[−][src]Struct kurbo::Affine

pub struct Affine(_);

A 2D affine transform.

Methods

`impl Affine`[src]

`pub fn new(c: [f64; 6]) -> Affine`[src]

Construct an affine transform from coefficients.

If the coefficients are (a, b, c, d, e, f), then the resulting transformation represents this augmented matrix:

| a c e |
| b d f |
| 0 0 1 |

Note that this convention is transposed from PostScript and Direct2D, but is consistent with the Wikipedia formulation of affine transformation as augmented matrix. The idea is that (A * B) * v == A * (B * v), where * is the Mul trait.

`pub fn scale(s: f64) -> Affine`[src]

An affine transform representing uniform scaling.

`pub fn rotate(th: f64) -> Affine`[src]

An affine transform representing rotation.

The convention for rotation is that a positive angle rotates a positive X direction into positive Y. Thus, in a Y-down coordinate system (as is common for graphics), it is a clockwise rotation, and in Y-up (traditional for math), it is anti-clockwise.

The angle, th, is expressed in radians.

`pub fn translate<V: Into<Vec2>>(p: V) -> Affine`[src]

An affine transform representing translation.

`pub fn as_coeffs(self) -> [f64; 6]`[src]

Get the coefficients of the transform.
