flst_boundary Find boundary of shape
flst_boundary tree shape boundary
tree : The tree of shapes
shape : The shape whose boundary is to be computed
boundary : boundary computed (output Flist)
Flist flst_boundary (pTree , pShape , pBoundary )
Shapes pTree ;
Shape pShape ;
Flist pBoundary ;
This fills the field boundary of a Shape issued from a tree (see flst_boundary). It is a list of 2-D points with integral coordinates. The last point is equal to the first one if the shape is closed. If the shape is open, the two extremal points are at the border of the image. The shape is followed in counterclockwise direction, so that the shape is on left hand side and the exterior on right hand side.
