| Values                            | Description                                                                                                                                                                                                             |

| `nearest`                         | [Nearest neighbour interpolation](http://en.wikipedia.org/wiki/Nearest-neighbor_interpolation). Suitable for image enlargement only.                                                                                    |
| `bilinear`                        | [Bilinear interpolation](http://en.wikipedia.org/wiki/Bilinear_interpolation). Faster than bicubic but with less smooth results.                                                                                        |
| `bicubic`                         | [Bicubic interpolation](http://en.wikipedia.org/wiki/Bicubic_interpolation). Default.                                                                                                                                   |
| `locallyBoundedBicubic`           | [LBB interpolation](https://github.com/jcupitt/libvips/blob/master/libvips/resample/lbb.cpp#L100).Prevents some "[acutance](http://en.wikipedia.org/wiki/Acutance)" but typically reduces performance by a factor of 2. |
| `nohalo`                          | [Nohalo interpolation](http://eprints.soton.ac.uk/268086/). Prevents acutance but typically reduces performance by a factor of 3.                                                                                       |
| `vertexSplitQuadraticBasisSpline` | [Vertex Split Quadratic Basis Spline interpolation](https://github.com/jcupitt/libvips/blob/master/libvips/resample/vsqbs.cpp#L48).                                                                                     |
