Styling extruded lines in GE

Question

The issue is I need to change the default color and opacity of extruded line's border. Here is an image from GE API.

So, I need to customize the grey 'wall' under the line. How can it be restyled? Thanks.

Answer 1

So, basically the 'border' of an extruded line is a Polygon object and should be styled respectively.

Below is the sample from GE API with one additional line and one new method getPolyStyle(), which adds custom styling to the 'wall':

// Create the placemark
var lineStringPlacemark = ge.createPlacemark('');

// Create the LineString; set it to extend down to the ground
// and set the altitude mode
var lineString = ge.createLineString('');
lineStringPlacemark.setGeometry(lineString);
lineString.setExtrude(true);
lineString.setAltitudeMode(ge.ALTITUDE_RELATIVE_TO_GROUND);

// Add LineString points
lineString.getCoordinates().pushLatLngAlt(48.754, -121.835, 700);
lineString.getCoordinates().pushLatLngAlt(48.764, -121.828, 700);
lineString.getCoordinates().pushLatLngAlt(48.776, -121.818, 700);
lineString.getCoordinates().pushLatLngAlt(48.787, -121.794, 700);
lineString.getCoordinates().pushLatLngAlt(48.781, -121.778, 700);
lineString.getCoordinates().pushLatLngAlt(48.771, -121.766, 700);
lineString.getCoordinates().pushLatLngAlt(48.757, -121.768, 700);
lineString.getCoordinates().pushLatLngAlt(48.747, -121.773, 700);

// Create a style and set width and color of line
lineStringPlacemark.setStyleSelector(ge.createStyle(''));
var lineStyle = lineStringPlacemark.getStyleSelector().getLineStyle();

/*** STYLING THE POLYGON ('WALL') UNDER THE LINE ***/
lineStringPlacemark.getStyleSelector().getPolyStyle().getColor().set('9900ffff');
/***************************************************/

lineStyle.setWidth(5);
lineStyle.getColor().set('9900ffff');  // aabbggrr format

// Add the feature to Earth
ge.getFeatures().appendChild(lineStringPlacemark);
