By "in use", we means dimension with more than 1 pixel. For example a grid size of 512×512×1 pixels can be represented by this class (some peoples said 2.5D) because a two-dimensional grid coordinate is enough for referencing a pixel without ambiguity. But a grid size of 512×512×2 pixels can not be represented by this , because a three-dimensional coordinate is mandatory for referencing a pixel without ambiguity.<P><P><DL><DT><B>Since:</B></DT>
