如何把picturebox保存

[tjzhangwei]

我在picturebox中用画笔绘制图线,怎样把它保存??

[warrior]

调用picturebox.Image.Save()

[tjzhangwei]

但是画的图线没有了.只有那个图片

定义个bitmap对象并在其上画，画好后再赋值给picturebox进行显示，保存的时候直接从bitmap对象对象进行保存

不太明白,能不能写个简单的代码

[yanlongwuhui]

参考如下

  Dim g As Graphics
        Dim objbmp As New Bitmap(200, 300, System.Drawing.Imaging.PixelFormat.Format24bppRgb)
        g = Graphics.FromImage(objbmp)
        g.DrawString("中国", New Font("楷体_GB2312", 40), Brushes.Blue, 0, 8)
        objbmp.Save("c:\222.bmp")
        g.Dispose()
        PictureBox1.Image = objbmp

参考如下

VB.NET code Dim g As Graphics
Dim objbmp As New Bitmap(200, 300, System.Drawing.Imaging.PixelFormat.Format24bppRgb)
g = Graphics.FromImage(objbmp)
g.DrawString("中国", New Font("楷体_GB2312", 40), Brushes.Blue, 0, 8)
objbmp.Save("c:\222.bmp")
g.Dispose()
PictureBox1.Image = objbmp
