chaining tolerance

[Duckman]

in the CHOOK API's CHAIN structure, there are two boolean members, "closed" and "branch", which flags if a particular chain is closed, and has branches. The variable that seems to define what a "branch" and what consists of "open" seems to be nc_tol, and this sets the "chaining tolerence" in screen->configure. From my work, it seems that this tolereence is coupled to both the minimum length of an ent to be considered a branch and the "openness" of a chain (ie, the minimum distance between two endpoints to be considered that two entities are not "connected") thus, if this variable is set to a higher number, a more chains would be considered "closed", but also increases the likliehood of a branch being detected. I would like have it so that open chains are not detected, and branches are also not detected...is there a way to do this? or do I not make any sense at all?

 

Thanks!
