Detailed Description

LineSE - a line structuring element with arbitrary length and angle.

The line is defined with the help of a Besenham algorithm.

Note

• one edge of the structuring element is at the origin. So this S.E. isn't symetric. If you need a symetric S.E. you need to compose it with its transposed. As an example :

     import smilPython as sp
  
     # this way
     se = sp.LineSE(10, 0)
     se = se.merge(se.transpose())
  
     # or this way
     se = sp.LineSE(10, 0)
     se = sp.merge(se, se.transpose())

Constructor & Destructor Documentation

LineSE()

LineSE ( int  length, double  theta  )

inline

LineSE() - flat structuring element of arbitrary length and direction starting at the origin.

Parameters

[in]	length	: length of the segment
[in]	theta	: angle (in radians) with the horizongal line

Note

• the angle theta is defined in the usual counterclockwise direction (trigonometric convention).
