README

This field extends Image Field adding a handy cropper to manipulate images. Can be configurable in the same way as a File field in Nova.

Demo

Install

Run this command into your nova project: composer require r64/nova-image-cropper

Add it to your Nova Resource:

use R64\NovaImageCropper\ImageCropper;

ImageCropper::make('Photo'),

Update form

In order to edit the existing image saved in the model, ImageCroper uses the preview method to return a base64 encoded image. You can either use the default implementation or override it as long as you return a base64 image.

use R64\NovaImageCropper\ImageCropper;

ImageCropper::make('Photo')
        ->preview(function () {
            if (!$this->value) return null;

            $url = Storage::disk($this->disk)->url($this->value);
            $filetype = pathinfo($url)['extension'];
            return 'data:image/' . $filetype . ';base64,' . base64_encode(file_get_contents($url));
        });

Options

Avatar mode

You can add a rounded mask to the preview and the cropper

ImageCropper::make('Photo')->avatar()

Custom aspect ratio

Define the fixed aspect ratio of the crop box. By default, the crop box is free ratio.

• Type: Number
• Default: NaN

ImageCropper::make('Photo')->aspectRatio(16/9)
