The L_StartFastMagicWandEngine function must be called before calling the L_FastMagicWand and L_EndFastMagicWandEngine functions.

When the handle to the MAGICWANDHANDLE is no longer needed, it should be freed by calling L_EndFastMagicWandEngine. For every call to L_StartFastMagicWandEngine there must be a call to L_EndFastMagicWandEngine.

This function supports 1, 8, and 24-bit images.

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.
