TextureBrush Class

Definition

Each property of the TextureBrush class is a Brush object that uses an image to fill the interior of a shape. This class cannot be inherited.

public ref class TextureBrush sealed : System::Drawing::Brush
public sealed class TextureBrush : System.Drawing.Brush
type TextureBrush = class
    inherit Brush
Public NotInheritable Class TextureBrush
Inherits Brush
Inheritance

Examples

The following code example demonstrates how to obtain a new bitmap using the FromFile method. It also demonstrates a TextureBrush.

This example is designed to be used with Windows Forms. Create a form containing a button named Button2. Paste the code into the form and associate the Button2_Click method with the button's Click event.

private:
   void Button2_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      try
      {
         Bitmap^ image1 = dynamic_cast<Bitmap^>(Image::FromFile( "C:\\Documents and Settings\\"
         "All Users\\Documents\\My Music\\music.bmp", true ));
         TextureBrush^ texture = gcnew TextureBrush( image1 );
         texture->WrapMode = System::Drawing::Drawing2D::WrapMode::Tile;
         Graphics^ formGraphics = this->CreateGraphics();
         formGraphics->FillEllipse( texture, RectangleF(90.0F,110.0F,100,100) );
         delete formGraphics;
      }
      catch ( System::IO::FileNotFoundException^ ) 
      {
         MessageBox::Show( "There was an error opening the bitmap."
         "Please check the path." );
      }
   }
private void Button2_Click(System.Object sender, System.EventArgs e)
{
    try
    {
        Bitmap image1 = (Bitmap) Image.FromFile(@"C:\Documents and Settings\" +
            @"All Users\Documents\My Music\music.bmp", true);

        TextureBrush texture = new TextureBrush(image1);
        texture.WrapMode = System.Drawing.Drawing2D.WrapMode.Tile;
        Graphics formGraphics = this.CreateGraphics();
        formGraphics.FillEllipse(texture, 
            new RectangleF(90.0F, 110.0F, 100, 100));
        formGraphics.Dispose();
    }
    catch(System.IO.FileNotFoundException)
    {
        MessageBox.Show("There was an error opening the bitmap." +
            "Please check the path.");
    }
}
Private Sub Button2_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button2.Click
    Try
        Dim image1 As Bitmap = _
            CType(Image.FromFile("C:\Documents and Settings\" _
            & "All Users\Documents\My Music\music.bmp", True), Bitmap)

        Dim texture As New TextureBrush(image1)
        texture.WrapMode = Drawing2D.WrapMode.Tile
        Dim formGraphics As Graphics = Me.CreateGraphics()
        formGraphics.FillEllipse(texture, _
            New RectangleF(90.0F, 110.0F, 100, 100))
        formGraphics.Dispose()

    Catch ex As System.IO.FileNotFoundException
        MessageBox.Show("There was an error opening the bitmap." _
            & "Please check the path.")
    End Try

End Sub

Remarks

Note

In .NET 6 and later versions, the System.Drawing.Common package, which includes this type, is only supported on Windows operating systems. Use of this type in cross-platform apps causes compile-time warnings and run-time exceptions. For more information, see System.Drawing.Common only supported on Windows.
