距离的算子

点：p

线：l

双线：ss

region:　 r

contour:　c

======================================

1.点到点的距离

distance_pp(Row1, Column1, Row2, Column2, Distance)

2.点到线的垂直距离

distance_pl (100, 100, Row1, Column1, Row2, Column2, Distance)

3.线到线的距离

distance_ss (Row11, Column11, Row11, Column11, Row1, Column1, Row2, Column2, DistanceMin, DistanceMax)

DistanceMin：垂直距离（最短距离）

DistanceMax：最长距离（应用在何处)

4.线到region的距离

select_obj (SortedContours, ObjectSelected, Index)
gen_region_contour_xld (ObjectSelected, Region, ‘filled‘)
distance_lr (Region, Row1, Column1, Row2, Column2, DistanceMin, DistanceMax)  //

DistanceMin：垂直距离

5.线到轮廓的距离

distance_lc (SortedContours, Row1, Column1, Row1, Column1, DistanceMin1, DistanceMax1)
