POSITION_NAMES =

Flms provides some ‘friendly’ position values to hide the details of setting x,y values for CSS positioning of layers. Below we store a list of valid position names, and corresponding x,y coordinates for each

%w[center top-left top top-right right bottom-right bottom bottom-left left]
POSITION_COORDINATES = 
[[0.5, 0.5], [0.0, 0.0], [0.5, 0.0], [1.0, 0.0], [1.0, 0.5], [1.0, 1.0], [0.5, 1.0], [0.0, 1.0], [0.0, 0.5]]
