Struct 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) -> Self

Hints at layer size limit

pub fn paint(self, paint: &'a Paint) -> Self

Modifies overlay

pub fn backdrop(self, backdrop: &'a ImageFilter) -> Self

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: TileMode) -> Self

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 ColorSpace) -> Self

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) -> Self

Preserves LCD text, creates with prior layer contents
