| void | SetBlendMode (BlendMode blend_mode) |
| void | SetChildContents (std::shared_ptr< Contents > child_contents) |
 Public Member Functions inherited from impeller::ColorSourceContents | |
| ColorSourceContents () | |
| ~ColorSourceContents () override | |
| void | SetGeometry (const Geometry *geometry) |
| Set the geometry that this contents will use to render. More... | |
| const Geometry * | GetGeometry () const |
| Get the geometry that this contents will use to render. More... | |
| void | SetEffectTransform (Matrix matrix) |
| Set the effect transform for this color source. More... | |
| const Matrix & | GetInverseEffectTransform () const |
| Set the inverted effect transform for this color source. More... | |
| void | SetOpacityFactor (Scalar opacity) |
| Set the opacity factor for this color source. More... | |
| Scalar | GetOpacityFactor () const |
| Get the opacity factor for this color source. More... | |
| virtual bool | IsSolidColor () const |
| void | SetInheritedOpacity (Scalar opacity) override |
| Inherit the provided opacity. More... | |
| Public Member Functions inherited from impeller::Contents | |
| Contents () | |
| virtual | ~Contents () |
| 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... | |
| virtual std::optional< Snapshot > | RenderToSnapshot (const ContentContext &renderer, const Entity &entity, const SnapshotOptions &options) const |
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 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... | |
