Setting up Pintura Image Editor with Dropzone

For a quick start use the Dropzone example project as a guideline.

To set up the editor with Dropzone we use the useEditorWithDropzone plugin which is included in the product package.

Before continuing it's highly recommended to read the JavaScript installation guide as it clarifies important internal functionality of the image editor.

Default implementation example

In the default example below we'll use the openDefaultEditor method to quickly create an image editor.

This creates a "default" editor that has all available plugins loaded and comes preset with all plugin default options and English locale. Each of these settings can be adjusted freely.

<!-- Dropzone field -->

<!-- Dropzone scripts -->
<script src="https://unpkg.com/dropzone"></script>

<!-- Pintura Image Editor plugin -->
<script src="./useEditorWithDropzone-iife.js"></script>

<script type="module">
    // import Pintura Image Editor functionality
    import { openDefaultEditor } from './pintura/pintura.js';

    // Create a Dropzone
    Dropzone.options.pinturaDropzone = useEditorWithDropzone(
        // Method used to create the editor
        openDefaultEditor,

        // The editor options
        {
            imageCropAspectRatio: 1,
        },

        // Dropzone options
        {
            url: '/post',
            addRemoveLinks: true,
        }
    );
</script>

Advanced implementation example

In this example we'll create a custom editor, using a custom set of plugins, locale, and available options.

While this example is a lot more verbose it does allow us to create a more optimal editor package. The build process will tree-shake unused functionality resulting in a smaller build target.

            shapePreprocessor: createDefaultShapePreprocessor(),

            // This will set a square crop aspect ratio
            imageCropAspectRatio: 1,

            // Set locale
            locale: {
                ...locale_en_gb,
                ...plugin_crop_locale_en_gb,

Next steps

With the editor set up, we can continue to configure the editor to our liking by adjusting the available options exposed by the editor API
