 # HtmlToImageView plugin for CakePHP
 
+This plugin renders html views as image (jpg or png) using `wkhtmltoimage` command line utility from [WkHtmlToPdf](https://wkhtmltopdf.org/) package.
+
+## Requirements
+
+- CakePHP 3.5+
+- [wkhtmltoimage](https://wkhtmltopdf.org/)
+
 ## Installation
 
-You can install this plugin into your CakePHP application using [composer](http://getcomposer.org).
+You can install this plugin into your CakePHP application using [Composer][composer].
+
+```bash
+composer require andrej-griniuk/cakephp-html-to-image-view
+```
+
+## Usage
+
+First of all you need to load the plugin in your bootstrap.php
+
+```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.
 
-The recommended way to install composer packages is:
+Default path to `wkhtmltoimage` binary is `/usr/bin/wkhtmltoimage`. You can change it by setting `HtmlToImageView.binary` configuration variable:
 
+```php
+Configure::write('HtmlToImageView.binary', '/another/path/to/wkhtmltoimage');
 ```
-composer require your-name-here/HtmlToImageView
+
+You can pass some options to `wkhtmltoimage` from your view via `$this->viewOptions(['imageOptions' => [...])`. List of available options:
+ - **crop-h** - Set height for cropping
+ - **crop-w** - Set width for cropping
+ - **crop-x** - Set x coordinate for cropping
+ - **crop-y** - Set y coordinate for cropping
+ - **format** - Output file format (jpg/png)
+ - **width** - Set screen width, note that this is used only as a guide line (default 1024)
+ - **height** - Set screen height (default is calculated from page content)
+ - **zoom** - Zoom level
+ - **quality** - Output image quality (between 0 and 100) (default 94)
+ 
+For example:
+
+```php
+$this->viewOptions([
+    'imageOptions' => [
+        'width' => 250,
+        'zoom' => 2
+    ],
+]);
 ```
