Crate xpict_core 

Shared depiction core for xpict.

Python under python/xpict/ is still the working engine. This crate holds algorithms we are ready to share with PyO3 and WASM — start small, move modules as they stabilize. See the crate README.md for the migration rule.

Modules

align

Rigid 2D alignment (Kabsch) — Indigo / no-RDKit fallback.

arrows

Reaction / network edge shafts in document space.

bonds

Bond strokes: skeleton centerlines, multi-bond offsets, stereo, joins.

colormap

Vendored xenosite colormap (from xenopict._cm_def / Python _xenosite_cm).

cxsmiles

ChemAxon CXSMILES atom-label helpers.

depict

Single-molecule depiction: MoleculeIn → Scene.

doc

Declarative document — plan (pass 1) + paint (pass 2) + scheme compose.

edge

EdgePlan / EdgeResult — host callback ABI (coord_gen / align).

elements

Periodic table: atomic number ↔ element symbol.

elk

Multi-molecule diagram placement via elkrs (native ELK).

font

Bundled Liberation Sans outlines (ttf-parser).

geom

Geometry for halos and ink (Shapely stand-in).

labels

Atom-label orientation and backbone bond insets.

markup

Chem-label markup → ChemGlyphs.

metrics

Depiction proportions (xenopict / RDKit house style).

plotdot

Concentric plot-dot shading (xenopict PlotDot semantics).

rings

Practical SSSR and ring-interior normals for depiction.

scene

Drawable scene document — engine-neutral primitives shared by Python & JS.
