参数

示例

下面的代码示例设计用于 Windows 窗体，它需要 PaintEventArgse，这是 Paint 事件处理程序的参数。 该示例执行以下操作：

1. 从 Circle3.jpg 文件（一个红色的小圆圈）打开一个 Image 文件，并将其绘制到屏幕。

2. 创建一个 ImageAttributes 对象并将枚举设置为 WrapModeTile.

3. 从 Circle3.jpg 文件创建使用 TextureBrush 映像。

4. 向屏幕绘制一个矩形，该矩形填充了小的红色圆圈。

void SetWrapModeExample( PaintEventArgs^ e )
{
   // Create a filled, red circle, and save it to Circle3.jpg.
   Bitmap^ myBitmap = gcnew Bitmap( 50,50 );
   Graphics^ g = Graphics::FromImage( myBitmap );
   g->Clear( Color::White );
   g->FillEllipse( gcnew SolidBrush( Color::Red ), Rectangle(0,0,25,25) );
   myBitmap->Save( "Circle3.jpg" );

   // Create an Image object from the Circle3.jpg file, and draw it
   // to the screen.
   Image^ myImage = Image::FromFile( "Circle3.jpg" );
   e->Graphics->DrawImage( myImage, 20, 20 );

   // Set the wrap mode.
   ImageAttributes^ imageAttr = gcnew ImageAttributes;
   imageAttr->SetWrapMode( WrapMode::Tile );

   // Create a TextureBrush.
   Rectangle brushRect = Rectangle(0,0,25,25);
   TextureBrush^ myTBrush = gcnew TextureBrush( myImage,brushRect,imageAttr );

   // Draw to the screen a rectangle filled with red circles.
   e->Graphics->FillRectangle( myTBrush, 100, 20, 200, 200 );
}

private void SetWrapModeExample(PaintEventArgs e)
{
             
    // Create a filled, red circle, and save it to Circle3.jpg.
    Bitmap myBitmap = new Bitmap(50, 50);
    Graphics g = Graphics.FromImage(myBitmap);
    g.Clear(Color.White);
    g.FillEllipse(new SolidBrush(Color.Red),
        new Rectangle(0, 0, 25, 25));
    myBitmap.Save("Circle3.jpg");
             
    // Create an Image object from the Circle3.jpg file, and draw it
    // to the screen.
    Image myImage = Image.FromFile("Circle3.jpg");
    e.Graphics.DrawImage(myImage, 20, 20);
             
    // Set the wrap mode.
    ImageAttributes imageAttr = new ImageAttributes();
    imageAttr.SetWrapMode(WrapMode.Tile);
             
    // Create a TextureBrush.
    Rectangle brushRect = new Rectangle(0,0,25,25);
    TextureBrush myTBrush = new TextureBrush(myImage, brushRect, imageAttr);
             
    // Draw to the screen a rectangle filled with red circles.
    e.Graphics.FillRectangle(myTBrush, 100, 20, 200, 200);
}

Public Sub SetWrapModeExample(ByVal e As PaintEventArgs)

    ' Create a filled, red circle, and save it to Circle3.jpg.
    Dim myBitmap As New Bitmap(50, 50)
    Dim g As Graphics = Graphics.FromImage(myBitmap)
    g.Clear(Color.White)
    g.FillEllipse(New SolidBrush(Color.Red), New Rectangle(0, 0, _
    25, 25))
    myBitmap.Save("Circle3.jpg")

    ' Create an Image object from the Circle3.jpg file, and draw

    ' it to the screen.
    Dim myImage As Image = Image.FromFile("Circle3.jpg")
    e.Graphics.DrawImage(myImage, 20, 20)

    ' Set the wrap mode.
    Dim imageAttr As New ImageAttributes
    imageAttr.SetWrapMode(WrapMode.Tile)

    ' Create a TextureBrush.
    Dim brushRect As New Rectangle(0, 0, 25, 25)
    Dim myTBrush As New TextureBrush(myImage, brushRect, imageAttr)

    ' Draw to the screen a rectangle filled with red circles.
    e.Graphics.FillRectangle(myTBrush, 100, 20, 200, 200)
End Sub

注解

调用该方法SetWrapMode(WrapMode)等效于为SetWrapMode(WrapMode, Color)参数调用Color.Black和传递color。 Color.Black 指定呈现的图像之外像素的颜色。 如果模式参数设置为 Clamp ，并且传递给 DrawImage 该方法的源矩形大于图像本身，则此颜色可见。
