void | SetCoverageHint (std::optional< Rect > coverage_hint) |
Hint that specifies the coverage area of this Contents that will actually be used during rendering. This is for optimization purposes only and can not be relied on as a clip. May optionally affect the result of GetCoverage() . More... | |
const std::optional< Rect > & | GetCoverageHint () const |
virtual bool | IsOpaque (const Matrix &transform) const |
Whether this Contents only emits opaque source colors from the fragment stage. This value does not account for any entity properties (e.g. the blend mode), clips/visibility culling, or inherited opacity. More... | |

Render this contents to a snapshot, respecting the entity's transform, path, clip depth, and blend mode. The result texture size is always the size of GetCoverage(entity) . More... | |
std::optional< Size > | GetColorSourceSize () const |
Return the color source's intrinsic size, if available. More... | |
void | SetColorSourceSize (Size size) |
virtual void | SetInheritedOpacity (Scalar opacity) |
Inherit the provided opacity. More... | |
virtual std::optional< Color > | AsBackgroundColor (const Entity &entity, ISize target_size) const |
Returns a color if this Contents will flood the given target_size with a color. This output color is the "Source" color that will be used for the Entity's blend operation. More... | |
virtual bool | ApplyColorFilter (const ColorFilterProc &color_filter_proc) |
If possible, applies a color filter to this contents inputs on the CPU. More... | |

Get the area of the render pass that will be affected when this contents is rendered.
During rendering, coverage coordinates count pixels from the top left corner of the framebuffer.
std::nullopt
result means that rendering this contents has no effect on the output color. Implements impeller::Contents.
