也许您正在寻找“缩放”而不是缩放：

Instead of zoom, perhaps 'scaling' is what you're looking for:

您应该查看 FloatCanvas 或 FloatCanvas2。我知道其中之一具有缩放（也许还有平移）功能。您可以从 Whyteboard 获得有关绘制矩形的想法。这里有一些链接：

You should look at FloatCanvas or FloatCanvas2. I know one of them has a zooming (and maybe panning) feature. You can get ideas about drawing rectangles from Whyteboard. Here's a few links:
