"burning" ROI boundary onto an image

[Ben.BigHair]

Hello,

I would like to "burn" an ROI onto an image, and then save the image,
using ImageJ's (amazing) macro language. The macro below can get pretty
close... but not quite what I am looking for. I would like to have just
the boundary drawn in the final image.  Wayne discussed something like
this in January of this year (see discussion pasted waay below).
Despite his perfectly good advice, I blithely decided to tackle this
differently by changing the pixel values in the RGB image.  The only
trouble is that the interior of the polygon is filled rather than just
the boundary.

Is there a solution short of the "capture-and-crop" approach suggested
by Wayne.

Thanks!
Ben

//BEGIN
run("Blobs (25K)");
run("Duplicate...", "title=blobs-1.gif");
selectWindow("blobs.gif");
setAutoThreshold();
//run("Threshold...");
doWand(86, 76);
selectWindow("blobs-1.gif");
run("RGB Color");
run("Restore Selection");

//the following appears to have no effect
//getSelectionCoordinates(xc,yc);
//for (i=0;i<xc.length;i++){setPixel(xc[i],yc[i],0x00ffff);}

//the following fills the polygon interior
changeValues(0x000000, 0xffffff, 0xffff00);

saveAs("Jpeg", "RGB.jpg");
//END

To highlight in color, you must first convert the image to RGB (Image>Type>RGB Color) and select a color by double clicking on the eye dropper tool. Another way would be to capture the screen by pressing shift-g (Plugins>Utilities>Capture Screen), select the image, and crop. In ImageJ 1.38h or later, you will be able to crop by pressing shift-x, the keyboard shortcut for the Image>Crop command.

Hi Ben,

what about
  setForegroundColor(255, 0, 0); //or whatever color you like
  run("Draw");                   //draws the outline
