推荐答案

您可以从发布的链接中使用项目，然后使用

You could use the project from the link you posted and then use the

drawArea.DrawToBitmap()

创建位图的方法.然后可以将此位图另存为* .bmp，*.jpg ...

好，

这是一个示例:

method to create a bitmap. This bitmap can then be saved as*.bmp, *.jpg...

Ok,

here is an example:

private void toolStripButtonSave_Click(object sender, EventArgs e)
{
  int w = drawArea.Width;
  int h = drawArea.Height;
  Bitmap bmp = new Bitmap(w, h);
  drawArea.DrawToBitmap(bmp, Rectangle.FromLTRB(0, 0, w, h));
  bmp.Save("C:\\Temp\\test.jpg");
  CommandSave();
}

如您所见，我修改了保存"工具栏按钮的事件处理程序.我已经对其进行了测试，并且效果很好！

As you can see I modified the event handler for the "Save" toolbar button. I have tested it and it works fine!
