PathCap

Path endpoint geometry.

PathCap controls how the start and end of a path are rendered. It is used with Cell.add_path() to select the cap style. Path corners use miter joins with a four-half-width limit and bevel fallback; round caps are approximated with 16 segments per semicircle.

cell.add_path(
    [Point(0, 0), Point(100, 0)],
    width=0.5,
    layer=Layer(1, 0),
    cap=PathCap.ROUND,
)

Variants

attributeFLUSHPathCap

Flush (square) ends at path endpoints. The path terminates exactly at the first and last point with no extension. This is the default.

attributeROUNDPathCap

Round ends. A semicircle with diameter equal to the path width magnitude is drawn at each endpoint.

attributeHALF_WIDTH_EXTENSIONPathCap

Square ends extending half the path width magnitude past the endpoints. Each end is extended by abs(width) / 2 along the path direction.
