是否有可能与透明图像两个重叠的PictureBox控件？ [英] Is it possible to have two overlapping PictureBox controls with transparent images?

问题描述

有两个重叠 图片框控制中，我试图使画面中的透明区域让控制之下（在z顺序）是可见的。

Having two overlapping PictureBox controls, I'm trying to make the transparent areas of the picture box let the controls below (in the z-order) being visible.

即使尝试微软建议，我不能得到想要的的结果。

Even after trying what Microsoft suggests, I cannot get the desired result.

这是我目前有：

这就是我想要的：

所以我的问题是：

任何方式来实现我与期望的结果两个图片框控件（或另一种方式）相互重叠的，让透明区域，通过亮？

Any way to achieve my desired result with two PictureBox controls (or with another way) that overlap each other and let the transparent areas shine through?

更新：

其实我解决了它使用这个答案到的SO问题<一href="http://stackoverflow.com/questions/395256/transparent-images-with-c-sharp-winforms">Transparent用C＃的WinForms图片。

Actually I solved it by using this answer to the the SO question "Transparent images with C# WinForms".

推荐答案

试试这个

private void Form1_Load(object sender, EventArgs e)
{
  // Transparent background...  
  pictureBoxOverlay.BackColor = Color.Transparent;

  // Change parent for overlay PictureBox...
  pictureBoxOverlay.Parent    = pictureBoxMain;

 // Change overlay PictureBox position in new parent...
 // pictureBoxOverlay.Location  = new Point(0, 0);
}

结果
