title: "PathIterator"
description: "A path iterator can be used to iterate over all the [segments][PathSegment] that make up a path.
Those segments may in turn define multiple contours inside the path. Conic segments are by
default evaluated as approximated quadratic segments. To preserve conic segments as conics, set
[conicEvaluation] to [AsConic][ConicEvaluation.AsConic]. The error of the approximation is
controlled by [tolerance].

A [PathIterator] can be created implicitly through a given [Path] object: using one of the two
[Path.iterator] functions."

A path iterator can be used to iterate over all the `segments` that make up a path.
Those segments may in turn define multiple contours inside the path. Conic segments are by
default evaluated as approximated quadratic segments. To preserve conic segments as conics, set
`conicEvaluation` to `AsConic`. The error of the approximation is
controlled by `tolerance`.

A `PathIterator` can be created implicitly through a given `Path` object: using one of the two
`Path.iterator` functions.

#### Parameters

| | |
| --- | --- |
| path | The `Path` to iterate over |
| conicEvaluation | Indicates how to evaluate conic segments |
| tolerance | When `conicEvaluation` is set to `PathIterator.ConicEvaluation.AsQuadratics` defines the maximum distance between the original conic curve and its quadratic approximations |
