 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

```
Public Sub Glow ( _glowColor As Color, _intensity As Single, _radius As Single, _enlargeToFit As Boolean _
)
```
 
```csharp
public void Glow(Color glowColor,float intensity,float radius,bool enlargeToFit
)

### Parameters
 
 - glowColor
     - Type: [Aurigma.GraphicsMill.Color](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Color.htm.md)
Glow color.

 - intensity
     - Type: [System.Single](http://msdn2.microsoft.com/en-us/3www918f)
Positive [Single](http://msdn2.microsoft.com/en-us/3www918f) value that specifies glow intensity. Small values (about 1.0 or below) provide hardly visible glow. In the same time, large values (say, about 50) provide too heavy glow.

Value that specifies a blur radius used to blur the glow.

     - Type: [System.Boolean](http://msdn2.microsoft.com/en-us/a28wyd50)
Value that specifies whether to enlarge the image to fit entire glow.
 
## Remarks
  
You can also use [Glow](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_Glow.htm.md) class to apply this effect.
 
**Note** 
If the bitmap does not have an alpha channel (e.g. its pixel format is [Format24bppRgb](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_PixelFormat.htm.md)), alpha channel is automatically added. So be aware that pixel format of the output bitmap may differ from the input one.
