aspectratio


Image aspect ratio utilities.

Install

``
npm install aspectratio --save
`

API

`js
var aspect = require('aspectratio');
`

$3

Apply a fixed aspect ratio crop without distoring the image aspect ratio.

* integer width - original image width
* integer height - original image height
* string ratio - new image ratio

> The ratio must be on the following format: x:y where x and y are
> integers. The order of x and z does not matter and 3:4 will be treated
> as 4:3.

> By default #crop() will match the orientation of the original image unless a
> forced orientation is given on the follwing format: x:y!z where z is
> the orientation (v for vertical, or h for horizontal).

#### Return

This will return an Array of four values:

1. integer x - top lef x coordinate
2. integer y - top lef y coordinate
3. integer width - new image width
4. integer height - new image height

#### Example

`js
var crop = aspect.crop(2048, 768, '4:3');
// [512, 768, 1024, 768]
`
