       ann2fig - Dump ANN tree structure in Fig format


           ann2fig [-upi scale] [-x low_x] [-y low_y]
               [-sz size] [-dx dim_x] [-dy dim_y] [-sl dim value]*
               [-ps pointsize] file


       This program inputs an ann dump file of a search structure perhaps
       along with point coordinates, and outputs a fig (Ver 3.1) file (see
       fig2dev (1)) displaying the tree.  The fig file may then be displayed
       using xfig, or converted to any of a number of other formats using

       If the dimension is 2 then the entire tree is displayed.  If the
       dimension is larger than 2 then the user has the option of selecting
       which two dimensions will be displayed, and the slice value for each of
       the remaining dimensions.  All leaf cells intersecting the slice are
       shown along with the points in these cells.


       -upi scale
           fig units per inch (default = 1200)

       -x low_x -y low_y
           x and y offset of upper left corner (inches) (default = 1)

       -sz size
           maximum side length of figure (in inches) (default = 5)

       -dx dim_x
           horizontal dimension (default = 0)

       -dy dim_y
           vertical dimension (default = 1)

       -sv value
           default slice value (default = 0)

       -sl dim value
           each such pair defines the value along the given dimension at which
           to slice.  This may be supplied for all dimensions except dim_x and

       -ps pointsize
           size of points in fig units (def = 10)

           file (input=file.dmp, output=file.fig)
