Module geom 

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

Capsule/disk helpers always available. Full multipolygon buffer / boolean ops live behind the geom feature (i_overlay) — enable for Python so Shapely can leave the runtime dependency set.

Structs

Shape

Multipolygon ink / halo geometry.

Functions

capsule_halo_path_d

White knockout path for a stroked capsule (ink radius + grow distance).

capsule_polygon

Filled capsule: segment (x1,y1)–(x2,y2) thickened by radius, round caps.

circle_polygon

Approximate a circle as a closed polygon (Shapely quad_segs style).

disk_halo_path_d

Disk ink halo (point buffer then grow → single circle at r + grow).

polygon_to_svg_d

Closed polygon as SVG path d (absolute M/L/Z).
