[−][src]Struct kurbo::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.
