# BmpEncoderOptions Class
 
This class holds possible BMP format encoder options.
 
**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 BmpEncoderOptions _Inherits EncoderOptions
```
 
```csharp
public sealed class BmpEncoderOptions : EncoderOptions
```
 
## Remarks
  
When you save image to BMP you can specify the single BMP-related setting: compression type (using [Compression](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Codecs_BmpEncoderOptions_Compression.htm.md) property).
 
**Note** 
BMP supports only RLE compression for 4-bit and 8-bit images.
 
[MediaFormat](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Codecs_EncoderOptions_MediaFormat.htm.md) property of this class always returns value that equals to [BmpFormat](https://www.graphicsmill.com/docs/gm5/F_Aurigma_GraphicsMill_Codecs_FormatManager_BmpFormat.htm.md) static field of the [FormatManager](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Codecs_FormatManager.htm.md) class. [Left](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Codecs_EncoderOptions_Left.htm.md) and [Top](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Codecs_EncoderOptions_Top.htm.md) are meaningless for BMP and always set to 0.
 
## Examples
  
This sample saves the BMP image with RLE compression:
 
```
Dim bitmap As New Aurigma.GraphicsMill.Bitmap("c:\Mountain.gif")

bitmap.Save("C:\Mountain.bmp", New Aurigma.GraphicsMill.Codecs.BmpEncoderOptions( _
    Aurigma.GraphicsMill.Codecs.CompressionType.Rle))

bitmap.Dispose()
```
 
```csharp
using (Aurigma.GraphicsMill.Bitmap bitmap = 
           new Aurigma.GraphicsMill.Bitmap(@"C:\Mountain.gif"))
{
    bitmap.Save(@"C:\Mountain.bmp", new Aurigma.GraphicsMill.Codecs.BmpEncoderOptions(
        Aurigma.GraphicsMill.Codecs.CompressionType.Rle));
}
```
