Description

mmsetrans translates a structuring element by a specific value.

Examples

>>> b1 = mmseline(5)

              
>>> mmseshow(b1)

              
array([0, 0, 0, 0, 1, 1, 1, 1, 1],'1')

              
>>> b2 = mmsetrans(b1,[2,-2])

              

              
>>> mmseshow(b2)
        

              
array([[0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [0, 0, 0, 0, 0],
       [1, 1, 1, 1, 1]],'1')
