Struct ImageSliceStyle 

pub struct ImageSliceStyle {
    pub window_sensitivity: f64,
    pub level_sensitivity: f64,
    pub slice_scroll_step: f64,
    /* private fields */
}

Image-slice interaction style.

Maintains an internal WindowLevel that the consumer can read after each event via ImageSliceStyle::window_level.

Slice scrolling is communicated through a slice_delta value that the consumer should read and apply to its crate::reslice::SlicePlane.

Fields

window_sensitivity: f64

Pixels per unit of window width change (default 4.0).

level_sensitivity: f64

Pixels per unit of window center change (default 2.0).

slice_scroll_step: f64

World units per scroll tick for slicing (default 1.0).

Implementations

impl ImageSliceStyle

pub fn new(window_level: WindowLevel) -> Self

Create with default sensitivities and the given initial window/level.

pub fn window_level(&self) -> WindowLevel

The current window/level (updated by drag events).

pub fn take_slice_delta(&mut self) -> f64

Consume and return the accumulated slice translation since the last call.

The consumer should apply this to its SlicePlane::offset_along_normal.

Trait Implementations
