Question

我希望你们都很好，今天我遇到了一个相当令人困惑的问题。我正在尝试制作一个可以将PSD转换为透明PNG的简单应用程序。但我对我得到的结果不满意。

我在C＃中使用Magick.NET-Q16-x86.DLL（MagickImage）

以下是我的代码段，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");

以下是解释问题的图片：（左侧是预期结果，右侧图像是我得到的）

所以我不明白这里发生了什么。如果我能得到任何答案，我真的很感激。非常感谢您的评论！

最佳，马赫

Answer 1

此图片的问题在于它不包含合并的图片＆＃39;。这是组合PSD文件中所有图层的图像。读者现在可以创建这个合并的图像。

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。未来可能会读取图像，但实现所有PSD功能需要花费大量时间。
