One way you can find the center point of an image is to find the width and height and divide by 2
PHP Code:
$size = getimagesize($filename);
$width = $size[0];
$height = $size[1];
$x = $width / 2;
$y = $height / 2;
Thats the way i have always done it anyway
You can always look at something like this
PHP Code:
// The file
$filename = 'test.jpg';
$percent = 0.5;
// Content type
header('Content-type: image/jpeg');
// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = $width * $percent;
$new_height = $height * $percent;
// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
// Output
imagejpeg($image_p, null, 100);
