Constructor & Destructor Documentation

◆ BilinearFilter()

Murl::Util::BilinearFilter::BilinearFilter ( Double  width = Double(1.0))
inline

The default constructor.

Parameters
widthThe filter width defaulted to 1.0.

Member Function Documentation

◆ Apply() [1/2]

virtual Double Murl::Util::BilinearFilter::Apply ( Double  dValH) const
inlinevirtual

Apply the filter horizontally.

Parameters
dValHThe horizontal distance in range [-filterWidth .. filterWidth].
Returns
(width - abs(dValH)) or zero if distance is out of range.

Implements Murl::IFilter.

References Murl::Math::Abs(), and Murl::Util::Filter::mWidth.

◆ Apply() [2/2]

virtual Double Murl::Util::BilinearFilter::Apply ( Double  dValH,
Double  dValV 
) const
inlinevirtual

Apply the filter horizontally and vertically.

Parameters
dValHThe horizontal distance in range [-filterWidth .. filterWidth].
dValVThe vertical distance in range [-filterWidth .. filterWidth].
Returns
((width - abs(dValH)) * (width - abs(dValV))) or zero if distance is out of range.

Implements Murl::IFilter.
