Struct iron_shapes::transform::SimpleTransform

pub struct SimpleTransform<T: CoordinateType> {
    pub mirror: bool,
    pub rotation: Angle,
    pub magnification: T,
    pub displacement: Vector<T>,
}

Describes a geometric transformation that consists of a optional mirroring along the x-axis followed by a rotation by a multiple of 90 degrees followed by a displacement.

Fields

mirror: bool

Mirror on the x-axis?

rotation: Angle

Rotation by a multiple of 90 degrees.

magnification: T

Enlargement.

displacement: Vector<T>

Translation.
