[−][src]Struct kurbo::TranslateScale
A transformation including scaling and translation.
If the translation is (x, y)
and the scale is s
, then this
transformation represents this augmented matrix:
| s 0 x |
| 0 s y |
| 0 0 1 |
See Affine
for more details about the
equivalence with augmented matrices.
Various multiplication ops are defined, and these are all defined
to be consistent with matrix multiplication. Therefore,
TranslateScale * Point
is defined but not the other way around.
Also note that multiplication is not commutative. Thus,
TranslateScale::scale(2.0) * TranslateScale::translate(Vec2::new(1.0, 0.0))
has a translation of (2, 0), while
TranslateScale::translate(Vec2::new(1.0, 0.0)) * TranslateScale::scale(2.0)
has a translation of (1, 0). (Both have a scale of 2; also note that
the first case can be written
2.0 * TranslateScale::translate(Vec2::new(1.0, 0.0))
as this case
has an implicit conversion).
This transformation is less powerful than Affine
, but can be applied
to more primitives, especially including Rect
.
Methods
impl TranslateScale
[src]
pub const fn new(translation: Vec2, scale: f64) -> TranslateScale
[src]
Create a new transformation from translation and scale.
pub const fn scale(s: f64) -> TranslateScale
[src]
Create a new transformation with scale only.
pub const fn translate(t: Vec2) -> TranslateScale
[src]
Create a new transformation with translation only.
pub fn as_tuple(self) -> (Vec2, f64)
[src]
Decompose transformation into translation and scale.
pub fn inverse(self) -> TranslateScale
[src]
Compute the inverse transform.
Multiplying a transform with its inverse (either on the left or right) results in the identity transform (modulo floating point rounding errors).
Produces NaN values when scale is zero.
