Imagick::transformImage — Convenience method for setting crop size and the image geometry
此函数在 Imagick 3.4.4 中被 废弃，强烈建议不要应用此函数。
A convenience method for setting crop size and the image geometry from strings. 此方法在Imagick基于ImageMagick 6.2.9以上版本编译时可用。
cropA crop geometry string. This geometry defines a subregion of the image to crop.
geometryAn image geometry string. This geometry defines the final size of the image.
Returns an Imagick object containing the transformed image.
Example #1 Using Imagick::transformImage():
The example creates a 100x100 black image.
<?php
$image = new Imagick();
$image->newImage(300, 200, "black");
$new_image = $image->transformImage("100x100", "100x100");
$new_image->writeImage('test_out.jpg');
?>
