dimple1.tif	Dimple radius = full-width of the image
dimple2.tif	Dimple radius = 0.75 * full-width of the image	
dimple3.tif	Dimple radius = 0.5  * full-width of the image	
dimple4.tif	Dimple radius = 0.25 * full-width of the image	

dimple_r.tif	A repeating dimple pattern in which every other row is
