The following examples take the 4608x3072px original image
|
|
and resize to 480x320px using various interpolators.
|
|
|
|
To fetch the original 4608x3072px image and
|
|
generate the interpolator sample images:
|
|
|
|
```sh
|
|
curl -O https://farm6.staticflickr.com/5682/21978966091_b421afe866_o.jpg
|
|
node generate.js
|
|
```
