Set mean gray value (from 16 bit TIFF) as background color

[mmettlen]

My macro measures the mean gray value of 16-bit TIF images but I haven't
figured out how to convert this value (e.g. 130) to use in
setBackgroundColor(R, G, B).... Like always: thanks for helping!

Use setColor(mean), as in this example which fills the center of a 16-bit image with the mean pixel value:

  newImage("Untitled", "16-bit ramp", 500, 500, 1);
  getRawStatistics(nPixels, mean);
  makeOval(125, 125, 250, 250);
  setColor(mean);
  fill;
  run("Select None”);
