L_FreeFTArray

#include "l_bitmap.h"

L_LTIMGCOR_API L_INT L_FreeFTArray(pFTArray, uFlags)

pFTARRAY pFTArray;	pointer to structure
L_UINT32 uFlags;	flags

Frees the 2D storage array that was allocated by L_AllocFTArray.

Parameter	Description
pFTArray	Pointer to the FTARRAY structure to be freed.
uFlags	Reserved for future use. Must be 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.

This function should be called when your program no longer needs the 2D array that is used to hold Fourier Transform coefficients. This function is used only when working with the Fourier Transform functions. Do not use pFTArray after this function returns.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
