typedef struct _FTARRAY
{
L_UINT uStructSize;

} 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]. |
Comments
This structure is used only by the Fourier Transform functions:
