Struct WindowLevel 

pub struct WindowLevel {
    pub center: f64,
    pub width: f64,
}

DICOM window/level parameters.

• center — the value that maps to the midpoint of the output range.
• width — the full span of input values that map to the full output range.

A width of zero is not meaningful; the caller should ensure width > 0.

Fields

center: f64

Window centre (level).

width: f64

Window width.

Implementations

impl WindowLevel

pub fn new(center: f64, width: f64) -> Self

Create from center and width.

Panics (debug only)

Panics in debug builds if width <= 0.

pub fn apply(&self, value: f64, out_min: f64, out_max: f64) -> f64

Apply the DICOM linear mapping and return a value in [out_min, out_max].

out_min and out_max are typically 0.0 and 1.0 for GPU normalisation, or 0.0 and 255.0 for 8-bit display.

pub fn normalise(&self, value: f64) -> f64

Normalise value to [0, 1] using the window mapping.

pub fn denormalise(&self, t: f64) -> f64

Return the input value that maps to t ∈ [0, 1].

This is the inverse of WindowLevel::normalise.

pub fn adjust_center(&mut self, delta: f64)

Adjust the center by delta (level change).

pub fn adjust_width(&mut self, factor: f64)

Adjust the width by factor (window change, multiplicative).

The width is clamped to at least 1.0 to avoid division by zero.

pub fn from_scalar_range(min: f64, max: f64) -> Self

Derive window/level from a scalar range.

Sets center to the midpoint and width to the full range (minimum 1.0).

Trait Implementations

impl Clone for WindowLevel

fn clone(&self) -> WindowLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WindowLevel

impl Debug for WindowLevel

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

Formats the value using the given formatter.

impl PartialEq for WindowLevel

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