为什么用 HalconViewer.HalconWindow.SetPart？

HalconWindow 是 HWindowControlWPF 控件自带的 HALCON 窗口对象，它的 SetPart 方法是专门为 .NET 封装的，参数类型完全匹配，不会出现 #1201 错误。

更重要的是：它和后面的 DispImage 用的是同一个窗口对象，设置的显示区域会直接生效，图像会按你的要求显示。

SetPart 参数解释

SetPart(Row1, Column1, Row2, Column2)：设置图像的显示区域，从（Row1, Column1）到（Row2, Column2）。

示例图像 fabrik 是 512×512 的，所以参数是 (0, 0, 511, 511)，表示显示整个图像，不会被裁剪或拉伸。

Dispatcher.BeginInvoke 的作用

确保 HWindowControlWPF 控件完全渲染后再执行图像操作，避免窗口句柄未初始化导致的错误。
