EMAN::AreaProcessor::AreaProcessor | ( | ) | [inline] |
virtual void EMAN::AreaProcessor::create_kernel | ( | ) | const [protected, pure virtual] |
Implemented in EMAN::LaplacianProcessor, and EMAN::ZeroConstantProcessor.
Referenced by process_inplace().
string EMAN::AreaProcessor::get_desc | ( | ) | const [inline, virtual] |
Get the descrition of this specific processor.
This function must be overwritten by a subclass.
Implements EMAN::Processor.
Reimplemented in EMAN::LaplacianProcessor, and EMAN::ZeroConstantProcessor.
Definition at line 2887 of file processor.h.
02888 { 02889 return "AreaProcessor use pixel values and coordinates of a real-space square area. This is the base class. Specific AreaProcessor needs to implement function create_kernel()."; 02890 }
TypeDict EMAN::AreaProcessor::get_param_types | ( | ) | const [inline, virtual] |
Get processor parameter information in a dictionary.
Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.
Reimplemented from EMAN::Processor.
Definition at line 2880 of file processor.h.
References EMAN::EMObject::INT, and EMAN::TypeDict::put().

void AreaProcessor::process_inplace | ( | EMData * | image | ) | [virtual] |
To process an image in-place.
For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.
image | The image to be processed. |
