# RemoveAlpha Class
 
Removes the alpha channel from an image.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public sealed class RemoveAlpha : Transform
```
 
## Remarks
  
If the [BackgroundColor](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_RemoveAlpha_BackgroundColor.htm.md) property is null, the alpha channel is just discarded without affecting other channels. Otherwise the alpha channel is flattened using specified color (i.e. each pixel is alpha-blended with this color).
