HtmlToImageView plugin for CakePHP

This plugin renders html views as image (jpg or png) using wkhtmltoimage command line utility from WkHtmlToPdf package.

Requirements

• CakePHP 3.5+
• wkhtmltoimage

Installation

You can install this plugin into your CakePHP application using Composer.

composer require andrej-griniuk/cakephp-html-to-image-view

Usage

First of all you need to load the plugin in your bootstrap.php

Plugin::load('HtmlToImageView', ['bootstrap' => true, 'routes' => true]);

This will enable jpeg and png extensions on any route. Alternatively you could load the plugin without 'routes' => true and only enable extensions on the routes you would like.

Layout path and templates sub dir are img, e.g. you'll need to create src/Template/Layout/img/defaut.ctp for your image views and and image view template would be, for example, src/Template/Events/img/view.ctp. Then simply call, for example, http://localhost/events/view.jpg to render your view as image.

Default path to wkhtmltoimage binary is /usr/bin/wkhtmltoimage. You can change it by setting HtmlToImageView.binary configuration variable:

Configure::write('HtmlToImageView.binary', '/another/path/to/wkhtmltoimage');

You can pass some options to wkhtmltoimage from your view via $this->viewOptions(['imageOptions' => [...]). List of available options:

• crop-h - Set height for cropping
• crop-w - Set width for cropping
• crop-x - Set x coordinate for cropping
• crop-y - Set y coordinate for cropping
• format - Output file format (jpg/png)
• width - Set screen width, note that this is used only as a guide line (default 1024)
• height - Set screen height (default is calculated from page content)
• zoom - Zoom level
• quality - Output image quality (between 0 and 100) (default 94)

For example:

$this->viewOptions([
    'imageOptions' => [
        'width' => 250,
        'zoom' => 2
    ],
]);
