sint NLPACS::CEdgeQuad::selectEdges (  CVector    start,

)  const
 

look in the quad to select a list of chain from a line.

NB: The outpout do not contains any redundant edge. An edge appears only one time in the result.

Parameters:
start  the starting point of the selection segment.
end  the ending point of the selection segment.
cst  the array of CExteriorEdgeEntry to fill. contain also OChainLUT, an array for internal use. In: must be filled with 0xFFFF. Out: still filled with 0xFFFF.
Returns:
number of exterioredge found. stored in cst.ExteriorEdgeEntries (array cleared first).

look in the quad to select a list of chain from a bbox.

NB: The outpout do not contains any redundant edge. An edge appears only one time in the result.

Parameters:
bbox  the area of interest.
cst  the array of CExteriorEdgeEntry to fill. contain also OChainLUT, an array for internal use. In: must be filled with 0xFFFF. Out: still filled with 0xFFFF.
Returns:
number of exterioredge found. stored in cst.ExteriorEdgeEntries (array cleared first).
