A bare-bones port of Mario Klingemann's stackblur that just operates on a Uint8 pixel array.
|
|
|
|
Original implementation:

|
|
# API
|
|
|
|
```
|
|
var stackblur = require('stackblur');
|
|
stackblur( pixels, width, height, radius )
|
|
```
|
|
|
|
Takes the pixel array (typically Uint8ClampedArray), the width and height of the image, and the radius to blur.
