Imagick::thumbnailImage — Changes the size of an image
$columns,$rows,$bestfit = false,$fill = false,$legacy = false
Changes the size of an image to the given dimensions and removes any
associated profiles. The goal is to produce small, low cost thumbnail
images suited for display on the Web.
If true is given as a third parameter then columns and rows parameters
are used as maximums for each side. Both sides will be scaled down until
they match or are smaller than the parameter given for the side.
注意: 參數
bestfit的特性在 Imagick 3.0.0 中已改變。在此版本以前，當目標尺寸設為 400x400 時(shí)，原尺寸為 200x150 的圖像將不會(huì )被改變。自 Imagick 3.0.0 起，源圖像將會(huì )被放大到 400x300 因為這將更好的適合目標尺寸。當使用參數bestfit時(shí)，必須同時(shí)給出寬度和高度。

rowsImage height
bestfitWhether to force maximum values
成功時(shí)返回 true。
錯誤時(shí)拋出 ImagickException。
示例 #1 Imagick::thumbnailImage()
<?php
function thumbnailImage($imagePath) {
$imagick = new \Imagick(realpath($imagePath));
$imagick->setbackgroundcolor('rgb(64, 64, 64)');
$imagick->thumbnailImage(100, 100, true, true);
header("Content-Type: image/jpg");
echo $imagick->getImageBlob();
}
?>
