An information processing apparatus extracts a plurality of strokes from a multilevel image, and generates a stroke binary image. The method includes providing a substrate. The method includes the steps of receiving a PCN that identifies the change, determining whether the PCN satisfies the implementation requirements, and if the PCN does satisfy these requirements, implementing the change. A mechanism is provided for flipping the seeds so as to enable the imaging subsystem to obtain multi-side seed images. 1,2 and 3 has a multiplicity of air apertures 14A-16A18A, thru, 14F-16F-18F of FIG.
