GPLS can translate layout to stick diagram, stick diagram to layout, layout to layout, mixed input to layout. To achieve these goals, the input format should accept both layout and stick diagram.

A new algorithm for area updating of the corner stitch data structure is presented using non-recursive area enumeration.
