## Instruction

Write a C# program that reads an image in JPEG format and saves it as a PNG format image. The program should flip the image vertically before saving it.

## Usings

```csharp
using Aurigma.GraphicsMill.Transforms;
```

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Chicago.jpg"))
{
    bitmap.Transforms.Flip(FlipType.Vertical);
    bitmap.Save("WritePng.png");
}
```
