October CMS ships with an image resizer that lets you change the shape and size of supported images. To resize an image, use the
open method on the
Resizer facade to target a file path.
$image = Resizer::open('path/to/image.jpg');
You may also pass an uploaded file from the page request input.
$image = Resizer::open(Input::file('field_name'));
To resize the image, call the
resize method on the object to perform the resize. The first argument is the image width, the second argument is the image height and the third argument is an array of resize parameters.
$image->resize(800, 600, ['mode' => 'crop']);
The width and height arguments are also optional, for example, to use the existing width and only adjust the height, pass the second argument as
null. This value is then calculated using original image ratio (automatic proportional scaling) based on the
$image->resize(800, null, [...]);
Finally, use the
save method to save the resized image to a new location.
There is also a
|resize markup filter that can be used for resizing images in your themes.
