geometryService.buffer with "sqaure ends"?

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.
