Struct EuvPinch 

pub struct EuvPinch {
    pub distance: f64,
    pub start_distance: f64,
    pub center_x: f64,
    pub center_y: f64,
    pub delta: f64,
}

A two-finger pinch described by the distance and midpoint of the two touch points.

The pair is emitted on every touchmove while exactly two fingers are down, so consumers can drive a continuous zoom rather than reacting to a discrete end-of-gesture event.

Fields

distance: f64

Distance in CSS pixels between the two touch points.

start_distance: f64

Distance in CSS pixels when the pinch started, or the previous distance when continuing an in-progress pinch.

center_x: f64

Midpoint X in client coordinates.

center_y: f64

Midpoint Y in client coordinates.

delta: f64

Change in distance since start_distance.

Positive values mean the fingers spread apart (zoom in), negative values mean they moved together (zoom out).
