pixelOffsetScaleByDistance

Gets or sets near and far pixel offset scaling properties of a Label based on the Label's distance from the camera. A label's pixel offset will be scaled between the NearFarScalar.nearValue and NearFarScalar.farValue while the camera distance falls within the lower and upper bounds of the specified NearFarScalar.near and NearFarScalar.far. Outside of these ranges the label's pixel offset scaling remains clamped to the nearest bound. If undefined, pixelOffsetScaleByDistance will be disabled.

// Example 1.
// Set a label's pixel offset scale to 0.0 when the
// camera is 1500 meters from the label and scale pixel offset to 10.0 pixels
// in the y direction the camera distance approaches 8.0e6 meters.
text.pixelOffset = new Cartesian2(0.0, 1.0);
text.pixelOffsetScaleByDistance = new NearFarScalar(1.5e2, 0.0, 8.0e6, 10.0);

// Example 2.
// disable pixel offset by distance
text.pixelOffsetScaleByDistance = undefined;
