Struct MagnifierParams 

#[repr(C)]
pub struct MagnifierParams {
    pub center_x: f32,
    pub center_y: f32,
    pub radius: f32,
    pub magnification: f32,
}

Parameters for magnifier. Default is a lens in the frame center; move it live via the params handle to sweep it around.

Inside radius the sampling coordinates contract toward the lens center by a factor that eases (smoothstep) from magnification at the center to 1 at the rim — a convex lens without a hard edge. Outside the radius the image is untouched.

Fields

center_x: f32

Lens center x as a fraction of the width, 0.0..=1.0.

center_y: f32

Lens center y as a fraction of the height, 0.0..=1.0.

radius: f32

Lens radius as a fraction of the frame height, 0.0..=1.0. The lens is physically round regardless of aspect.

magnification: f32

Peak zoom at the lens center, 1.0..=5.0.
