c# - 如何使用 Image Magick 生成与源（SVG）文件中字体相同的正确 PNG 文件？

Question

我有一个 svg 文件，其中包含图像标签（基于 url 的源图像）以及 2 个文本标签。支持字体（影响）已使用导入属性链接到 svg 文件中。

Svg 在 google chrome 浏览器上可以正确预览。但是，当我使用 Image Magick Tool 将其转换为 PNG 文件时。它导致了一些奇怪的形式。即使图像在生成的文件中也不可见。

这是我用来将 SVG 文件转换为 Png 文件的代码。

ImageMagick.MagickImage image = new ImageMagick.MagickImage(@"c:\1.svg");
image.Format = ImageMagick.MagickFormat.Png;
image.Write(@"c:\Magick.png");
