Struct TransformAndBounds 

pub struct TransformAndBounds<F, T = F> {
    pub transform: Transform2<F, T>,
    pub bounds: (f64, f64),
}

Pax’s canonical representation of position, size, and transform, encoded as a transform (translation, rotation, scale, skew) and a separate width/height (bounds) value. Bounds are expressed as the (x1, y1) values of the axis-aligned pre-transform bounding box, where (x0, y0) are the origin.

In this model, position is a derived property, calculated by applying the transform to the bounding box.

Fields

transform: Transform2<F, T>

bounds: (f64, f64)

Implementations

impl<F: Space, T: Space> TransformAndBounds<F, T>

pub fn center(&self) -> Point2<T>
