# png-info
Get information about a PNG from its headers

# Install

`npm install png-info`

# Usage

Most common lookups will have methods on pngInfo:

```javascript
var image = fs.readFileSync('path/to/image.png');
var pngInfo = new PNGInfo(image);
var dimensions = pngInfo.getDimensions();
// {width: 100, height: 150 }
});
```

If you want to go deeper, you can access chunk data directly:

```javascript
var image = fs.readFileSync('path/to/image.png');
var pngInfo = new PNGInfo(image);
var width = pngInfo.chunks.IHDR.width;
// 100
```
