FlashImage

Get the type & size information of an image by fetching as little as possible., _(*1)

This project is a fork of Fastimage library by Tom Moor, which itself is a port of Ruby implementation by Stephen Sykes, _(*2)

The main difference with the original library is that this one uses a PSR-7 compatible HTTP adapter to fetch image from the web, thanks to Ivory HTTP library by Eric Geloen, _(*3)

Installation

The recommended way to install FlashImage is by using Composer, _(*4)

To add FlashImage as dependency to your project, add a dependency on nazieb/flashimage to your project's composer.json file., _(*5)

{
    "require": {
        "nazieb/flashimage": "~1.0"
    }
}
````

## Usage

The main class of the FlashImage is the `Flashimage\Factory` which will load the image and initialize all the resource needed to fetch the data

```php  
$uri = "http://farm9.staticflickr.com/8151/7357346052_54b8944f23_b.jpg";

// loading image into constructor
$image = new Flashimage\Factory($uri);
list($width, $height) = $image->getSize();
echo "dimensions: " . $width . "x" . $height;

// or, create an instance and use the 'load' method
$image = new Flashimage\Factory();
$image->load($uri);
$type = $image->getType();
echo "filetype: " . $type;

Supported Formats

Currently FlashImage only support 4 types of image: png, jpeg, bmp, gif., _(*6)
