FTARRAY

typedef struct tagFTARRAY 
{ 
   L_UINT uStructSize; 
   L_UINT uWidth; 
   L_UINT uHeight; 
   L_COMPLEX acxData[1]; 
} FTARRAY, *pFTARRAY;

The FTARRAY structure contains information about the complex 2D array that will hold the frequency components of the image.

Parameter	Description
uStructSize	FTARRAY structure size. Should be set to sizeof(FTARRAY).
uWidth	2D array width in pixels.
uHeight	2D array height in pixels.
acxData	The 2D data array. Note that, although only one element is declared in the array, the array contains uWidth * uHeight elements. The frequency component for the pixel (row, col) is acxData[row * uWidth + col].
