Determines equality based soley on the projection code. 121 122 *Returns* 123 124 ``{Boolean}`` The two projections are equivalent. 84 125 85 126 .. _destroy: 86 127 87 128 destroy 88 Destroy projection object. 129 :: 130 131 destroy: function() 132 133 Destroy projection object. 89 134 90 135 .. _transform: 91 136 92 137 transform 93 Transform a point coordinate from one projection to another. 138 :: 139 140 ZOO.Projection.transform = function(point,source,dest) 141 142 Transform a point coordinate from one projection to another. Note that the input point is 143 transformed in place. 144 145 *Parameters* 146 147  ``point {{ZOO.Geometry.Point>  Object}`` An object with x and y properties representing coordinates in those dimensions. 148  ``sourceProj {ZOO.Projection}`` Source map coordinate system 149  ``destProj {ZOO.Projection}`` Destination map coordinate system 150 151 *Returns* 152 153 ``point {object}`` A transformed coordinate. The original point is modified.
