Public Sub SetWrapMode (mode As WrapMode)

Parameters

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

1. Opens an Image from the Circle3.jpg file (a small, red-filled circle) and draws it to the screen.

2. Creates an ImageAttributes object and sets the WrapMode enumeration to Tile.

3. Creates a TextureBrush using the image from the Circle3.jpg file.

4. Draws a rectangle to the screen that is filled with the small, red-filled circles.

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

Remarks

Calling the SetWrapMode(WrapMode) method is equivalent to calling SetWrapMode(WrapMode, Color) and passing Color.Black for the color parameter. Color.Black specifies the color of pixels outside of a rendered image. This color is visible if the mode parameter is set to Clamp and the source rectangle passed to the DrawImage method is larger than the image itself.
