string EMAN::MinMaxAverager::get_desc | ( | ) | const [inline, virtual] |
string EMAN::MinMaxAverager::get_name | ( | ) | const [inline, virtual] |
Get the Averager's name.
Each Averager is identified by a unique name.

TypeDict EMAN::MinMaxAverager::get_param_types | ( | ) | const [inline, virtual] |
Get Averager parameter information in a dictionary.
Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

References EMAN::EMObject::INT, and EMAN::TypeDict::put().

virtual void EMAN::MinMaxAverager::mult | ( | const float & | ) | [inline, virtual] |
Multiply the result image by some floating point constant This is useful when weighting the input images prior to calling add_image - a situation where it is likely you want to divide by the sum of the weights.
Hence call mult after all of the weighted images have been added.
