Struct ScalingConfig 

Source 
pub struct ScalingConfig {
    pub scale: f64,
    pub inv_scale: f64,
}
Expand description

Configuration for coordinate scaling.

Fields§

§scale: f64

The scale factor (coordinates are multiplied by this value).

§inv_scale: f64

The inverse scale factor (for converting back).

Implementations§

Source§

impl ScalingConfig

Source

pub fn new(precision: u32) -> Self

Creates a new scaling configuration.

§Arguments
  • precision - Number of decimal places to preserve
§Example
use u_nesting_core::robust::ScalingConfig;

// Preserve 3 decimal places
let config = ScalingConfig::new(3);
assert_eq!(config.scale, 1000.0);
Source

pub fn scale_coord(&self, x: f64) -> f64

Scales a coordinate to integer range.

Source

pub fn scale_point(&self, p: (f64, f64)) -> (f64, f64)

Scales a point to integer range.

Source

pub fn unscale_coord(&self, x: f64) -> f64

Unscales a coordinate back to original range.

Source

pub fn unscale_point(&self, p: (f64, f64)) -> (f64, f64)

Unscales a point back to original range.

Source

pub fn scale_polygon(&self, polygon: &[(f64, f64)]) -> Vec<(f64, f64)>

Scales an entire polygon.

Source

pub fn unscale_polygon(&self, polygon: &[(f64, f64)]) -> Vec<(f64, f64)>

Unscales an entire polygon.
