小编vol*_*Art的帖子

我发现了一个有趣的程序,允许您在桌面和窗口上叠加雪花.作为编程挑战,我有兴趣试图弄清楚如何自己做这件事.更不用说这个程序有点内存耗费(如果它没有内存泄漏).以下是我的开始.我试图通过一个图像得到基础,然后将扩展.

我在答案部分下面发布了一个解决方案,但它比我想要的CPU密集度更高,有什么想法吗？

WPF XAML代码:

<Window x:Class="MainWindow"

    </Grid>
</Window>

VB代码:

Imports System.ComponentModel

    Class MainWindow
        Dim bw As BackgroundWorker = New BackgroundWorker
        Dim flake0 As New flake

        Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
            grid1.DataContext = flake0
            AddHandler bw.DoWork, AddressOf backgroundMover
            bw.RunWorkerAsync()
        End Sub

        Private Sub backgroundMover(ByVal …
