user prompt to draw oval

Peter Oslanec-2
Hi all,

I am trying to creeate little script to prompt user to draw oval in a
picture.

setTool("oval");
waitForUser("....");

 if (selectionType==-1)
      exit("Area selection required");
  List.setMeasurements;
  //print(List.getList); // list all measurements
  x = List.getValue("X");
  y = List.getValue("Y");
  width = List.getValue("Major");
  heigth = List.getValue("Minor");
makeOval(x,y,width,heigth);

The macro works, but the drawn oval moves its center slightly  to the right
bottom corner of the picture.

Thank you!

Good day Peter,

I've no idea what the macro is intended to perform.

If you should like to permanently draw the elliptical selection (in
white) you could use:

//
setForegroundColor(255, 255, 255); // white
run("Draw", "slice");
run("Select None");
//

You may use the Recorder feature to construct basic macros.

Best

Herbie

Hi Peter,
The List.getValue("X") and List.getValue("Y") are returning the centroid
whereas the makeOval uses the upper left of the bounding rectangle for
positioning.

You can fix it by using List.getValue("BX") and List.getValue("BY") or use
something like getSelectionBounds(x,y,w,h) to get the position of the oval.

George
