Filterous
=========
Image manipulation library in JavaScript that applies filters to photos à la Instagram on browser.
This script take pixel data from a photo that you want to give filter effects, and maniplute its pixels using the `canvas` element.
The finished photo can be displayed as `canvas`, or as downloadable image formats such as `jpeg`, `png`, or `webp` for Chrome.
This works on modern mobile browsers as well.
> Created by [Tomomi Imura](https://github.com/girliemac)
## Simple Demo
[Filterous Demo](http://girliemac.github.io/Filterous/demo)
## Real-life Example App
[W3C CoreMob camera - Mobile Web App](http://coremob.github.io/camera/vanilla/index.html)
## Installation
Just include `filterous.js` in your HTML file.
```html
```
Filterous does not require any other depencies.
## Basic Usage
Create a new instance.
```javascript
var f = new Filterous(imageObject);
```
Leaving the second param results a finished photo as a canvas, otherwise in a specified images format.
```javascript
var f = new Filterous(imageObject, 'jpeg');
```
Apply a filter (or multiple filters) then render.
```javascript
f.filterImage('brightness', 50);
f.render();
```
### Examples of using other filters
```javascript
f.filterImage('grayscale');
f.filterImage('rgbAdjust', [1.4, 1.2, 1]);
f.filterImage('convolute', [ 0, 0, 0,
0, 1, 0,
0, 0, 0 ]
);
```
or add an image layer:
```javascript
var starryLayer = new Image();
starryLayer.src = 'effects/stars.png';
var f = new PhotoFilter(Filterous, 'jpeg');
f.applyLayer(starryLayer);
f.render();
```
Reset:
```javascript
f.reset();
```
## Using Presets (instead of defining filters manually)
- Import `filterousEffects.js`.
- Include the `effects` folder (contains the overlay image).
```html
```
```javascript
ApplyEffects.nostalgia(imageObject, 'jpeg');
```
Take a look at the `filterousEffects.js` to see all available presets.
