# Configuration

Angles definitions

Photo Sphere Viewer uses a lot of angles for its configuration, most of them can be defined in radians by using a simple number (3.5) or in degrees using the "deg" prefix ('55deg').

Positions defintions

Some methods take a position parameter. It is an object with either longitude and latitude properties (radians or degrees) or x and y properies (corresponding to the pixel position on the source panorama file).

# Standard options

# container (required)

  • type: HTMLElement | string

HTML element which will contain the panorama, or identifier of the element.

container: document.querySelector('.viewer')

container: 'viewer' // will target [id="viewer"]

# panorama (required)

  • type: string | string[] | object

Path to the panorama image(s). It must be a single string for equirectangular panoramas and an array or an object for cubemaps.

// Equirectangular panorama :
panorama: 'path/to/panorama.jpg'

// Cubemap as array (order is important) :
panorama: [
  'path/to/left.jpg', 'path/to/front.jpg',
  'path/to/right.jpg', 'path/to/back.jpg',
  'path/to/top.jpg', 'path/to/bottom.jpg',

// Cubemap as object :
panorama: {
  left:   'path/to/left.jpg',  front:  'path/to/front.jpg',
  right:  'path/to/right.jpg', back:   'path/to/back.jpg',
  top:    'path/to/top.jpg',   bottom: 'path/to/bottom.jpg',

# plugins

# fisheye

  • type: boolean | double
  • default: false

Enable fisheye effect with true or specify effect strength (true = 1.0).


This mode can have side-effects on markers rendering.

# defaultLong

  • type: double | string
  • default: 0

Initial longitude, between 0 and 2π.

# defaultLat

  • type: double | string
  • default: 0

Initial latitude, between -π/2 and π/2.

# longitudeRange

Now part of a plugin.

# latitudeRange

Now part of a plugin.

# autorotateDelay

  • type: integer
  • default: null

Delay after which the automatic rotation will begin, in milliseconds.

# autorotateSpeed

  • type: string
  • default: 2rpm

Speed of the automatic rotation.

# autorotateLat

  • type: double | string
  • default: defaultLat

Latitude at which the automatic rotation is performed.

# lang

  • type: object
  • default:
lang: {
    autorotate: 'Automatic rotation',
    zoom      : 'Zoom',
    zoomOut   : 'Zoom out',
    zoomIn    : 'Zoom in',
    download  : 'Download',
    fullscreen: 'Fullscreen',
    menu      : 'Menu',
    twoFingers: 'Use two fingers to navigate',
    ctrlZoom  : 'Use ctrl + scroll to zoom the image',
    loadError : 'The panorama can\'t be loaded',

Various texts used in the viewer.

# loadingImg

  • type: string

Path to an image displayed in the center of the loading circle.

# loadingTxt

  • type: string
  • default: 'Loading...'

Text displayed in the center of the loading circle, only used if loadingImg is not provided.

# mousewheel

  • type: boolean
  • default: true

Enables zoom with the mouse wheel.

# mousemove

  • type: boolean
  • default: true

Enables panorama rotation with the mouse cursor or with a finger swipe on touch screens.

# mousewheelCtrlKey

  • type: boolean
  • default: false

Requires to use the ctrl key to zoom the panorama. The allows to scroll the page without interfering with the viewer. If enabled, an overlay asking the user to use ctrl + scroll is displayed when ctrl key is not pressed.

  • type: boolean
  • default: false

Rotate the panorama just by moving the cursor above the view instead of click+move.

# touchmoveTwoFingers

  • type: boolean
  • default: false

Requires two fingers to rotate the panorama. This allows standard touch-scroll navigation in the page containing the viewer. If enabled, an overlay asking the user to use two fingers is displayed when only one touch is detected.

# Advanced options

# sphereCorrection

  • default: { pan:0, tilt:0, roll: 0 }

Sphere rotation angles, in radians.


# moveSpeed

  • type: double

# useXmpData

  fullHeight: 3000,
  croppedWidth: 4000,
  croppedHeight: 2000,
  croppedX: 1000,
  croppedY: 500

It can also be a function to dynamically compute the cropping config depending on the loaded image.

panoData: (image) => ({

  fullHeight   : image.width / 2,
  croppedWidth : image.width,
  croppedHeight: image.height,
