pixColorMorph()

Parameters

[in]	pixs
[in]	type	L_MORPH_DILATE, L_MORPH_ERODE, L_MORPH_OPEN, or L_MORPH_CLOSE
[in]	hsize	width of Sel; must be odd; origin implicitly in center
[in]	vsize	ditto for height of Sel

Returns

pixd

Notes:
     (1) This does the morph operation on each component separately,
         and recombines the result.
     (2) Sel is a brick with all elements being hits.
     (3) If hsize = vsize = 1, just returns a copy.
