geometryService.buffer with "sqaure ends"?

[JamesCrandall]

Hi all,

I'm successfully generating buffered polygons for input polyline features and the requirement has changed to show "square ends" rather than the rounded ends the current buffer is creating.  

Is there a simple parameter I'm missing for the BufferParameters() of a call to the geometryService.Buffer()?

Thanks for any input!

//populate the polyline geometries
var features = layer.featureSet.features;
arrayUtils.forEach(features, lang.hitch(this, function (feature) {
 this.shapeGeometries.push(new Polyline(feature.geometry));
}));

////setup the buffer parameters
var params = new BufferParameters();
params.distances = [buffDist]
params.outSpatialReference = map.spatialReference;
params.bufferSpatialReference = new esri.SpatialReference({ "wkid": "102258" }); //spatial reference info https://spatialreference.org/ref/esri/nad-1983-harn-stateplane-florida-east-fips-0901/
params.unit = GeometryService["UNIT_METER"]; 
params.geometries = this.shapeGeometries;
esriConfig.defaults.geometryService.buffer(params, showBuffer);

//show bufferedGeometries and then continue processing to union them
function showBuffer(bufferedGeometries) {
	 var symbol = new SimpleFillSymbol(
	 SimpleFillSymbol.STYLE_SOLID,
	 new SimpleLineSymbol(
		 SimpleLineSymbol.STYLE_SOLID,
		 new Color([255, 0, 0, 0.65]), 2
	 ),
	 new Color([255, 0, 0, 0.35])
	 );

	 var bFeatures = [];
	 
	 array.forEach(bufferedGeometries, function (geometry) {
		 var graphic = new Graphic(geometry, symbol);			                     
		 bFeatures.push(graphic)			                     
	 });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

James,

   There is not a square end parameter for buffering, so you are not missing anything.
