[−][src]Struct pointy::Transform32

pub struct Transform32 { /* fields omitted */ }

An affine transform for Pt32 values.

A series of translate, rotate, scale and skew transformations can be combined into a single Transform32.

Example

use pointy::{Pt32, Transform32};

let t = Transform32::with_translate(-50.0, -50.0)
    .rotate(std::f32::consts::PI)
    .translate(50.0, 50.0)
    .scale(2.0, 2.0);
let pt = Pt32(13.0, 5.5) * t;
let pt2 = (8.2, 4.7) * t;
let pt3 = t * (3.8, 9.6);
