGradientBrush

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Deref for ImmutableLinearGradientBrush

type Target = ImmutableGradientBrush

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl IBrush for ImmutableLinearGradientBrush

fn opacity(&self) -> f64

The opacity of the brush.

fn transform(&self) -> Option<Rc<dyn ITransform>>

The transform of the brush.

fn transform_origin(&self) -> RelativePoint

The origin of the brush transform.

fn relative_transform(&self) -> Option<Rc<dyn ITransform>>

The transform of the brush, relative to the bounds of the painted area.

fn as_immutable_brush(&self) -> Option<&dyn IImmutableBrush>

The brush viewed as IImmutableBrush, when it is one (the is IImmutableBrush test of upstream).

fn as_any(&self) -> &dyn Any

The implementing value, for downcasts to immutable brush types. For mutable brushes use as_object.

fn as_gradient_brush(&self) -> Option<&dyn IGradientBrush>

The brush viewed as IGradientBrush, when it is one.

fn as_linear_gradient_brush(&self) -> Option<&dyn ILinearGradientBrush>

The brush viewed as ILinearGradientBrush, when it is one.

fn into_immutable_brush(self: Rc<Self>) -> Option<Rc<dyn IImmutableBrush>>

The brush as an IImmutableBrush handle, when it is immutable.

fn to_shared(&self) -> Option<SharedBrush>

The form of the brush that is sent to the render thread, when the type keeps one: see SharedBrush. An immutable brush creates it once, so its identity is stable.

fn as_object(&self) -> Option<&FerroObject>

The object behind the brush when it is a mutable Brush.

fn as_solid_color_brush(&self) -> Option<&dyn ISolidColorBrush>

The brush viewed as ISolidColorBrush, when it is one.

fn as_radial_gradient_brush(&self) -> Option<&dyn IRadialGradientBrush>

The brush viewed as IRadialGradientBrush, when it is one.

fn as_conic_gradient_brush(&self) -> Option<&dyn IConicGradientBrush>

The brush viewed as IConicGradientBrush, when it is one.

fn as_tile_brush(&self) -> Option<&dyn ITileBrush>

The brush viewed as ITileBrush, when it is one.

fn as_image_brush(&self) -> Option<&dyn IImageBrush>

The brush viewed as IImageBrush, when it is one.

fn as_scene_brush(&self) -> Option<&dyn ISceneBrush>

The brush viewed as ISceneBrush, when it is one.

fn as_mutable_brush(&self) -> Option<&dyn IMutableBrush>

The brush viewed as IMutableBrush, when it is one.

fn as_composition_render_resource( &self, ) -> Option<&dyn ICompositionRenderResource>

The composition render resource behind the object, if it is a mutable object with server-side counterparts on the compositors it is drawn with.

fn as_composition_brush(&self) -> Option<&CompositionBrush>

The brush as a composition brush, when it is one (the is CompositionBrush test of upstream).

fn equals(&self, other: &dyn IBrush) -> bool

Whether the brush equals other. Brushes compare by reference unless the type defines structural equality (immutable solid color brushes).

impl IGradientBrush for ImmutableLinearGradientBrush

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

The brush’s gradient stops.

fn spread_method(&self) -> GradientSpreadMethod

The brush’s spread method that defines how to draw a gradient that doesn’t fill the bounds of the destination control.

impl IImmutableBrush for ImmutableLinearGradientBrush

impl ILinearGradientBrush for ImmutableLinearGradientBrush

fn start_point(&self) -> RelativePoint

The start point for the gradient.

fn end_point(&self) -> RelativePoint

The end point for the gradient.
