# AddNoise Constructor (Single, DistributionKind, Boolean, Int32)
 
Creates new [AddNoise](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_AddNoise.htm.md) class instance. You can specify all the transform parameters here (noise amount, distribution kind, seed, and if it should be gray). Transform will be applied to all channels of the bitmap.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public Sub New ( _amount As Single, _distributionKind As DistributionKind, _grayNoise As Boolean, _seed As Integer _
)
```
 
```csharp
public AddNoise(float amount,DistributionKind distributionKind,bool grayNoise,int seed
)
```
 
### Parameters
 
 - amount
     - Type: [System.Single](http://msdn2.microsoft.com/en-us/3www918f)
Noise amount value varying in range [-1, 1]. You can change this value later through property [Amount](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_AddNoise_Amount.htm.md).

 - distributionKind
     - Type: [Aurigma.GraphicsMill.Transforms.DistributionKind](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_DistributionKind.htm.md)
A member of [DistributionKind](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_DistributionKind.htm.md) enumeration specifying noise distribution law. You can change this value later through property [DistributionKind](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_AddNoise_DistributionKind.htm.md).

 - grayNoise
     - Type: [System.Boolean](http://msdn2.microsoft.com/en-us/a28wyd50)
A value specifying if to generate gray or color noise. You can change this value later through property [GrayNoise](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_AddNoise_GrayNoise.htm.md).

 - seed
     - Type: [System.Int32](http://msdn2.microsoft.com/en-us/td2s409d)
An integer value specifying seed for random generator. You can change this value later through property [Seed](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_AddNoise_Seed.htm.md).
