Struct Transform

pub struct Transform {
    pub scale: f64,
    pub offset: f64,
}

A scale and an offset that transforms xyz coordinates.

Fields

scale: f64

The scale.

offset: f64

The offset.

Implementations

impl Transform

pub fn direct(&self, n: i32) -> f64

Applies this transform to an i32, returning a float.

Examples

use las::Transform;
let transform = Transform { scale: 2., offset: 1. };
assert_eq!(3., transform.direct(1));

pub fn inverse(&self, n: f64) -> Result<i32>

Applies the inverse transform, and rounds the result.

Returns an error if the resultant value can’t be represented as an i32.

Examples

use las::Transform;
let transform = Transform { scale: 2., offset: 1. };
assert_eq!(1, transform.inverse(2.9).unwrap());

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Transform

Returns the “default value” for a type.

impl Display for Transform

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

Formats the value using the given formatter.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> 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.
