# PreLoadedFrame Class
 
This class represents a frame returned by [FormatReader](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_FormatReader.htm.md) and always containing a bitmap.
 
**Namespace:** [Aurigma.GraphicsMill.Codecs](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Codecs.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```
Public MustInherit Class PreLoadedFrame _Inherits Frame
```
 
```csharp
public abstract class PreLoadedFrame : Frame
```
 
## Remarks
  
This abstract class is used for reading unseekable movies and, therefore, such kind of frames should already contain a bitmap, in contrast to the [Frame](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_Frame.htm.md) objects.
