Remap Fractional Pixel Values

[Raymond_Castonguay]

In the function Remap, can the PxMap and pyMap arrays contain fractional pixel values, such as (1.456, 2.534)?
If yes, is the fractional value used in the interpolation, or just rounded/truncated to integer values?

Hi,

Please find some comment from our engineer owner:
The maps values are truncated to integer values as follows:

float *xMap;
int x;
x = (int)( xMap + (1.0e-7) );

Thanks,
Chao
