Extrusion Color (Other Than Gray)

[Oraxia]

The extrusion example right here shows a colored line with gray panels
as the extrusion down to Earth:
http://code.google.com/apis/earth/documentation/geometries.html

Is there a way to change the color (and possibly the transparency) of
the gray extrusion panels? Or is opaque gray the only color that comes
in?

[Matthew J Reines]

Yes, although I'm not sure of the color extrusion should take on the
transparency of the Fill.A value.

Okay, I guess I made a blunder with my original question--I should
have asked HOW :/ I probably also should have mentioned that I'm very,
very new to this, which is why I'm asking such lame questions. I
didn't see a fill color attribute on KmlLineStyle, so how would I set
a "fill" color?

[Matthew J Reines]

Here's a (JavaScript) snippet:

//Create a style and set width and color of line
polygonPlacemark.setStyleSelector(ge.createStyle(''));
var lineStyle = polygonPlacemark.getStyleSelector().getLineStyle
();
lineStyle.setWidth(5);
lineStyle.getColor().set('9900ffff');
var polyStyle = polygonPlacemark.getStyleSelector().getPolyStyle
();
polyStyle.setFill(1);
polyStyle.getColor().set('77555555');

When I draw a polygon after setting it up with this code, the
'extruded' color is grey and semi-transparent. I believe this would
also set color if you wanted something other than grey.

Hope that helps.

Polygons have fill, and I've been able to do that, but what if my
extruded line is... just an extruded line? I'm talking about the grey
panels under the line, not some area in the middle of a polygon... Or
am I misreading the code snippet and somehow I can give a line a
KmlPolyStyle? Thanks!

Oraxia,

This code works for both lines and polygons. If the 'polygonPlacemark'
was a 'lineStringPlacemark' the same code will work.

I run this code (snippet) for linestrings and polylines the 'ikp'
variable can either be a polygon or linestring placemark.


ikp.setStyleSelector(_ge.GetPlugin().createStyle(""));
var style = ikp.getStyleSelector() as IKmlStyle;


IKmlLineStyle lineStyle = style.getLineStyle();

if (attributes.BorderStyle == LineStyle.Thick ||
attributes.BorderStyle == LineStyle.Chain ||
attributes.BorderStyle == LineStyle.ZigZag )
{
lineStyle.setWidth(5);
}
else
{
lineStyle.setWidth(2);
}

lineStyle.getColor().setA(attributes.BorderColor.A);
lineStyle.getColor().setR(attributes.BorderColor.R);
lineStyle.getColor().setG(attributes.BorderColor.G);
lineStyle.getColor().setB(attributes.BorderColor.B);

style.getPolyStyle().setFill(1);
style.getPolyStyle().setOutline(1);
style.getPolyStyle().getColor().setA
(attributes.FillColor.A);
style.getPolyStyle().getColor().setR
(attributes.FillColor.R);
style.getPolyStyle().getColor().setG
(attributes.FillColor.G);
style.getPolyStyle().getColor().setB
(attributes.FillColor.B);

Thank you!
