# BmpFrame Class
 
This class represents a frame of the BMP format.
 
**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 NotInheritable Class BmpFrame _Inherits Frame
```
 
```csharp
public sealed class BmpFrame : Frame
```
 
## Examples
  
You can use [BmpWriter](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_BmpWriter.htm.md) class instead of the [Save(String, IEncoderOptions)](https://www.graphicsmill.com/docs/gm5/M_Aurigma_GraphicsMill_Bitmap_Save_2_b73a8298.htm.md) method of the [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md). In particular it enables you to save the image asynchronously.
 
The [BmpWriter](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_BmpWriter.htm.md) class usage is demonstrated below:
 
```
Dim bitmap As New Aurigma.GraphicsMill.Bitmap("c:\Mountain.jpg")

Dim writer As New Aurigma.GraphicsMill.Codecs.BmpWriter("C:\Mountain.bmp")

Dim frame As New Aurigma.GraphicsMill.Codecs.BmpFrame( _
    Aurigma.GraphicsMill.Codecs.CompressionType.None)

frame.SetBitmap(bitmap)

bitmap.Dispose()

writer.AddFrame(frame)

frame.Dispose()

writer.Dispose()
```
 
```csharp
using (Aurigma.GraphicsMill.Bitmap bitmap = 
           new Aurigma.GraphicsMill.Bitmap(@"c:\Mountain.jpg"))
{
    using (Aurigma.GraphicsMill.Codecs.BmpWriter writer = 
        new Aurigma.GraphicsMill.Codecs.BmpWriter())
    {
        writer.Open(@"C:\Mountain.bmp");

        using (Aurigma.GraphicsMill.Codecs.BmpFrame frame = 
                   new Aurigma.GraphicsMill.Codecs.BmpFrame())
        {
            frame.Compression = Aurigma.GraphicsMill.Codecs.CompressionType.None;
            frame.SetBitmap(bitmap);

            writer.AddFrame(frame);
        }
    }
}
```
