mode of the contour retrieval algorithm

Variants

RETR_EXTERNAL

retrieves only the extreme outer contours. It sets hierarchy[i][2]=hierarchy[i][3]=-1 for all the contours.

RETR_LIST

retrieves all of the contours without establishing any hierarchical relationships.

RETR_CCOMP

retrieves all of the contours and organizes them into a two-level hierarchy. At the top level, there are external boundaries of the components. At the second level, there are boundaries of the holes. If there is another contour inside a hole of a connected component, it is still put at the top level.

RETR_TREE

retrieves all of the contours and reconstructs a full hierarchy of nested contours.

RETR_FLOODFILL
