Struct Similarity2 

pub struct Similarity2 { /* private fields */ }

A 2D affine transform whose linear part is a nonsingular similarity.

Implementations

impl Similarity2

pub fn try_from_f64_affine( a: f64, b: f64, d: f64, e: f64, xoff: f64, yoff: f64, tolerance: f64, ) -> CurveResult<Self>

Constructs a planar similarity from finite affine entries.

The transform is:

x' = a*x + b*y + xoff
y' = d*x + e*y + yoff

The finite validation tolerance is only used to accept API-boundary matrix entries as a similarity. Once accepted, all transformed geometry is built with hyperreal coefficients.

pub const fn reverses_orientation(&self) -> bool

Returns true when the transform reverses orientation.

pub fn transform_point(&self, point: &Point2) -> Point2

Transforms a point with hyperreal arithmetic.

Trait Implementations

impl Clone for Similarity2

fn clone(&self) -> Similarity2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Similarity2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Similarity2

fn eq(&self, other: &Similarity2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
