Detailed Description

template<class T>
class claraty::Rescale_Op< T >

An operation to rescale all pixels in an Image to be between a specified minimun and maximum value.

Definition at line 40 of file rescale_op.h.

Constructor & Destructor Documentation

template<class T>
claraty::Rescale_Op< T >::Rescale_Op ( T  min = 0,
T  max = 0 
) [inline]

Creates a rescaling operation that rescales an Image to values between min and max (if a value is not specified, zero is used).

Parameters:
min the minimum value to rescale to
max the maximum value to rescale to

Definition at line 51 of file rescale_op.h.

00051 : _min(min), _max(max) {};

Member Function Documentation

template<class T>
template<class TS, class TD>
void claraty::Rescale_Op< T >::filter ( Image< TS >  src_image,
Image< TD > &  dest_image 
)

Rescales the src_image to be between the operation's min and max value and places the result in dest_image. If dest_image is not the same size as src_image, it is resized.

Parameters:
src_image the image to be rescaled
dest_image the output (scaled image)
