Function Documentation

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const ossimIpt &	pt
	)

Definition at line 134 of file ossimIpt.cpp.

References ossimIpt::print().

{
   return pt.print(os);
}

operator>>()

std::istream& operator>>	(	std::istream &	is,
		ossimIpt &	pt
	)

Expected format: ( 30, -90 ) -x- -y-

This method starts by doing a "makeNan" on pt. So if anything goes wrong with the stream or parsing pt could be all or partially nan.

Parameters

is	Input stream istream to formatted text.
pt	osimIpt to be initialized from stream.

Returns

istream pass in.
