Struct RawImage 

Source 
pub struct RawImage {
    pub width: u32,
    pub height: u32,
    pub values: Vec<f32>,
    pub default_window: Option<(f64, f64)>,

Expand description

Rescaled monochrome pixel values, ready for interactive windowing.

Produced by load_raw. The modality LUT (rescale slope/intercept) has already been applied — for CT this means Self::values are in Hounsfield Units. VOI windowing is not applied; that happens cheaply on every drag delta via render_rgba.

Images larger than 2048 px per side are decimated at load time; Self::display_scale records the factor so measurements can convert back to original-pixel units.

Fields§

§width: u32

Image width in pixels (after decimation).

§height: u32

Image height in pixels (after decimation).

§values: Vec<f32>

Pixel values, row-major. Length = width * height. Already in modality units (HU on CT).

§default_window: Option<(f64, f64)>

(center, width) from WindowCenter/WindowWidth if present.

§min_val: f32

Minimum finite value in Self::values.

§max_val: f32

Maximum finite value in Self::values.

§photometric_invert: bool

true for MONOCHROME1 — display inversion is needed.

§display_scale: u32

Decimation factor applied at load time. 1 = full resolution. Used to scale measurements back to original-pixel units.
