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 |
| void | SetInheritedOpacity (Scalar opacity) override |
| Inherit the provided opacity. More... | |
| std::optional< Rect > | GetFilterSourceCoverage (const Matrix &effect_transform, const Rect &output_limit) const override |
| Internal utility method for |GetSourceCoverage| that computes the inverse effect of this transform on the specified output coverage, ignoring the inputs which will be accommodated by the caller. More... | |
| 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 area of the render pass that will be affected when this contents is rendered. 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, int32_t mip_count=1, std::string_view label="Filter Snapshot") const override |
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< Rect > | GetSourceCoverage (const Matrix &effect_transform, const Rect &output_limit) const |
| Determines the coverage of source pixels that will be needed to produce results for the specified |output_limit| under the specified |effect_transform|. This is essentially a reverse of the |GetCoverage| method computing a source coverage from an intended |output_limit| coverage. More... | |
| virtual Matrix | GetLocalTransform (const Matrix &parent_transform) const |
| Matrix | GetTransform (const Matrix &parent_transform) const |
| 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 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... | |
| 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... | |
