FastImage finds the dimensions or filetype of an image at a url by fetching the least data possible

FastImage

FastImage finds the dimensions or filetype of a remote image file given its uri by fetching as little as needed, based on the excellent Ruby implementation by Stephen Sykes.

Usage

<?php 
		
require 'Fastimage.php';
		
$uri = "http://farm9.staticflickr.com/8151/7357346052_54b8944f23_b.jpg";
		
// loading image into constructor
$image = new FastImage($uri);
list($width, $height) = $image->getSize();
echo "dimensions: " . $width . "x" . $height;

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

fastimage's Issues

Cannot detect JPEG images on some platforms

I'm using fastimage in my project KCFinder. It works perfectly on my Windows workstation, but when I tried on Linux server, fastimage cannot detect the JPEG images (PNG and GIF works fine).

Windows workstation:
Windows 7 (64bit)
Apache/2.4.7
PHP 5.5.9

Linux server:
Gentoo Linux (64bit)
Apache/2.2.25
PHP 5.4.26

not working?

Thanks for your efforts, but it does not seem like the library is working? when i run the below function what i get is:

function GetSizeTest(){
  $path = libraries_get_path('fastimage');
  require_once($path."/Fastimage.php");

  $files = array(
    'http://www.google.com.eg/images/srpr/logo3w.png',
    'http://pcdn.500px.net/8123858/7051e2440a869a3fec74406a3aa200618452c390/4.jpg',

    'http://farm1.staticflickr.com/100/306618144_c2810214ee_b.jpg'
  );

  foreach($files as $file){
    $uri = $file;
    echo "=======> $uri <======\n";
    $time = microtime(true);
    $image = new FastImage($uri);
    $image->load($uri);
    echo ">FastImage: \n";
    $size = $image->getSize();
    dsm($size);
    list($width, $height) = $size;
    echo "Width: ". $width . "px Height: ". $height . "px in " . (microtime(true)-$time) . " seconds \n";

    $time = microtime(true);
    list($width, $height) = getimagesize($uri);
    echo ">Getimagesize: \n";
    echo "Width: ". $width . "px Height: ". $height . "px in " . (microtime(true)-$time) . " seconds \n";
  }
}

Am i doing anything wrong or something wrong with the library?

Slow on mine

I just tested to compare with getimagesize() function and the result also the same. Means maybe the network is the problem.

Detect ico files

I'd like fastimage could support icon files, at least in the getType() method (getSize is more complicated because the ico files can store more than one image with multiple sizes).
thanks

Composer/autoload support?

Add 'composer.json' for autoloading in projects

webp is not support

can support webp?
