Property Details

brightness Property brightness Number

Changes the image brightness loaded in the viewer. Brightness is adjusted in the oriented imagery viewer using interactive sliders. Settings will be preserved for subsequent images loaded in the oriented imagery viewer. The value must be between -10 and 10.

contrast Property contrast Number

Changes the image contrast loaded in the viewer. Contrast is adjusted in the oriented imagery viewer using interactive sliders. Settings will be preserved for subsequent images loaded in the oriented imagery viewer. The value must be between -10 and 10.

Default Value:0

currentCoverageVisible Property currentCoverageVisible Boolean

Toggles the visibility of the current footprint polygon associated with the selected image loaded in the viewer. Current footprint coverage allows you to better understand how the images in the oriented imagery layer relate to the map. The footprint of the image is symbolized with red fill on the map. If you zoom or pan in the oriented imagery viewer, the footprint coverage graphic will update on the map to highlight the area on the map that is visible in the image.

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

imageLoaded Property imageLoaded Boolean

Indicates if the image has been loaded onto the oriented imagery viewer.

Default Value:false

isAdditionalCoverageVisible Property isAdditionalCoverageVisible Boolean

Indicates if the additional footprint polygons are visible for the selected image loaded in the viewer. The footprint graphics (appearing in blue) show the coverage footprints of all the additional images in the layer that depict the location selected by the user.

Default Value:false

isAdditionalPointSourcesVisible Property isAdditionalPointSourcesVisible Boolean

Indicates if the additional camera locations are visible for the selected image loaded in the viewer. The point location graphics (appearing in blue) shows the camera locations for additional images that depict the location selected by the user.

layer Property layer OrientedImageryLayer

OrientedImageryLayer associated with the widget. The layer contains feature data and oriented imagery properties required by the viewer to load the image and generate the associated graphics.

mapImageConversionToolState Property mapImageConversionToolState Boolean

Indicates if the map-image location tool available in the widget. When activated, the user can select a point on the map and corresponding a location in pixel space will be displayed in the image, and vice versa.

Default Value:false

sharpness Property sharpness Number

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

Returns true if a named group of handles exist.

Parameter

groupKey *

optional

A group key.

Returns

Type	Description
Boolean	Returns `true` if a named group of handles exist.

Example
