How to fill a selection with a different color while still keep the line color?

[WangPing]

 Dear List,
 
I drew an ROI with red color, now I filled it with a different color (for example green), then I found the red boundary line of the ROI was not shown any more.  I wonder if anyone knows how to keep the line color for the ROI?
Thanks.

Hi Ping Wang,

Use enlarge selection with a negative value. The selection will shrink then. After this fill this selection and the boundary line will be preserved.

Regards,
Peter

Dear Ping Wang,
I'm not sure whether I misunderstood what you are looking for.
But is the feature you are interested not just the Edit->Draw (or Ctrl + D)
feature.
It will draw a line which color is the active one and thickness can be
defined in Edit->Options->Line_width...
My best regards,
Philippe

Dear Philippe,
 
Thank you for your response, but my question is slightly different.  I draw an ROI (for example an oval, or a polygon) it should have a color of its boundary.  Then I fill the ROI with one color (press Y), then the ROI boundary disappears.  My question was how to still display the boundary when the ROI is filled with some color.
 
Best,
Ping

A single selection cannot be filled and have a boundary at the same time, but you can use an overlay as a work around. The following macro creates an overlay containing a blue filled oval with a red boundary and transparent magenta filled polygon with a yellow boundary.

  newImage("Untitled", "8-bit ramp", 512, 512, 1);
  makeOval(86, 70, 162, 116);
  Overlay.addSelection("", 0, "blue");
  makeOval(86, 70, 162, 116);
  Overlay.addSelection("red", 3);
  makePolygon(312,195,187,335,440,387,417,240);
  Overlay.addSelection("", 0, "22ff00ff");
  makePolygon(312,195,187,335,440,387,417,240);
  Overlay.addSelection("yellow", 7);
  run("Select None");

And here is a Javascript version:

  imp = IJ.createImage("Untitled", "8-bit ramp", 512, 512, 1);
  overlay = new Overlay();
  oval1 = new OvalRoi(86, 70, 162, 116);
  oval1.setFillColor(Color.blue);
  overlay.add(oval1);
  oval2 = oval1.clone();
  oval2.setStrokeColor(Color.red);
  oval2.setStrokeWidth(3);
  overlay.add(oval2);
  xpoints = [312,187,440,417];
  ypoints = [195,335,387,240];
  polygon1 = new PolygonRoi(xpoints,ypoints,Roi.POLYGON);
  polygon1.setFillColor(new Color(1,0,1,0.13));
  overlay.add(polygon1);
  polygon2 = polygon1.clone();
  polygon2.setStrokeColor(Color.yellow);
  polygon2.setStrokeWidth(7);
  overlay.add(polygon2);
  imp.setOverlay(overlay);
  imp.show();

Dear Ping,

Please try the following macro:

run("Clown (14K)");

makeOval(149, 58, 69, 44);
setForegroundColor(0, 0, 255);
run("Fill", "slice");
setForegroundColor(70, 255, 0);
run("Draw");
run("Select None");

makePolygon(54,30,85,32,94,41,101,51,99,58,81,58,63,54,60,46);
setForegroundColor(255, 57, 0);
run("Fill", "slice");

run("Select None");
run("Restore Selection");

setForegroundColor(255, 255, 0);
run("Draw");
run("Select None");

It downloads the clown picture,
then draws an oval ROI that is filled with blue and its bondary with green
then it draws a polygonal ROI that is filled with red, its selection deselected and selected again and the ROI boundary drawn in yellow.

Isn't this what you are looking for ?

My best regards,

Philippe
