(PECL imagick 2.0.0)
Imagick::getSize — Returns the size associated with the Imagick object
Get the size in pixels associated with the Imagick object, previously set by Imagick::setSize().
Note:
This method just returns the size that was set using Imagick::setSize(). If you want to get the actual width / height of the image, use Imagick::getImageWidth() and Imagick::getImageHeight().
Returns the size associated with the Imagick object as an array with the keys "columns" and "rows".
Example #1 Getting the size of a raw RGB image set at 200x400, after scaling to 400x800 (compared to width / height)
<?php
//Set size first and then load the raw image
$img = new Imagick();
$img->setSize(200, 400);
$img->readImage("image.rgb");
$img->scaleImage(400, 800);
$size = $img->getSize();
print_r($size);
echo "$img->getImageWidth()."x".$img->getImageHeight();
?>
以上例程会输出：
Array
(
[columns] => 200
[rows] => 400
)
400x800
