Imagick::getSize()

(PECL imagick 2.0.0)

Returns the size associated with the Imagick object

说明

Imagick::getSize(void): array

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().

返回值

Returns the size associated with the Imagick object as an array with the keys "columns" and "rows".

范例

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
