Flipping an Image

In This Topic

Bitmap lets you flip an image vertically as well as horizontally. To produce a flipped image using Bitmap, you can set the TransformOptions property of the FlipRotator class. The TransformOptions property can be set through TransformOptions enumeration in code.

The image below shows a horizontally-flipped image.

The following code illustrates flipping an image vertically or horizontally on button clicks. This example uses the sample created in the Quick start section.

Visual Basic
C#

Visual Basic

Private Sub ApplyTransform(t As BaseTransform)
    Dim newBitmap = bitmap.Transform(t)
    bitmap.Dispose()
    bitmap = newBitmap
    UpdateImage()
End Sub

'Event to flip the image vertically on button click
Private Sub Button_Click_1(sender As Object, e As RoutedEventArgs)
    ApplyTransform(New FlipRotator(TransformOptions.FlipVertical))
End Sub

'Event to flip the image horizontally on button click
Private Sub Button_Click_2(sender As Object, e As RoutedEventArgs)
    ApplyTransform(New FlipRotator(TransformOptions.FlipHorizontal))
End Sub

void ApplyTransform(BaseTransform t)
{
    var newBitmap = bitmap.Transform(t);
    bitmap.Dispose();
    bitmap = newBitmap;
    UpdateImage();
}

//Event to flip the image vertically on button click
private void Button_Click_1(object sender, RoutedEventArgs e)
{
    ApplyTransform(new FlipRotator(TransformOptions.FlipVertical));
}

//Event to flip the image horizontally on button click
private void Button_Click_2(object sender, RoutedEventArgs e)
{
    ApplyTransform(new FlipRotator(TransformOptions.FlipHorizontal));
}
