type (optional): string

This specifies the panorama type. Can be equirectangular, cubemap, or multires. Defaults to equirectangular.

imageSource (optional): string

Will required when type is equirectangular

Path of image you want to display. Sets the URL to the equirectangular panorama image. This is relative to basePath if it is set, else it is relative to the location of pannellum.htm. An absolute URL can also be used.

equirectangularOptions (optional): object

For equirectangular type only.

haov (number)

Sets the panorama’s horizontal angle of view, in degrees. Defaults to 360. This is used if the equirectangular image does not cover a full 360 degrees in the horizontal.

vaov (number)

Sets the panorama’s vertical angle of view, in degrees. Defaults to 180. This is used if the equirectangular image does not cover a full 180 degrees in the vertical.

vOffset (number)

Sets the vertical offset of the center of the equirectangular image from the horizon, in degrees. Defaults to 0. This is used if vaov is less than 180 and the equirectangular image is not cropped symmetrically.

ignoreGPanoXMP (boolean)

If set to true, any embedded Photo Sphere XMP data will be ignored; else, said data will override any existing settings. Defaults to false.

cubeMap (optional - specific options): array

This is an array of URLs for the six cube faces in the order front, right, back, left, up, down. These are relative to basePath if it is set, else they are relative to the location of pannellum.htm. Absolute URLs can also be used. Partial cubemap images may be specified by giving null instead of a URL.

path (string)

This is a format string for the location of the multiresolution tiles, relative to multiRes.basePath, which is relative to basePath. Format parameters are %l for the zoom level, %s for the cube face, %x for the x index, and %y for the y index. For each tile, .extension is appended.

fallbackPath (string)

This is a format string for the location of the fallback tiles for the CSS 3D transform-based renderer if the WebGL renderer is not supported, relative to multiRes.basePath, which is relative to basePath. The only format parameter is %s, for the cube face. For each face, .extension is appended.

When set to false, the minHfov parameter is ignored for multires panoramas; an automatically calculated minimum horizontal field of view is used instead. Defaults to false.

hfov (optional): number

Sets the panorama’s starting horizontal field of view in degrees. Defaults to 100.

compass (optional): boolean

If true, a compass is displayed. Normally defaults to false.

northOffset (optional): number

Set the offset, in degrees, of the center of the panorama from North. As this affects the compass, it only has an effect if compass is set to true. Default to 0

escapeHTML (optional): boolean

When true, HTML is escaped from configuration strings to help mitigate possible DOM XSS attacks. This is always true when using the standalone viewer since the configuration is provided via the URL; it defaults to false but can be set to true when using the API.

hotSpots (optional): array

This specifies a dictionary of hot spots that can be links to other scenes, information, or external links. Each array element has the following properties:

pitch (number)

Specifies the pitch portion of the hot spot’s location, in degrees.

yaw (number)

Specifies the yaw portion of the hot spot’s location, in degrees.

type (string)

Specifies the type of the hot spot. Can be scene for scene links or info for information hot spots. A tour configuration file is required for scene hot spots.

text (string)

This specifies the text that is displayed when the user hovers over the hot spot.

URL (string)

If specified for an info hot spot, the hot spot links to the specified URL. Not applicable for scene hot spots.

sceneId (string)

Specifies the ID of the scene to link to for scene hot spots. Not applicable for info hot spots.

targetPitch (number)

Specifies the pitch of the target scene, in degrees. Can also be set to same, which uses the current pitch of the current scene as the initial pitch of the target scene.

targetYaw (number)

Specifies the yaw of the target scene, in degrees. Can also be set to same or sameAzimuth. These settings use the current yaw of the current scene as the initial yaw of the target scene; same uses the current yaw directly, while sameAzimuth takes into account the northOffset values of both scenes to maintain the same direction with regard to north.

targetHfov (number)

Specifies the HFOV of the target scene, in degrees.

id

Specifies hot spot ID, for use with API’s removeHotSpot function.

cssClass (string)

If specified, string is used as the CSS class for the hot spot instead of the default CSS classes.

createTooltipFunc (function) and createTooltipArgs (object)

If createTooltipFunc is specified, this function is used to create the hot spot tooltip DOM instead of the default function. The contents of createTooltipArgs are passed to the function as arguments.

clickHandlerFunc (function) and clickHandlerArgs (object)

If clickHandlerFunc is specified, this function is added as an event handler for the hot spot’s click event. The event object and the contents of clickHandlerArgs are passed to the function as arguments.

hotSpotDebug (optional): boolean

When true, the mouse pointer’s pitch and yaw are logged to the console when the mouse button is clicked. Defaults to false.

sceneFadeDuration (optional): number

Specifies the fade duration, in milliseconds, when transitioning between scenes. Not defined by default. Only applicable for tours. Only works with WebGL renderer.

capturedKeyNumbers (optional): array

Specifies the key numbers that are captured in key events. Defaults to the standard keys that are used by the viewer.

backgroundColor (optional): [number, number, number]

Specifies an array containing RGB values [0, 1] that sets the background color for areas where no image data is available. Defaults to [0, 0, 0] (black). For partial equirectangular panoramas this applies to areas past the edges of the defined rectangle. For multires and cubemap (including fallback) panoramas this applies to areas corresponding to missing tiles or faces.

avoidShowingBackground (optional): boolean

If set to true, prevent displaying out-of-range areas of a partial panorama by constraining the yaw and the field-of-view. Even at the corners and edges of the canvas only areas actually belonging to the image (i.e., within [minYaw, maxYaw] and [minPitch, maxPitch]) are shown, thus setting the backgroundColor option is not needed if this option is set. Defaults to false.
