# Transparentize Class
 
Applies a transparentize effect to an image.
 
**Namespace:** [Aurigma.GraphicsMill.Transforms](https://www.graphicsmill.com/docs/gm/N_Aurigma_GraphicsMill_Transforms.htm.md)
 **Assembly:** Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)
 
## Syntax
  
```csharp
public sealed class Transparentize : MaskTransform
```
 
## Remarks
 This transform sets alpha values of pixels with a given color (and tolerant ones) to transparent. This transform is very useful when you need to blend two images and "upper" image does not have alpha channel, but it has a background color. For example, you draw a logo placed in the center of the image on white background. In this case you set [BackgroundColor](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_Transparentize_BackgroundColor.htm.md) to white color. You can also adjust a [Threshold](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_Transparentize_Threshold.htm.md) parameter to make colors close to white color semi-transparent (to get smooth colors). Besides of that [Threshold](https://www.graphicsmill.com/docs/gm/P_Aurigma_GraphicsMill_Transforms_Transparentize_Threshold.htm.md) is useful when background color is not completely uniform (for example, you loaded JPEG file with low quality).
