Hi!
The following code adds a part of a circle-line (width is 10°) which
is only visible in the direction of a given azimuth. Now I want to
fill the sector (from the central point to the part of circle-line)
with a colour. But this isn't possible yet, because "fill" needs the
complete circle-line (360°). Is there a solution for this problem?
If not, how can I realize a coloured line or more coloured lines
(radius-line) which is/are shown in the direction of the given
azimuth. Such as nodes or beams.
Can you help me please?
function drawDiagramm(point,radius,color,line,image,fill,azi){
var zoom = map.getZoom();
var centerPt = map.fromLatLngToDivPixel(point);
// var radiusPt = map.fromLatLngToDivPixel(rpoint);
var radiusPt = centerPt;
rpt1 = radiusPt.x + radius;
rpt2 = radiusPt.y + radius;
radiusPt = new GPoint(rpt1,rpt2)
var circlePoints = Array();
with (Math) {
radius = floor(sqrt(pow((centerPt.x-radiusPt.x),2) + pow
((centerPt.y-radiusPt.y),2)));
for (var a = -5 ; a < 10 ; a+=5 ) {
var aRad = (azi - 90 - a)*(PI/180);
var y = centerPt.y + radius * sin(aRad);
var x = centerPt.x + radius * cos(aRad);
var p = new GPoint(x,y);
var mypt = map.fromDivPixelToLatLng(p, zoom);
circlePoints.push(mypt);
if(image != "")
{
var mark = createMapMarker(mypt,image);
map.addOverlay(mark);
}
}
if(fill != "")
{
circleLine = new GPolygon(circlePoints,color,line,
0.5,fill,0.5);
}
else
{
circleLine = new GPolygon(circlePoints,color,line,0.8);
}
map.addOverlay(circleLine);
}
