This package provides a means to load and convert .ico files in a PHP application. It has no dependencies apart from [gd](http://php.net/manual/en/book.image.php)for rendering.

The package has unit tests which verify support for 1bit, 4bit, 8bit, 24bit and 32bit .ico files, and the newer form of .ico files which can included embedded PNG files.

Installation
------------

[](#installation)

For recent php versions (8.\*) IcoFileLoader is available via Composer:

```
composer require lordelph/icofileloader
```

PHP 5.6 - 7.x
=============

[](#php-56---7x)

Earlier versions of php from 5.6 onwards can use version 2 of IcoFileLoader

```
composer require lordelph/icofileloader:2.*
```

PHP 5.4 - 5.5
=============

[](#php-54---55)

If you need to use php5.4 or php5.5, you must install the v1.\* branch

```
composer require lordelph/icofileloader:1.*
```

Usage
-----

[](#usage)

The [IcoFileService](https://github.com/lordelph/icofileloader/blob/master/src/IcoFileService.php) class provides a one-shot method `extractIcon`. This should suit most use-cases where you simply want to get one image out of a .ico file.

It returns an image resource, which you can further manipulate with [GD functions](http://php.net/gd), e.g. save it to a file with [imagepng](http://php.net/imagepng)

For example, here's how you extract a 32x32 transparent image from an ico file:

```
$loader = new Elphin\IcoFileLoader\IcoFileService;
$im = $loader->extractIcon('/path/to/icon.ico', 32, 32);

//$im is a GD image resource, so we could, for example, save this as a PNG
imagepng($im, '/path/to/output.png');
```

### Render with background color

[](#render-with-background-color)

Instead of retaining the alpha channel from the icon, you can render with a background color instead - pass the required color as a renderer option as follows:

```
$im = $loader->extractIcon('/path/to/icon.ico', 32, 32, ['background'=>'#FFFFFF']);
```

### Extract icon at any size

[](#extract-icon-at-any-size)

The `extractIcon` method will try find an image in the icon which is the exact size you request at highest color depth it can find. If it can't, it will resize the best quality image in the icon. So, you can request any size you require...

```
$im = $loader->extractIcon('/path/to/icon.ico', 100, 100);
```

### Extract icon from a URL

[](#extract-icon-from-a-url)

As long you have the PHP [fopen wrappers](http://php.net/manual/en/wrappers.php)installed, you can pass a URL to `extractIcon`

```
$im = $loader->extractIcon('https://assets-cdn.github.com/favicon.ico', 16, 16);
```

### Extract icon from binary data

[](#extract-icon-from-binary-data)

If you already have an ico file held as a binary string, `extractIcon` will cope with that just fine too:

```
$data = file_get_contents('/path/to/icon.ico');
$im = $loader->extractIcon($data, 16, 16);
```

Lower level methods
-------------------

[](#lower-level-methods)

If you want to do more than just extract a single image from an icon, you can use lower level methods of [IcoFileService](https://github.com/lordelph/icofileloader/blob/master/src/IcoFileService.php) to inspect an .ico file and perform multiple renderings.

The `fromFile`, `fromString` and `from` methods will parse an `ico` file and return an [Icon](https://github.com/lordelph/icofileloader/blob/master/src/Icon.php) instance representing an icon and the [images](https://github.com/lordelph/icofileloader/blob/master/src/IconImage.php)it contains.

You can iterate the images in icon, examine them, and render them with `renderImage`

For example, here's how you could extract all the images in an icon and save them as individual files.

```
$icon = $loader->fromFile('/path/to/icon.ico');
foreach ($icon as $idx => $image) {
     $im=$loader->renderImage($image);

     $filename=sprintf('img%d-%dx%d.png', $idx, $image->width, $image->height);
     imagepng($im, $filename);

     printf("rendered %s as %s\n", $image->getDescription(), $filename);
}
```

Internals
---------

[](#internals)

The service is composed of a [parser](https://github.com/lordelph/icofileloader/blob/master/src/IcoParser.php) and a [renderer](https://github.com/lordelph/icofileloader/blob/master/src/GdRenderer.php), which can be injected into the service at runtime if you wanted to override them.

The current [GdRenderer](https://github.com/lordelph/icofileloader/blob/master/src/GdRenderer.php) works by drawing individual pixels for BMP based icon images. This isn't going to be terribly fast. PHP 7.2 will have support for [BMP images](http://php.net/imagecreatefrombmp), and I'll add a renderer which takes advantage of that when it is released.
