语法

声明
Public Overrides Sub DrawToBitmap ( _
    bitmap As Bitmap, _
    targetBounds As Rectangle _
)

public override void DrawToBitmap(
    Bitmap bitmap,
    Rectangle targetBounds
)

public:
virtual void DrawToBitmap(
    Bitmap^ bitmap, 
    Rectangle targetBounds
) override

abstract DrawToBitmap : 
        bitmap:Bitmap * 
        targetBounds:Rectangle -> unit 
override DrawToBitmap : 
        bitmap:Bitmap * 
        targetBounds:Rectangle -> unit

public override function DrawToBitmap(
    bitmap : Bitmap, 
    targetBounds : Rectangle
)

参数

bitmap
类型：System.Drawing.Bitmap
要绘制的 Bitmap 。

targetBounds
类型：System.Drawing.Rectangle
中 LineShape 呈现的 Rectangle 。

备注

如果 x 或 y 协调或 targetBounds 的 width 或 height 参数小于 0， ArgumentException 将引发。

示例

下面的示例演示如何使用 DrawToBitmap 方法和 ClientRectangle 属性是在 PictureBox 控件的 OvalShape 。

Private Sub Form1_Load() Handles MyBase.Load
    Dim pic As New System.Drawing.Bitmap(Me.PictureBox1.Image, 
      PictureBox1.Width, PictureBox1.Height)
    Dim rect As New System.Drawing.Rectangle
    ' Assign the client rectangle.
    rect = OvalShape1.ClientRectangle
    ' Draw the oval on the bitmap.
    OvalShape1.DrawToBitmap(pic, rect)
    PictureBox2.Image = pic
End Sub

private void form1_Load(System.Object sender, System.EventArgs e)
{
    System.Drawing.Bitmap pic = new System.Drawing.Bitmap(this.pictureBox1.Image, 
        pictureBox1.Width, pictureBox1.Height);
    System.Drawing.Rectangle rect = new System.Drawing.Rectangle();
    // Assign the client rectangle.
    rect = ovalShape1.ClientRectangle;
    // Draw the oval on the bitmap.
    ovalShape1.DrawToBitmap(pic, rect);
    pictureBox2.Image = pic;
}
