Struct BoxTransform 

pub struct BoxTransform {
    pub rect: Rect,
    pub angle: f32,
    pub pivot: Point,
}

A rectangle turned around a point, which is what a TransformHandles edits.

Fields

rect: Rect

The box before turning, in the units of the content.

angle: f32

How far it is turned clockwise, in degrees.

pivot: Point

The point it turns around, as a share of the box: (0.5, 0.5) is its middle.

Implementations

impl BoxTransform

pub const fn new(rect: Rect) -> Self

An upright box that turns around its middle.

pub const fn rotated(self, angle: f32) -> Self

The same box turned clockwise by this many degrees.

pub fn pivot_point(&self) -> Point

The point it turns around, in the units of the content.

pub fn to_world(&self, local: Point) -> Point

Where a point of the upright box ends up once turned.

pub fn to_local(&self, world: Point) -> Point

The point of the upright box that ends up at world once turned.

pub fn corners(&self) -> [Point; 4]

The four corners once turned, clockwise from what was the top left.

pub fn handle(&self, handle: BoxHandle) -> Point

Where a handle is once turned.
