vb.net - 使用图像作为表单背景？

Question

如果我想从图像创建可调整大小的表单，我必须使用矢量图像吗？

一个例子是 Photoshop。它可以调整大小并保持圆角和外边缘，而不会使其看起来变形和拉伸。

我知道可以在背景中平铺简单的图案，但尝试拥有完美的圆角是一项艰巨的任务。这将如何完成？

Answer 1

You can override the OnPaint method for your form and draw the background yourself in the right size. Since you're drawing primitives (paths, rectangles, ellipses, etc.) it's not a source bitmap that gets scaled and you can adapt to the form's size.
