Modules

ink

Deterministic ink materials and pressure-sensitive drawing.

Structs

CompileCache

A compile cache created from one immutable key.

Morph

Prepared, replayable semantic tree morph. Leaf IDs take priority, followed by position and signed-curve-area magnitude. Unmatched parts grow/shrink at their own center. Fill/stroke/image geometry shares MorphPath’s original curves. Spatial paints and differing clipping/isolation crossfade the two retained hierarchies; solid colors interpolate in Oklab on the morphed geometry.

SurfaceTriangle

A nondegenerate tree-space triangle in a filled geometric union.

VectorGroup

A shared coordinate/isolation group, including source provenance.

VectorImage

A bitmap leaf; its surrounding group supplies any affine placement.

VectorLeaf

A leaf occurrence with complete world coordinates and inherited metadata.

VectorMask

A shared coordinate/isolation group, including source provenance.

VectorPath

A painted path in its containing group’s local coordinates.

VectorSelection

Authored modifier applied to the original vector groups at known addresses.

VectorSurface

Immutable prepared fill silhouette for deterministic area-uniform sampling. Images/strokes are not filled path regions. Paint alpha is not a density; zero-opacity groups are omitted, clips/holes and overlapping fills are honored.

VectorTree

Immutable, cheaply cloned group/path/image tree with unique ID lookup. Construction validates every branch, including invisible ones, under bounded depth (48), items (8192), IDs (1024 bytes each) and aggregate verbs (262144).

WriteOptions

Shared cumulative-length handwriting and fill handoff settings.

Enums

VectorItem

A semantic leaf or group, retained in paint order.
