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

Type: gint

The stroke ID.

precision

Type: gdouble

The precision used for the approximation.

num_coords

Type: gint*

The number of floats returned.

The argument will be set by the function.
closed

Type: gboolean*

Whether the stroke is closed or not.

The argument will be set by the function.

Return value

Type: 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.
