Struct SaveLayerRec

#[repr(C)]
pub struct SaveLayerRec<'a> { /* private fields */ }
Expand description

SaveLayerRec contains the state used to create the layer.

Implementations§

§

impl<'a> SaveLayerRec<'a>

pub fn bounds(self, bounds: &'a Rect) -> SaveLayerRec<'a>

Hints at layer size limit

pub fn paint(self, paint: &'a Handle<SkPaint>) -> SaveLayerRec<'a>

Modifies overlay

pub fn backdrop(self, backdrop: &'a RCHandle<SkImageFilter>) -> SaveLayerRec<'a>

If not None, this triggers the same initialization behavior as setting SaveLayerFlags::INIT_WITH_PREVIOUS on Self::flags: the current layer is copied into the new layer, rather than initializing the new layer with transparent-black. This is then filtered by Self::backdrop (respecting the current clip).

pub fn backdrop_tile_mode( self, backdrop_tile_mode: SkTileMode, ) -> SaveLayerRec<'a>

If the layer is initialized with prior content (and/or with a backdrop filter) and this would require sampling outside of the available backdrop, this is the tilemode applied to the boundary of the prior layer’s image.

pub fn color_space( self, color_space: &'a RCHandle<SkColorSpace>, ) -> SaveLayerRec<'a>

If not None, this triggers a color space conversion when the layer is restored. It will be as if the layer’s contents are drawn in this color space. Filters from backdrop and paint will be applied in this color space.

pub fn flags(self, flags: SaveLayerFlags) -> SaveLayerRec<'a>

Preserves LCD text, creates with prior layer contents

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
