Struct footile::Transform
[−]
[src]
pub struct Transform { /* fields omitted */ }
An affine transform can translate, scale, rotate and skew 2D points.
A series of transforms can be combined into a single Transform struct. This can be used by a Plotter to alter subsequent points.
Example
use footile::Transform; const PI: f32 = std::f32::consts::PI; let t = Transform::new_translate(-50f32, -50f32) .rotate(PI) .translate(50f32, 50f32) .scale(2f32, 2f32);
