我希望你们都很好，今天我遇到了一个非常令人困惑的问题。我正在尝试制作一个简单的应用程序，可以将 PSD 转换为透明 PNG。但我对我得到的结果并不满意。

我正在使用带有 C# 的 Magick.NET-Q16-x86.DLL (MagickImage)

以下是我的代码片段，请查看：

ImageMagick.MagickImage image = new MagickImage(filePath+"[0]");
image.Density = new Density("300");
image.Format = MagickFormat.Png32;
image.Write(outputFolder + @"\" + Path.GetFileNameWithoutExtension(filePath) + ".png");

这是解释问题的图像：（左侧是预期结果，右侧图像是我得到的）

在此处输入图像描述

所以我不明白这里发生了什么。如果我能得到任何答案，我将不胜感激。非常感谢您的审阅！

最好的，马赫

此图像的问题在于它不包含“合并图像”。这是结合了 PSD 文件中所有图层的图像。读者现在自己创建了这个合并的图像。

问题在于 ImageMagick/Magick.NET 不支持 Photoshop 的所有功能，这就是它创建此图像的原因。将来可能可以读取图像，但实现所有 PSD 功能将花费大量时间。
