# Image::heighten

## Resize image proportionally to given height



> public Intervention\Image\Image heighten(integer $height, [Closure $callback])

### Parameters

#### height
The new height of the image

#### callback (optional)
Closure callback defining constraint to prevent unwanted **upsizing** of the image. See examples below.

> public Intervention\Image\Size upsize()

Keep image from being upsized.

### Return Values
Resized instance of `Intervention\Image\Image`

### Examples

```php
// resize image to new height
$img = Image::make('public/foo.jpg')->heighten(100);

// resize image to new height but do not exceed original size
$img = Image::make('public/foo.jpg')->heighten(100, function ($constraint) {
    $constraint->upsize();
});
```
