I'm receiving Images from URLs and I would like to save these images into a new directory, in three different sizes. I'm already getting the URLs here, now I just need a way to resize each image, with a specific height and width.
I dont want to resize uploaded images, only Images from a specific URL.
My code:
$content = file_get_contents('http://www.joomlaworks.net/images/demos/galleries/abstract/7.jpg');
$name = "http://www.joomlaworks.net/images/demos/galleries/abstract/7.jpg";
$parts = explode('.', $name);
$new_url = rand(0, pow(10, 5)) . '_' . time() . '.' . $parts[count($parts) - 1];
file_put_contents(DIRECTORY.'/' . $new_url , $content);
How can I do that? Thanks.
here is the solution based on imagecopyresampled
(GD library) http://php.net/manual/en/function.imagecopyresampled.php
$content = file_get_contents('http://www.joomlaworks.net/images/demos/galleries/abstract/7.jpg');
$name = "http://www.joomlaworks.net/images/demos/galleries/abstract/7.jpg";
$parts = explode('.', $name);
$new_url = rand(0, pow(10, 5)) . '_' . time() . '.' . $parts[count($parts) - 1];
file_put_contents(DIRECTORY.'/' . $new_url , $content);
resizeImage($new_url, DIRECTORY.'/1_' . $new_url, 100, 100);
resizeImage($new_url, DIRECTORY.'/2_' . $new_url, 200, 200);
resizeImage($new_url, DIRECTORY.'/3_' . $new_url, 300, 300);
function resizeImage($source, $dest, $new_width, $new_height)
{
list($width, $height) = getimagesize($source);
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($source);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagejpeg($image_p, $dest, 100);
}
