I’m looking to create one buffer around multiple graphics.
The user clicks the desired polygons, which creates graphics matching the geometry of the polygons. After certain ones are picked I want to buffer around all of those with the same shape they all have together. Below is the code I’m trying for the buffer.
It always break on gsvc.buffer(params, showBuffer); which makes me think there’s a problem with the params.
var geom = new Graphic();
geom = graphicsLayer.graphics;
var selectedGeom = graphicsUtils.getGeometries(geom);
var bufferDist = Math.floor(dom.byId("txtBufferDist").value);
var params = new BufferParameters();
params.geometries = [selectedGeom];
params.distances = [bufferDist];
params.unit = GeometryService.UNIT_FOOT;
params.outSpatialReference = bcMap.spatialReference;
HOWEVER, if I use graphicsUtils.graphicsExtent instead of graphicsUtils.getGeometries it works. But I don’t want a square every time. I want the buffer to follow the outline shape as seen in yellow.
Thanks for any help.
