Function: extractSubpath()
extractSubpath(
d,start,end):PathData
Defined in: attributes/shape/path/subpath.ts:472
Returns the portion of a path between the normalized arc-length fractions
start and end (both 0..1), as a fresh command list. This is what drives a
"trim path" / draw-on animation.
Fast paths: a full 0..1 range, a string d (already opaque), or an empty
path are returned unchanged; an empty/inverted range returns [].
Parameters
d
Source path (command array; strings pass through untouched).
start
number
Fraction of total length where the result begins (clamped to 0..1).
end
number
Fraction where it ends (clamped to start..1).
