How does one put a contour of a second image on top of the displayed image?
(5/13/92)
Use XRAY.XPLOT.xdisplay (or IMAGES.TV.display) with fill = yes to display the image. Use PLOT.contour on the second image (the one to be overlayed), again with fill = yes. The contour plot will appear on top of the image if the 'device' parameter is set to imdx, with x = g (for Green), r (for Red), b (Blue), y (Yellow), or W (white). The 'fill' parameter is necessary to prevent display / graph borders from affecting the size of the result.
Use with caution, in case the images you are overlaying are not co-centered (use imshift to recenter).
