CropBundle

Scrutinizer Code Quality Build Status License Total Downloads Latest Unstable Version Latest Stable Version

This bundle is designed to create crops for images using the user-friendly UI in your forms. It uses the fengyuanchen/cropper jquery plugin and it-blaster/uploadable-bundle to handle images uploading.

Installation

Add it-blaster/crop-bundle to your composer.json file and run composer

Register the bundle in your AppKernel.php

Configure it-blaster/uploadable-bundle

Usage

1. Configure the CroppableBehavior for your table in schema.xml:

The parameter columns must contain one or more columns' names on which you want to apply this behavior (default value: image). If your table contains other file-columns and you use the UploadableBundle to handle them, don't worry: this bundle automatically adds its columns into UploadableBehavior configuration.

The CroppableBehavior creates two methods for each configured column: setCroppable<column_name> and getCroppable<column_name>. (For example, if you configured the behavior as above, in your base model will be created following methods: setCroppableFirstImage, getCroppableFirstImage, setCroppableSecondImage and getCroppableSecondImage). You have to use this methods if you want to set up the croppable FormType or get a cropped image.

2. Include bundle's resources in your page:

Also remember that this bundle doesn't contain the JQuery library that's required for the cropper plugin.

3. Configure your form:

This construction adds a crop control for a picture in your form. Required parameters width and height set up the minimum size of the crop area. You can read more about the croppable FormType's configuration in the relevant section.

After you upload an image, you'll see it with the crop area over it. Now you can select a part of the image and save crop coordinates.

4. The bundle contains a twig filter crop that provide you an ability to get a cropped image:

max_canvas_width and max_canvas_height

These two values determine the max size of canvas in which will be inserted the original image and the crop control. The original image will be scaled proportionally. If you want to disable this limitation, set 0 or false to this options. Default values: 640 and 480 pixels.
