Default Value: new Color(0.165, 0.165, 0.165, 0.8)

Default Value: new Cartesian2(7, 5)

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

See:

• CSS font on MDN

Default Value: HeightReference.NONE

Gets or sets the 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

l.pixeloffset = new Cartesian2(25, 75);

The label's origin is indicated by the yellow point.

Default Value: Cartesian2.ZERO

Gets or sets the numeric Property specifying the uniform scale to apply to the image. A scale greater than 1.0 enlarges the label while a scale less than 1.0 shrinks it.

From left to right in the above image, the scales are 0.5, 1.0, and 2.0.

Default Value: 1.0

Default Value: false
