[−][src]Trait geo_normalized::Normalized
Required methods
fn normalized(&self) -> Self
This trait returns a new geo-types Polygon/Multipolygon that follows the OGC winding rules
The rust geo and geo-types crates are not as strict as the OGC guidelines, and allow for polygons with inner and outer rings in any winding order. This trait returns a Polygon/Multipolygon where all outer rings are clockwise, and all inner rings are anti-clockwise.
Examples
// Anti-clockwise winding order for outer ring let bad = polygon![ (x: 1.0, y: 1.0), (x: 4.0, y: 1.0), (x: 4.0, y: 4.0), (x: 1.0, y: 4.0), (x: 1.0, y: 1.0), ]; // Clockwise winding order for outer ring let good = polygon![ (x: 1.0, y: 1.0), (x: 1.0, y: 4.0), (x: 4.0, y: 4.0), (x: 4.0, y: 1.0), (x: 1.0, y: 1.0), ]; let norm = bad.normalized(); // norm should have the same points and shape as `bad` but in the valid winding order assert_eq!(norm, good);
