[−][src]Struct footile::Transform
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(-50.0, -50.0) .rotate(PI) .translate(50.0, 50.0) .scale(2.0, 2.0);
