[mmsedisk] [Up] [mmserot] Structuring Elements

mmseline
Create a line structuring element.

Synopsis

B = mmseline ( l = 3, theta = 0 )

Input

l Double Non-negative integer.

Default: 3 (3)
theta Double

(degrees, clockwise)

Default: 0 (0)

Output

B Structuring Element

Description

mmseline creates a structuring element B that is a line segment that has an extremity at the origin, length l and angle theta (0 degrees is east direction, clockwise). If l=0, it generates the origin.

Examples

mmseshow(mmseline())
array([False, False,  True,  True,  True], dtype=bool)
b1 = mmseline(4,45)
mmseshow(b1)
array([[False, False, False, False, False],
       [False, False, False, False, False],
       [False, False,  True, False, False],
       [False, False, False,  True, False],
       [False, False, False, False,  True]], dtype=bool)
b2 = mmseline(4,-180)
mmseshow(b2)
array([ True,  True,  True,  True, False, False, False], dtype=bool)
a=mmtext('Line')
b=mmdil(a,b1)
mmshow(a)
mmshow(b)
a b
