A single ROI cannot be both filled and outlined. You need to use two, one filled and the other outlined. Here is a macro example:
newImage("Untitled", "8-bit black", 400, 400, 1);
makePolygon(230,70,325,260,55,300);
run("Fit Spline");
run("Properties... ", " fill=green");
run("Add Selection...");
run("Select None");
run("Restore Selection");
run("Properties... ", "stroke=red width=9");
run("Add Selection...");
run("Select None”);
And here is a JavaScript example:
img = IJ.createImage("Untitled", "8-bit black", 400, 400, 1);
xpoints = [230, 325, 55];
ypoints = [70, 260, 300];
roi1 = new PolygonRoi(xpoints, ypoints, Roi.POLYGON);
roi1.fitSpline();
roi1.setFillColor(Color.green);
overlay = new Overlay();
overlay.add(roi1);
roi2 = roi1.clone();
roi2.setStrokeColor(Color.red);
roi2.setStrokeWidth(9);
overlay.add(roi2);
img.setOverlay(overlay);
img.show();
