◆ feet()

bool feet ( const thisclass &  other,
Point &  p1,
Point &  p2 
) const
inline

Computes the perpendicular feet with another line.

Parameters
otherAnother line.
p1The perpendicular foot on the current line.
p2The perpendicular foot on the other line.
Returns
true if the perpendicular foots exist, and false if the two lines are parallel.
