Parameters:

m	center position (in pixel unit)
n	center position (in pixel unit)
r	radius (in pixel unit)
a	complex value
flag	fill inside or outside (CWO_FILL_INSIDE, CWO_FILL_OUTSIDE)

void CWO::MulCirc	(	int	m,
		int	n,
		int	r,
		cwoComplex &	a
	)

multiply complex value in circular area

Parameters:

m	center position (in pixel unit)

a	complex value

void CWO::Convolve	(	CWO &	a,
		float *	ker,
		int	Sx,
		int	Sy
	)

convolve the field with filter kernel

    @param a filtered field
    @param ker filter kernel
    @param Sx size of filter kernel
    @param Sy size of filter kernel

int CWO::ScaleReal ( float lim = 1.0 )

scale current pixels (real part of complex amplitude) by specified maximum value

   @param lim maximum value
   @image html scale1.jpg
   @note
   this function convert current pixels by the following equation:

$output~pixel = \frac{input~pixel - min}{max-min} \times lim$ where $ max, min $ are the maximum and minimum current pixel,rerspectively.

        CWO a;
        a.Load("lena.bmp"); //load bitmap image with 256 gray value
        a.Scale(128); //the maximum value of the bitmap image is 128

int CWO::ScaleReal	(	float	i1,
		float	i2,
		float	o1,
		float	o2
	)

scale real part of complex amplitude by specified range

   @param i1 
   @param i2  
   @param o1
   @param o2
   @image html scale2.jpg
   @note 
   convert the current real part from the minimum value i1 to o1.
   similarly, convert the current real part from the maximum value i2 to o2.

        CWO a;
        a.Load("lena.bmp"); //load bitmap image with 256 gray value
        a.Scale(0,255,255,0); //each pixel value of the bitmap image is inverted 

int CWO::ScaleCplx ( float lim = 1.0 )

scale complex amplitude by specified maximum value

Parameters:

lim	maximum value ]

Examples:: Phase shifting digital holography.

int CWO::ScaleCplx	(	float	i1,

	)

scalecomplex amplitude by specified range

Parameters:

i1
i2
o1
o2

Note:: convert the current complexc amplitude from the minimum value i1 to o1. similarly, convert the current complexc amplitude from the maximum value i2 to o2.
