Imagick不会正确地呈现svg不透明度

I need same output from Inkscape and Imagick.

我需要从Inkscape和Imagick中获得相同的输出。

This is the expected result, exported from Inkscape.

这是预期的结果，从墨水风景出口。

However, the PHP code below outputs the following faulty result.

但是，下面的PHP代码输出如下错误的结果。

PHP code:

PHP代码:

<?php
$im = new Imagick();

$im->setResolution(400,400);
$im->setBackgroundColor(new ImagickPixel('transparent'));
$im->readImageBlob(str_replace(array("color1", "color2"), array("yellow", "blue"), file_get_contents("img.svg")));

$im->setImageFormat("png");
header("Content-type: image/png");
echo $im;
?>

SVG code:

SVG代码:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="400" height="400">
<rect width="100%" height="100%" fill="green" />
<path d="M250 150 L150 350 L350 350 Z" opacity="0.9" fill="color1" />
<path d="M150 50 L50 250 L250 250 Z" opacity="0.9" fill="color2" />
</svg>

What version of PHP and ImageMagick are you running? Please share the relevant output of phpinfo(). Could this ImageMagick bug be affecting you? Or if you're not up to date, could another ImageMagic bug be affecting you?

您正在运行哪个版本的PHP和ImageMagick ?请分享phpinfo()的相关输出。这个ImageMagick bug会影响你吗?或者如果你不最新，另一个ImageMagic bug会影响你吗?

EDIT: I don't have easy access to a server with PHP's ImageMagick libraries installed at the moment, but if I find one, I'll test the code provided and post my results.

编辑:我目前无法轻松访问安装了PHP ImageMagick库的服务器，但如果找到了，我将测试提供的代码并发布结果。

EDIT2: Looks like others have the same issue, unless that forum post was also yours...

看起来其他人也有同样的问题，除非那个论坛帖子也是你的。

According to this forum post, you could try:

根据这篇论坛文章，你可以试试:

$im->setImageFormat("png32");

One person reported that worked, but another said it did not...

有一个人说这种方法有效，但另一个人说没有……

Inkscape uses the not ubiquitously supported opacity property. Use fill-opacity and stroke-opacity instead.

Inkscape使用不受普遍支持的不透明属性。使用填充-不透明度和笔划-不透明度代替。

This is already fixed in current version of Imagick.

这已经在当前版本的Imagick中得到了修正。
