void | SetColor (Color color) |
Color | GetColor () const |
bool | IsSolidColor () const override |
bool | IsOpaque (const Matrix &transform) const override |
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... | |
std::optional< Rect > | GetCoverage (const Entity &entity) const override |
Get the area of the render pass that will be affected when this contents is rendered. More... | |
bool | Render (const ContentContext &renderer, const Entity &entity, RenderPass &pass) const override |
std::optional< Color > | AsBackgroundColor (const Entity &entity, ISize target_size) const override |
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... | |
bool | ApplyColorFilter (const ColorFilterProc &color_filter_proc) override |
If possible, applies a color filter to this contents inputs on the CPU. More... | |

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... | |

Get the opacity factor for this color source. More... | |
void | SetInheritedOpacity (Scalar opacity) override |
Inherit the provided opacity. More... | |

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... | |

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... | |

If possible, applies a color filter to this contents inputs on the CPU.
This method will either fully apply the color filter or perform no action. Partial/incorrect application of the color filter will never occur.
[in] | color_filter_proc | A function that filters a given unpremultiplied color to produce a new unpremultiplied color. |
Reimplemented from impeller::Contents.
Definition at line 81 of file solid_color_contents.cc.

overridevirtual |
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.
This is useful for absorbing full screen solid color draws into subpass clear colors.

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.

result means that rendering this contents has no effect on the output color. Reimplemented from impeller::ColorSourceContents.
