Using Preset Filters From CamanJS API

Question

I am using CamanJS plugin to apply effects to images, I want to know how do I apply preset effects like lomo, sin city, cross process, etc found here. The documentation of CamanJS does not elaborate on this properly. I tried the below code to apply vignette effect , but was not successful. ``` Caman("#effects", function () { this.resize({width: 650,height: 400 }); this.vignette(); this.render(); }); ```

Accepted Answer

The vignette filter requires a size in order to work. It can either be an absolute number or a percentage.

```
this.vignette(400);
this.vignette("10%");
```

It also takes an optional strength parameter whose range is 0-100.

```
this.vignette("10%", 40);
```

You're right though, all of the filters should be documented better.
