I am trying to get my head around "Displacement Maps" (photoshop cs2) I have looked at quite a few tutorials but have not found any that explain the "Filter-Distort-Displace" settings, eg when to use stretch to fit or tile under "Displacement Map" or wrap around or repeat edge pixels under "Underfined Areas" or how to determine what numbers to put in the "Horizontal Scale" and "Vertical Scale" boxes.
