donner::svg::FontDataRenderingOptions

struct donner::svg::FontDataRenderingOptions

Owned rendering attributes for a provider face reloaded from encoded bytes.

These values configure the new face before a backend can cache it. They do not name or query a provider, and do not associate the face with a CSS family.

Class Members
bool	genericSans = false	The source face belongs to the generic sans-serif provider.
bool	immutableCatalog = false	The source face belongs to an immutable font catalog.
optional< FontFaceRequest >	providerRequest	Requested weight, style and stretch.

donner::svg::FontLoadingDomainIdentity

struct donner::svg::FontLoadingDomainIdentity

Non-owning identity of an installed font-loading domain.

Compare owner control blocks, including after expiration. The allowance conservatively accounts for the fixed coallocation kept alive by a weak reference, not live font data or physical RSS.

Class Members
weak_ptr< const void >	owner	Does not retain the source or its resources.
size_t	retainedStorageBytes = 0	Conservative fixed weak-identity storage allowance.

donner::svg::FontManager::GlyphOutlineComplexity

struct donner::svg::FontManager::GlyphOutlineComplexity

Validation-time allocation/work bound for one font outline.

Class Members
size_t	maximumVertices = 0
size_t	work = 0
