使用 imagemagick 设置质量？
我使用以下代码在网站上创建缩略图：
$small_image = new Imagick($large_path."/".$pic['image']);
$small_image->thumbnailImage(100, 0);
$small_image->writeImage($small_path."/".$pic['image']);
它设置了它自己的质量，我尝试添加
$small_image->setCompression(imagick::COMPRESSION_JPEG);
$small_image->setCompressionQuality(1);
但这并没有改变任何事情。我也尝试过，
$img = new Imagick($small_path."/".$pic['image']);
$img->setCompression(Imagick::COMPRESSION_JPEG);
echo $img->setCompressionQuality(1); // should come out ugly
$img->writeImage();
但即使这样也没有改变尺寸和质量 1.你知道我做错了什么吗？
I use the following code to create a thumbnail on the site:
$small_image = new Imagick($large_path."/".$pic['image']);
$small_image->thumbnailImage(100, 0);
$small_image->writeImage($small_path."/".$pic['image']);
It sets it's own quality and I tried adding
$small_image->setCompression(imagick::COMPRESSION_JPEG);
$small_image->setCompressionQuality(1);
But that didn't change a thing. I also tried
$img = new Imagick($small_path."/".$pic['image']);
$img->setCompression(Imagick::COMPRESSION_JPEG);
echo $img->setCompressionQuality(1); // should come out ugly
$img->writeImage();
But even that didn't change the size with quality 1. Any ideas what I'm doing wrong?

我想你想要：
注意“获取”/“设置”和“压缩”之间的“图像”。
I think you want:
Note the "Image" between the "get"/"set" and "Compression".
