An overlay can be activated as a selection by Alt-clicking on it.
In Java, one way to achieve this would be:

Roi[] ovlArray = imp.getOverlay().toArray();
for (Roi roi: ovlArray) {
     imp.setRoi(roi);
     IJ.run(imp, "Draw", "slice");
}

You can use

     imp.flattenStack();

to flatten the image stack in-place.
See the javadoc here:

Hope that helps,
