Function Documentation

◆ operator<<()

template<class Type >

std::ostream& operator<<	(	std::ostream &	os,
		vgl_line_2d< Type > const &	l
	)

Write line description to stream: "<vgl_line_2d ax+by+c=0>".

Definition at line 100 of file vgl_line_2d.hxx.

◆ operator>>()

template<class Type >

std::istream& operator>>	(	std::istream &	is,
		vgl_line_2d< Type > &	line
	)

Read in three line parameters from stream.

Either just reads three blank-separated numbers, or reads three comma-separated numbers, or reads three numbers in parenthesized form "(123, 321, 567)" or reads the formatted form "123x+321y+567=0"
