fl::Rescale Class Reference

#include <convolve.h>

Inheritance diagram for fl::Rescale:

List of all members.

Public Methods
	Rescale (double a=1.0, double b=0)
	Rescale (const Image &image, bool useFullRange=true)
	Determines a transformation that pulls the pixel values into the range [0,1]. useFullRange indicates that min intensity should be 0 and max should be 1 after rescaling.
virtual Image	filter (const Image &image)
	This could be const, but it is useful to allow filters to collect statistics. Note that such filters are not thread safe.
Public Attributes
double	a
double	b

Detailed Description

If image format is floating point, then determine and apply an affine transformation x <== ax + b to the pixel values. If image format is integer, it is passed thru unmodified.

Rescale::Rescale (  double    a = 1.0, double    b = 0 )

Rescale::Rescale (  const Image &    image, bool    useFullRange = true )

Determines a transformation that pulls the pixel values into the range [0,1]. useFullRange indicates that min intensity should be 0 and max should be 1 after rescaling.
