Struct shapefile::record::multipatch::Multipatch

pub struct Multipatch { /* fields omitted */ }

Shapefile’s Multipatch shape (p 24/34)

The following things are important with Multipatch shape:

1. Ring types must be closed (the various constructors will close the rings if you did not close them yourself)
2. InnerRings must follow their OuterRings (this is not checked)
3. Parts must not intersects or penetrate each others (this is not checked)
4. The points organization of TriangleStrip and TriangleFan is not checked

Implementations

impl Multipatch

pub fn new(patch: Patch) -> Self

Creates a Multipatch with one patch

The constructor closes rings patch

Examples

use shapefile::{PointZ, Multipatch, NO_DATA, Patch};
let points = vec![
    PointZ::new(0.0, 0.0, 0.0, NO_DATA),
    PointZ::new(0.0, 1.0, 0.0, NO_DATA),
    PointZ::new(1.0, 1.0, 0.0, NO_DATA),
    PointZ::new(1.0, 0.0, 0.0, NO_DATA),
];
let multip = Multipatch::new(Patch::OuterRing(points));

pub fn with_parts(patches: Vec<Patch>) -> Self

Creates a Multipatch with multiple patches

Closes any patch part that is a ring

Example

use shapefile::{PointZ, Multipatch, NO_DATA, Patch};
let multipatch = Multipatch::with_parts(vec![
    Patch::OuterRing(vec![
        PointZ::new(0.0, 0.0, 0.0, NO_DATA),
        PointZ::new(0.0, 4.0, 0.0, NO_DATA),
        PointZ::new(4.0, 4.0, 0.0, NO_DATA),
        PointZ::new(4.0, 0.0, 0.0, NO_DATA),
    ]),
    Patch::InnerRing(vec![
        PointZ::new(0.0, 0.0, 0.0, NO_DATA),
        PointZ::new(0.0, 2.0, 0.0, NO_DATA),
        PointZ::new(2.0, 2.0, 0.0, NO_DATA),
        PointZ::new(2.0, 0.0, 0.0, NO_DATA),
    ])
]);
