class Vips::Interpolate

An interpolator. One of these can be given to operations like {Vips::affine} or {Vips::mapim} to select the type of pixel interpolation to use.

To see all interpolators supported by your libvips, try

“‘ $ vips -l interpolate “`

But at least these should be available:

For example:

```ruby
im = im.affine :interpolate => Vips::Interpolate.new :bicubic
```
