### Method

# Gimp Vectors stroke_interpolate

#### Declaration [src]

    gdouble*
    gimp_vectors_stroke_interpolate (
      GimpVectors* vectors,
      gint stroke_id,
      gdouble precision,
      gint* num_coords,
      gboolean* closed
    )

#### Description [src]

Returns polygonal approximation of the stroke.

returns polygonal approximation of the stroke.

Available since: | 2.4

#### Parameters

`stroke_id` | `gint`
| The stroke ID.
`precision` | `gdouble`
| The precision used for the approximation.
`num_coords` | `gint*`
| The number of floats returned.
| The argument will be set by the function.
`closed` | `gboolean*`
| Whether the stroke is closed or not.
| The argument will be set by the function.

#### Return value

Returns: | An array of `double`
         List of the coords along the path (x0, y0, x1, y1, ...).
         The returned value must be freed with g_free().
| The length of the array is in the `num_coords` argument.
| The caller of the method takes ownership of the data, and is responsible for freeing it.
