optional
Object with the following properties:

Members
backgroundColor : Property
Gets or sets the Property specifying the background
Color
.
-
Default Value:
new Color(0.165, 0.165, 0.165, 0.8)
backgroundPadding : Property
Gets or sets the
Cartesian2
Property specifying the label's horizontal and vertical
background padding in pixels.
-
Default Value:
new Cartesian2(7, 5)
readonlydefinitionChanged : Event
Gets the event that is raised whenever a property or sub-property is changed or modified.
disableDepthTestDistance : Property
Gets or sets the distance from the camera at which to disable the depth test to, for example, prevent clipping against terrain.
When set to zero, the depth test is always applied. When set to Number.POSITIVE_INFINITY, the depth test is never applied.
distanceDisplayCondition : Property
Gets or sets the
DistanceDisplayCondition
Property specifying at what distance from the camera that this label will be displayed.
eyeOffset : Property
Gets or sets the
Cartesian3
Property specifying the label's offset in eye coordinates.
Eye coordinates is a left-handed coordinate system, where x
points towards the viewer's
right, y
points up, and z
points into the screen.
An eye offset is commonly used to arrange multiple labels or objects at the same position, e.g., to arrange a label above its corresponding 3D model.
Below, the label is positioned at the center of the Earth but an eye offset makes it always appear on top of the Earth regardless of the viewer's or Earth's orientation.

l.eyeOffset = new Cartesian3(0.0, 8000000.0, 0.0);
-
Default Value:
Cartesian3.ZERO
fillColor : Property
Gets or sets the Property specifying the fill
Color
.
Gets or sets the string Property specifying the font in CSS syntax.
See:
heightReference : Property
Gets or sets the Property specifying the
HeightReference
.
-
Default Value:
HeightReference.NONE
horizontalOrigin : Property
Gets or sets the Property specifying the
HorizontalOrigin
.
outlineColor : Property
Gets or sets the Property specifying the outline
Color
.
outlineWidth : Property
Gets or sets the numeric Property specifying the outline width.
pixelOffset : Property
Gets or sets the
The label's origin is indicated by the yellow point.
Cartesian2
Property specifying the label's pixel offset in screen space
from the origin of this label. This is commonly used to align multiple labels and labels at
the same position, e.g., an image and text. The screen space origin is the top, left corner of the
canvas; x
increases from left to right, and y
increases from top to bottom.

Default Value:
Cartesian2.ZERO
pixelOffsetScaleByDistance : Property
Gets or sets
NearFarScalar
Property specifying the pixel offset of the label based on the distance from the camera.
A label's pixel offset will interpolate between the NearFarScalar#nearValue
and
NearFarScalar#farValue
while the camera distance falls within the upper and lower bounds
of the specified NearFarScalar#near
and NearFarScalar#far
.
Outside of these ranges the label's pixel offset remains clamped to the nearest bound.
Gets or sets the numeric Property specifying the uniform scale to apply to the image.
A scale greater than
![](Images/Label.setScale.png)
From left to right in the above image, the scales are
1.0
enlarges the label while a scale less than 1.0
shrinks it.
![](Images/Label.setScale.png)
From left to right in the above image, the scales are
0.5
, 1.0
,
and 2.0
.
-
Default Value:
1.0
scaleByDistance : Property
Gets or sets near and far scaling properties of a Label based on the label's distance from the camera.
A label's scale will interpolate between the
NearFarScalar#nearValue
and
NearFarScalar#farValue
while the camera distance falls within the upper and lower bounds
of the specified NearFarScalar#near
and NearFarScalar#far
.
Outside of these ranges the label's scale remains clamped to the nearest bound. If undefined,
scaleByDistance will be disabled.
Gets or sets the boolean Property specifying the visibility of the label.
showBackground : Property
Gets or sets the boolean Property specifying the visibility of the background behind the label.
-
Default Value:
false
Gets or sets the Property specifying the
LabelStyle
.
Gets or sets the string Property specifying the text of the label.
Explicit newlines '\n' are supported.
translucencyByDistance : Property
Gets or sets
NearFarScalar
Property specifying the translucency of the label based on the distance from the camera.
A label's translucency will interpolate between the NearFarScalar#nearValue
and
NearFarScalar#farValue
while the camera distance falls within the upper and lower bounds
of the specified NearFarScalar#near
and NearFarScalar#far
.
Outside of these ranges the label's translucency remains clamped to the nearest bound.
verticalOrigin : Property
Gets or sets the Property specifying the
VerticalOrigin
.
