Detailed Description

Class defining a first order low pass filter.

Constructor & Destructor Documentation

flair::filter::LowPassFilter::LowPassFilter ( const core::IODevice parent,
const gui::LayoutPosition position,
std::string  name,
const core::cvmatrix init_value = NULL 


Construct a LowPassFilter at position.
After calling this function, position will be deleted as it is no longer usefull.
The filter is automatically updated when parent's IODevice::ProcessUpdate is called.
The optional init_value parameters allow to specify the size of the input datas and its inital values. If unspecified, a 1*1 size is used, and values are initialized with 0.
