# Bitmap.Changed Event
 
Fires when the bitmap was modified (after the end of an operation).
 
**Namespace:** [Aurigma.GraphicsMill](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Protected Event Changed As BitmapChangedEventHandler
```
 
```csharp
protected event BitmapChangedEventHandler Changed
```
 
## Remarks
  
This event is fired only if you run the operations through build-in methods or properties. If you create external transform or codec and run it, this event will not fire (in this case you should use [Stopped](https://www.graphicsmill.com/docs/gm5/E_Aurigma_GraphicsMill_ISyncEvents_Stopped.htm.md) event of the transform or codec you create).
