Examples

The following code example is designed for use with Windows Forms. It is a handler for the Paint event. A Graphics object is passed to the event and is used to draw the image on the form. The code performs the following actions:

  • Creates an image from a file named SampImag.jpg. This file must be located in the same folder as the application executable file.

  • Creates a point at which to draw the upper-left corner of the image.

  • Draws the unscaled image on the form.

Visual Basic
Private Sub ImageExampleForm_Paint _
    (ByVal sender As System.Object, _
    ByVal e As System.Windows.Forms.PaintEventArgs) _
    Handles MyBase.Paint


    ' Create image.
    Dim newImage As Image = Image.FromFile("SampImag.jpg")

    ' Create Point for upper-left corner of image.
    Dim ulCorner As New Point(100, 100)

    ' Draw image to screen.
    e.Graphics.DrawImage(newImage, ulCorner)
End Sub
C#
private void ImageExampleForm_Paint(object sender, PaintEventArgs e)
{         
    // Create image.
    Image newImage = Image.FromFile("SampImag.jpg");

    // Create Point for upper-left corner of image.
    Point ulCorner = new Point(100, 100);

    // Draw image to screen.
    e.Graphics.DrawImage(newImage, ulCorner);
}
Visual C++
private:
   void ImageExampleForm_Paint(System::Object^  sender, System::Windows::Forms::PaintEventArgs^  e) 
   {
      // Create image.
      Image^ newImage = Image::FromFile( "SampImag.jpg" );

      // Create Point for upper-left corner of image.
      Point ulCorner = Point(100,100);

      // Draw image to screen.
      e->Graphics->DrawImage( newImage, ulCorner );
   }
