int arParamIdeal2Observ	(	const double	dist_factor[4],
		const double	ix,
		const double	iy,
		double *	ox,
		double *	oy
	)

Convert ideal screen coordinates of a vertex to observed ones.

Ideal coordinates mean that the distortion of the camera is compensated (so a straight line looks straight). In observed coordinates the camera-distortion is not compensated and thus a straight line is not shown really straight.

Parameters:

	dist_factor	distorsion factors of used camera
	ix	x in ideal screen coordinates
	iy	y in ideal screen coordinates
	ox	resulted x in observed screen coordinates
	oy	resulted y in observed screen coordinates

Returns:

0 if success, -1 otherwise

int arParamObserv2Ideal	(	const double	dist_factor[4],
		const double	ox,
		const double	oy,
		double *	ix,
		double *	iy
	)

Convert observed screen coordinates of a vertex to ideal ones.

Ideal coordinates mean that the distortion of the camera is compensated (so a straight line looks straight). In observed coordinates the camera-distortion is not compensated and thus a straight line is not shown really straight.

Parameters:

	dist_factor	distorsion factors of used camera
	ox	x in observed screen coordinates
	oy	y in observed screen coordinates
	ix	resulted x in ideal screen coordinates
	iy	resulted y in ideal screen coordinates

Returns:

0 if success, -1 otherwise
