Wpf - 调整图标大小，模糊图像数量
我尝试首先从可执行文件中提取图标，将其保存到特定文件并将其显示在 WPF 窗口中。
32x32 的质量非常好，但当我尝试将其调整到更大时，它开始变得模糊。
来自我的应用程序的图像，100x100 图像旁边的 32x32 图像：

正如您所看到的，它非常模糊，相比之下，这是来自不同应用程序的图像，该应用程序也从可执行文件（甚至更大）获取图标，因此这显然是可能的。

关于此问题有几个主题（或至少相关），但我无法弄清楚问题到底是什么。
我正在使用此代码显示图像。
<Image Height="100"
Width="100"
HorizontalAlignment="Left"
Source="{Binding ImagePath}"
RenderOptions.BitmapScalingMode="HighQuality"/>
我认为问题在于图像的显示，而不是最初如何保存它，但以防万一......我正在使用此代码保存图像。
Bitmap image = Icon.ExtractAssociatedIcon(FilePath).ToBitmap();
image.Save(imagePath, System.Drawing.Imaging.ImageFormat.Png);
I'm attempting to first pull a icon from an executable file, save it to a particular file and display that in a WPF window.
The quality is perfectly fine at 32x32 but when I try to resize it to being larger, it starts to get blurry.
Image from my application, 32x32 image beside 100x100 image:

As you can see, it's quite blurry, by comparison here's an image from a different application which is getting the icon from executable also (and even larger) so it's obviously possible.

There are several topics on this (or at least related) but I'm not managed to figure out what exactly the problem is.
I'm displaying the image using this code.
<Image Height="100"
Width="100"
HorizontalAlignment="Left"
Source="{Binding ImagePath}"
RenderOptions.BitmapScalingMode="HighQuality"/>
I assume the issue is with the displaying of the image rather then how it's saved initially but just in case...I'm saving the image using this code.
Bitmap image = Icon.ExtractAssociatedIcon(FilePath).ToBitmap();
image.Save(imagePath, System.Drawing.Imaging.ImageFormat.Png);

ExtractAssociatedIcon 仅获取 32x32 图标，即使应用程序的资源有其他图标也是如此。您可能必须一路 p/invoke 某些东西才能获取 exe 中的任何其他图标。
ExtractAssociatedIcon only gets the 32x32 icon, even if the app's resources have others. You'll probably have to go all the way to p/invoke something to get any of the other icons in an exe.
