A module used to change the information of user action entered by various input devices such as touch screen or mouse into the logical virtual coordinates. You can easily create a UI that responds to user actions.

import { ElementType } from "../types";
import { InputType, InputTypeObserver } from "./InputType";
export interface PinchInputOption {
    scale?: number;
    threshold?: number;
    inputType?: string[];
    touchAction?: string;
}
export declare class PinchInput implements InputType {
    options: PinchInputOption;
    axes: string[];
    element: HTMLElement;
    private _observer;
    private _pinchFlag;
    private _enabled;
    private _originalCssProps;
    private _activeEvent;
    private _baseValue;
    private _isOverThreshold;
    constructor(el: ElementType, options?: PinchInputOption);
    mapAxes(axes: string[]): void;
    connect(observer: InputTypeObserver): InputType;
    disconnect(): this;
    destroy(): void;
    enable(): this;
    disable(): this;
    isEnabled(): boolean;
    private _onPinchStart;
    private _onPinchMove;
    private _onPinchEnd;
    private _attachEvent;
    private _detachEvent;
