struct

For lmrcImageWindowing

typedef struct lmrcImageWindowingInfo {
	long  flagWy;
	float Wy;

	long flagWx;
	float Wx;

	long  flagWyMax;
	float WyMax;

API

Windowing Function

extern void lmrcImageWindowing(mrcImage* dst, mrcImage* src, 
	lmrcImageWindowingInfo* info, long mode);

Select a preprocess method by higher bit of mode.

mode&0xf0	Preprocess
0x00	As info->Offset is 0.
0x01	As info->Offset is average value.
Otherwise	Not process

Select how to multiply Window Function by lower bit of mode.

mode&0xf	Windowing Function
0	Multiply Cosine Windowing to outer data than 10% edge.
1	(1-1/Wy)As data at top of image is average value.
2	Multiply 0 to outer data than WxMax(WyMax)%, and multiply Cosine Windowing to data between WxMax(WyMax)% and Wx(Wy)% .
