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... | |

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 | ~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 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... | |

Marks this filter chain as applying in a subpass scenario.
Subpasses render in screenspace, and this setting informs filters that the current transform matrix of the entity is not stored in the Entity transform matrix. Instead, the effect transform is used in this case.
