 // all vector layers except the Panoramas layer
ALLVECTOREXCEPTPANORAMASPOINTSLINES: 'allvectorexceptpanoramaspointslines' // The 
 // function will include all vector layers, but for a Panoramas layer
 // it will include only

ViewerOptions

Options for bu.ortho.Viewer.

Type:

• Object

Properties:

Name	Type	Description
target	Element | string | undefined	The DOM target element where this viewer will be appended.
center	bu.Coordinate | undefined	The initial center for the view. The coordinate system for the center is always an EPSG:4326 LanLot.
constrainRotation	boolean | number | undefined	Rotation constraint. false means no constraint. true means no constraint, but snap to zero near zero. A number constrains the rotation to that number of values. For example, 4 will constrain the rotation to 0, 90, 180, and 270 degrees. The default is true.
enableRotation	boolean | undefined	Enable rotation. Default is true. If false a rotation constraint that always sets the rotation to zero is used. The constrainRotation option has no effect if enableRotation is false.
extent	bu.Extent | undefined	The extent that constrains the center, in other words, center cannot be set outside this extent. Default is undefined.
maxResolution	number | undefined	The maximum resolution used to determine the resolution constraint. It is used together with minResolution (or maxZoom) and zoomFactor. If unspecified it is calculated in such a way that the projection's validity extent fits in a 256x256 px tile. If the projection is Spherical Mercator (the default) then maxResolution defaults to 40075016.68557849 / 256 = 156543.03392804097.
minResolution	number | undefined	The minimum resolution used to determine the resolution constraint. It is used together with maxResolution (or minZoom) and zoomFactor. If unspecified it is calculated assuming 29 zoom levels (with a factor of 2). If the projection is Spherical Mercator (the default) then minResolution defaults to 40075016.68557849 / 256 / Math.pow(2, 28) = 0.0005831682455839253.
maxZoom	number | undefined	The maximum zoom level used to determine the resolution constraint. It is used together with minZoom (or maxResolution) and zoomFactor. Default is 28. Note that if minResolution is also provided, it is given precedence over maxZoom.
minZoom	number | undefined	The minimum zoom level used to determine the resolution constraint. It is used together with maxZoom (or minResolution) and zoomFactor. Default is 0. Note that if maxResolution is also provided, it is given precedence over minZoom.
projection	string | undefined	The projection. Default is EPSG:3857 (Spherical Mercator).
resolution	number | undefined	The initial resolution for the view. The units are projection units per pixel (e.g. meters per pixel). An alternative to setting this is to set zoom. Default is undefined, and layer sources will not be fetched if neither this nor zoom are defined.
resolutions	Array.<number> | undefined	Resolutions to determine the resolution constraint. If set the maxResolution, minResolution, minZoom, maxZoom, and zoomFactor options are ignored.
rotation	number | undefined	The initial rotation for the view in radians (positive rotation clockwise). Default is 0.
zoom	number | undefined	Only used if resolution is not defined. Zoom level used to calculate the initial resolution for the view. The initial resolution is determined using the ol.View#constrainResolution method.
zoomFactor	number | undefined	The zoom factor used to determine the resolution constraint. Default is 2.
layers	Array.<Object> | undefined	Layers. If this is not defined, a map with no layers will be rendered. Note that layers are rendered in the order supplied, so if you want, for example, a vector layer to appear on top of a tile layer, it must come after the tile layer.
