## Content

You will see a whitespace when the Form is maximized, but its zoomfactor is still 100%. You can set the Background color or Background image for the whitespace.
To set the Background color, you can use the **C1Zoom.BackColor** property like the following:
[C#]

```csharp
c1Zoom1.BackColor = Color.DarkGray;
```

[Visual Basic]

```vbnet
C1Zoom1.BackColor = Color.DarkGray
```

To set the Background image, you can use the **C1Zoom.BackgroundImage** property and the **C1Zoom.BackgroundImageLayout** property like the following:

[C#]

```csharp
c1Zoom1.BackgroundImage = new Bitmap("Background.png");  c1Zoom1.BackgroundImageLayout = ImageLayout.Tile;
```

[Visual Basic]

```vbnet
C1Zoom1.BackgroundImage = New Bitmap("Background.png")  C1Zoom1.BackgroundImageLayout = ImageLayout.Tile
```
