The FTARRAY structure contains information about the complex 2D array that will hold the frequency components of the image.
| Parameter | Description | 
| uStructureSize | 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]. |
