BilinearInterpolator (Geotools modules 31-SNAPSHOT API)

Object
- BilinearInterpolator

```
public class BilinearInterpolator
extends Object
```
Interpolates a grid to a grid of different dimensions using bilinear interpolation.
NO_DATA cell values are supported in the source grid. There are two ways of handling the boundary between NO_DATA cells and data cells:
- Truncate - If any source cell is NO_DATA, the dest value is NO_DATA. This is simple and fast, but does make the data boundaries look a bit ragged.
- Smooth - If only one source cell is NO_DATA, the value is interpolated using the 3 valid values, across one-half of the interpolated cells. This smoothes off the boundary. If 2 or more source cells are NO_DATA, then Truncation is used.

    Parameters:
    
    width - the width of the destination grid
    
    height - the height of the destination grid
    
    smoothBoundary - true if boundary smoothing should be performed
    
    Returns:
    
    the interpolated grid
