Remap Fractional Pixel Values

Raymond_Castonguay — Wed, 10 Aug 2011 03:44:25 GMT

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
