EMData * RotateTranslateFlipAligner::align	(	EMData *	this_img,
		EMData *	to_img,
		const string &	cmp_name = "dot",
		const Dict &	cmp_params = Dict()
	)			const [virtual]

To align 'this_img' with another image passed in through its parameters.

The alignment uses a user-given comparison method to compare the two images. If none is given, a default one is used.

Parameters:

	this_img	The image to be compared.
	to_img	'this_img" is aligned with 'to_img'.
	cmp_name	The comparison method to compare the two images.
	cmp_params	The parameter dictionary for comparison method.

Returns:

The aligned image.
