Public Member Functions | |
| SrgbToLinearFilterContents () | |
| ~SrgbToLinearFilterContents () override | |
 Public Member Functions inherited from impeller::ColorFilterContents | |
| ColorFilterContents () | |
| ~ColorFilterContents () override | |
| void | SetAbsorbOpacity (AbsorbOpacity absorb_opacity) |
| AbsorbOpacity | GetAbsorbOpacity () const |
| void | SetAlpha (Scalar alpha) |
| Sets an alpha that is applied to the final blended result. More... | |
| std::optional< Scalar > | GetAlpha () const |
| Public Member Functions inherited from impeller::FilterContents | |
| FilterContents () | |
| ~FilterContents () override | |
| void | SetInputs (FilterInput::Vector inputs) |
| The input texture sources for this filter. Each input's emitted texture is expected to have premultiplied alpha colors. More... | |
| void | SetEffectTransform (const Matrix &effect_transform) |
| Sets the transform which gets appended to the effect of this filter. Note that this is in addition to the entity's transform. More... | |
| std::optional< Entity > | GetEntity (const ContentContext &renderer, const Entity &entity, const std::optional< Rect > &coverage_hint) const |
| Create an Entity that renders this filter's output. More... | |
| bool | Render (const ContentContext &renderer, const Entity &entity, RenderPass &pass) const override |
| std::optional< Rect > | GetCoverage (const Entity &entity) const override |
| Get the screen space bounding rectangle that this contents affects. More... | |
| void | PopulateGlyphAtlas (const std::shared_ptr< LazyGlyphAtlas > &lazy_glyph_atlas, Scalar scale) override |
| Add any text data to the specified lazy atlas. The scale parameter must be used again later when drawing the text. More... | |
| std::optional< Snapshot > | RenderToSnapshot (const ContentContext &renderer, const Entity &entity, std::optional< Rect > coverage_limit=std::nullopt, const std::optional< SamplerDescriptor > &sampler_descriptor=std::nullopt, bool msaa_enabled=true, const std::string &label="Filter Snapshot") const override |
Render this contents to a snapshot, respecting the entity's transform, path, stencil depth, and blend mode. The result texture size is always the size of GetCoverage(entity). More... | |
| const FilterContents * | AsFilter () const override |
Cast to a filter. Returns nullptr if this Contents is not a filter. More... | |
| virtual Matrix | GetLocalTransform (const Matrix &parent_transform) const |
| Matrix | GetTransform (const Matrix &parent_transform) const |
| virtual bool | IsTranslationOnly () const |
| Returns true if this filter graph doesn't perform any basis transformations to the filtered content. For example: Rotating, scaling, and skewing are all basis transformations, but translating is not. More... | |
| bool | IsLeaf () const |
Returns true if this filter does not have any FilterInput children. More... | |
| void | SetLeafInputs (const FilterInput::Vector &inputs) |
Replaces the set of all leaf FilterContents with a new set of FilterInputs. More... | |
| virtual void | SetRenderingMode (Entity::RenderingMode rendering_mode) |
| Marks this filter chain as applying in a subpass scenario. 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 |
| 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 StencilCoverage | GetStencilCoverage (const Entity &entity, const std::optional< Rect > ¤t_stencil_coverage) const |
| Given the current screen space bounding rectangle of the stencil, return the expected stencil coverage after this draw call. This should only be implemented for contents that may write to the stencil buffer. More... | |
| virtual bool | ShouldRender (const Entity &entity, const std::optional< Rect > &stencil_coverage) const |
| std::optional< Size > | GetColorSourceSize () const |
| Return the color source's intrinsic size, if available. More... | |
| void | SetColorSourceSize (Size size) |
| virtual bool | CanInheritOpacity (const Entity &entity) const |
| Whether or not this contents can accept the opacity peephole optimization. More... | |
| 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... | |
