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, 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="Snapshot") 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... | |

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. |
