EMData * RotateFlipAligner::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.
