Struct vizia::vg::canvas::SaveLayerRec

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

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 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

Formats the value using the given formatter.

impl<'a> Default for SaveLayerRec<'a>

fn default() -> SaveLayerRec<'a>

Sets Self::bounds, Self::paint, and Self::backdrop to None. Clears Self::flags.

Returns empty SaveLayerRec

impl Drop for SaveLayerRec<'_>

fn drop(&mut self)

Executes the destructor for this type.
