# JpegFrame.ChromaSubsamplingEnabled Property 
 
Gets/sets the value that specifies whether to use chroma subsampling in JPEG compression or not.
 
**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 Property ChromaSubsamplingEnabled As Boolean
```
 
```csharp
public bool ChromaSubsamplingEnabled { get; set; }
```
 
### Property Value
Value that specifies whether to use chroma subsampling in JPEG compression or not.
 
## Remarks
  
Chroma subsampling is one of the compression methods used in JPEG. It is based on the specific of the human vision and allows to reduce size of the result file by storing color information at lower resolution than luminance information. In most cases this tradeoff will not be noticeable to the human. But sometimes such information loss may be significant (e.g. for some classes of image processing algorithms) and chroma subsampling should be turned off.
 
Chroma subsampling is enabled by default.
