EMData * RotateFlipAlignerIterative::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.

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

Implements EMAN::Aligner.
