# ChannelsProvider Class
 
This class contains methods and properties used by [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) to provide access to bitmap channels.
 
**Namespace:** [Aurigma.GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
<DefaultMemberAttribute("Channel")> _
Public Class ChannelsProvider _Inherits LockableObject
```
 
```csharp
[DefaultMemberAttribute("Channel")]
public class ChannelsProvider : LockableObject
```
 
## Remarks
 This class enables you to extract bitmap channels to separate grayscale image, or replace some channel with another grayscale bitmap. You can do that using [Channel\[Int32\]](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_ChannelsProvider_Channel_1_e1836fc4.htm.md) method. Here you can add alpha channel ([AddAlpha(Single)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_ChannelsProvider_AddAlpha_1_7a94462e.htm.md) method) or remove it ([DiscardAlpha(Color)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_ChannelsProvider_DiscardAlpha_1_929597d9.htm.md) method). Using [Transparentize(Color, Single)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_ChannelsProvider_Transparentize_2_d079cd70.htm.md) method you can make alpha channel transparent at the areas with specified color.
