Function Documentation

operator<<()

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

Definition at line 148 of file ossimDpt.cpp.

{
   return pt.print(os);

operator>>()

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

Expected format: ( 30.00000000000000, -90.00000000000000 ) -----—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	osimDpt to be initialized from stream.

Returns

istream pass in.
