FixedRange

Struct FixedRange

pub struct FixedRange { /* private fields */ }

Expand description

Display with a fixed, user-specified value range.

Values at min map to black, values at max map to white. Values outside the range are clamped.

This strategy applies sRGB gamma encoding after range mapping.

§Supported pixel types

Same as AutoContrast: single-channel types only.

§Examples

use fovea::pixel::{Mono16, Srgba8};
use fovea_display::{DisplayStrategy, FixedRange};

let fr = FixedRange::new(100.0, 200.0);
assert_eq!(fr.to_display(&Mono16::new(100)), Srgba8::new(0, 0, 0, 255));
assert_eq!(fr.to_display(&Mono16::new(200)), Srgba8::new(255, 255, 255, 255));

// Values outside the range are clamped
assert_eq!(fr.to_display(&Mono16::new(0)), Srgba8::new(0, 0, 0, 255));
assert_eq!(fr.to_display(&Mono16::new(65535)), Srgba8::new(255, 255, 255, 255));

Implementations§

impl FixedRange

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

Create a FixedRange with the given min/max bounds.

Values at min map to black, values at max map to white. If min == max, all pixels map to mid-gray.
