Detailed Description

Iterative expansion of a binary mask, val1 is number of pixels to expand, if val2!=0 will make a soft Gaussian edge starting after val2 pixels.

Parameters:
val1 number of pixels to expand
val2 number of Gaussian pixels to expand, following the first expansion

virtual string EMAN::IterBinMaskProcessor::get_desc (  )  const [inline, virtual]

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns:
The description of this processor.

Implements EMAN::Processor.

05744                 }

virtual string EMAN::IterBinMaskProcessor::get_name (  )  const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

void IterBinMaskProcessor::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.

Parameters:
image The image to be processed.
