HIGEAR hIGear; /* HIGEAR handle of input image */ HIGCOMPLEXOBJ hIGComplexObjOut; /* HIGCOMPLEXOBJ handle of output data */ ... IG_FIP_DST_forward_from_image(hIGear, &hIGComplexObjOut); ... |
The difference between this function and IG_FIP_DST_forward() is that this function takes a HIGEAR as the input.
