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>
impl<'a> SaveLayerRec<'a>
pub fn bounds(self, bounds: &'a Rect) -> 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>
pub fn paint(self, paint: &'a Handle<SkPaint>) -> SaveLayerRec<'a>
Modifies overlay
pub fn backdrop(self, backdrop: &'a RCHandle<SkImageFilter>) -> SaveLayerRec<'a>
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>
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>
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>
pub fn flags(self, flags: SaveLayerFlags) -> SaveLayerRec<'a>
Preserves LCD text, creates with prior layer contents
