A technique for graphically processing perimeter information includes determining a polar representation of the perimeter of an object to define polar perimeter information, storing the polar perimeter information, retrieving the stored polar perimeter information using an overlay, and applying the retrieved polar perimeter information to provide a graphical effect within a scene. The anastomosis device may include first flange members and second flange members extending from an open central structure, where at least one second flange member has a free end oriented generally toward at least one first flange member after the anastomosis device has been deployed. In certain embodiments, the elution can have a flow rate of separation of less than 10 minutes to produce an eluted solution comprising isolated nucleic acid. A display format is chosen and the output information is inserted into the selected display format according to the identification information. The system also allows for the easy creation of circles of network friends where content and information can be easily shared. The manuscript conveyer guide is arranged neighboring the contact glass plate on the manuscript discharge side and effectively suppresses the occurrence of unevenness in the reading of the manuscript.
