Used for sampling curves along the profile's path. Any points more than the number of user-defined points will be evenly distributed among the curved edges. Then the remainders will be distributed to the most curved edges.
n_segments | The number of segments to sample along the path. Ideally it is higher than the number of points used to define the profile (profile->path_len). |
sample_straight_edges | Whether to sample points between vector handle control points. If this is true and there are only vector edges the straight edges will still be sampled. |
r_samples | Return array of points to put the sampled positions. Must have length n_segments. Fill the array with the sampled locations and if the point corresponds to a control point, its handle type. |
