pub trait SimplifyIdx<T, Epsilon = T> {
fn simplify_idx(&self, epsilon: &T) -> Vec<usize>
where
T: GeoFloat;
}Expand description
Simplifies a geometry, returning the retained indices of the input.
This operation uses the Ramer–Douglas–Peucker algorithm and does not guarantee that the returned geometry is valid.
An epsilon less than or equal to zero will return an unaltered version of the geometry.
Required Methods
Returns the simplified indices of a geometry, using the Ramer–Douglas–Peucker algorithm
Examples
use geo::SimplifyIdx;
use geo::line_string;
let line_string = line_string![
(x: 0.0, y: 0.0),
(x: 5.0, y: 4.0),
(x: 11.0, y: 5.5),
(x: 17.3, y: 3.2),
(x: 27.8, y: 0.1),
];
let simplified = line_string.simplify_idx(&1.0);
let expected = vec![
0_usize,
1_usize,
2_usize,
4_usize,
];
assert_eq!(expected, simplified);
