how to flip Image in wpf

Question

I recently learned how to rotate a BitmapImage using the \'TransformedBitmap\' and \'RotateTransformed\' classes. Now I am able to perform clockwise rotations on my images. But

Answer 1

Use a ScaleTransform with a ScaleX of -1 for horizontal and ScaleY of -1 for vertical flipping, applied to the image's RenderTransform property. Using RenderTransformOrigin="0.5,0.5" on the image makes sure your image gets flipped around its center, so you won't have to apply an additional TranslateTransform to move it into place:

for horizontal flipping and

for vertical.

If you want to do it in code-behind, in C# it should look something like this:

img.RenderTransformOrigin = new Point(0.5,0.5);
ScaleTransform flipTrans = new ScaleTransform();
flipTrans.ScaleX = -1;
//flipTrans.ScaleY = -1;
img.RenderTransform = flipTrans;
