Quill ImageResize Module

A module for Quill rich text editor to allow images to be resized.

Fork reasons

In APOIA.se we needed to use both quill-image-resize-module and quill-delta-to-html. The image resize module used the style attribute to align elements with the alignment toolbar, but the delta to html doesn't know how to parse that unless we align the line containing the image using Quill's Parchment.

Plunker

Usage

Webpack/ES6

import Quill from 'quill';
import { ImageResize } from '@apoiase/quill-image-resize-module';

Quill.register('modules/imageResize', ImageResize);

const quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        imageResize: {
            // See optional "config" below
        }
    }
});

Script Tag

Copy image-resize.min.js into your web root or include from node_modules

<script src="/node_modules/quill-image-resize-module/image-resize.min.js"></script>

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            // See optional "config" below
        }
    }
});

Config

For the default experience, pass an empty object, like so:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {}
    }
});

Functionality is broken down into modules, which can be mixed and matched as you like. For example, the default is to include all modules:

const quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            modules: [ 'Resize', 'DisplaySize', 'Toolbar' ]
        }
    }
});

Each module is described below.

Resize - Resize the image

Adds handles to the image's corners which can be dragged with the mouse to resize the image.

The look and feel can be controlled with options:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            // ...
            handleStyles: {
                backgroundColor: 'black',
                border: 'none',
                color: white
                // other camelCase styles for size display
            }
        }
    }
});

DisplaySize - Display pixel size

Shows the size of the image in pixels near the bottom right of the image.

The look and feel can be controlled with options:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            // ...
            displayStyles: {
                backgroundColor: 'black',
                border: 'none',
                color: white
                // other camelCase styles for size display
            }
        }
    }
});

Toolbar - Image alignment tools

Displays a toolbar below the image, where the user can select an alignment for the image.

The look and feel can be controlled with options:

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            // ...
            toolbarStyles: {
                backgroundColor: 'black',
                border: 'none',
                color: white
                // other camelCase styles for size display
            },
            toolbarButtonStyles: {
                // ...
            },
            toolbarButtonSvgStyles: {
                // ...
            },
        }
    }
});

BaseModule - Include your own custom module

You can write your own module by extending the BaseModule class, and then including it in the module setup.

For example,

import { Resize, BaseModule } from '@apoiase/quill-image-resize-module';

class MyModule extends BaseModule {
    // See src/modules/BaseModule.js for documentation on the various lifecycle callbacks
}

var quill = new Quill(editor, {
    // ...
    modules: {
        // ...
        ImageResize: {
            modules: [ MyModule, Resize ],
            // ...
        }
    }
});
