我在中有一个资源映像。Net Maui项目。

ImageSource imageSource = ImageSource.FromFile("somefile.jpg");

我需要将其转换为 IImage .

对于从互联网加载的图像,我会

    HttpWebRequest wreq;
    HttpWebResponse wresp;
    Stream mystream;
            
    string url = "https://someurl/somefile.jpg";

    wreq = (HttpWebRequest)WebRequest.Create(url);
    wreq.AllowWriteStreamBuffering = true;

    wresp = (HttpWebResponse)wreq.GetResponse();
    mystream = wresp.GetResponseStream();

    IImage image = PlatformImage.FromStream(mystream);

当图像作为项目资源嵌入时,我可以这样做吗?

这包含在 docs

IImage image;
Assembly assembly = GetType().GetTypeInfo().Assembly;
using (Stream stream = assembly.GetManifestResourceStream("GraphicsViewDemos.Resources.Images.dotnet_bot.png"))
{
#if IOS || ANDROID || MACCATALYST
    // PlatformImage isn't currently supported on Windows.
    image = PlatformImage.FromStream(stream);
#elif WINDOWS
    image = new W2DImageLoadingService().FromStream(stream);
#endif
}
