Visual Basic (Declaration) 
Public Overridable Property TransparencyColor As Color
Visual Basic (Usage)Copy Code
Dim instance As Picture
Dim value As Color
instance.TransparencyColor = value
value = instance.TransparencyColor
public virtual Color TransparencyColor {get; set;}

Property Value

Color object containing the color


Use this property to specify the transparency color for the picture. When you set a transparency color, the background behind the picture shows through the pictures in the area that originally had the color you specify. For example, if you specify yellow as the transparency color, areas in the picture that are yellow appear transparent, and the area behind them shows through the picture. Icon files (*.ico) do not support TransparencyColor when loaded into FarPoint.Win.Picture.

Specify the picture to display by setting the Image property.

Specify the range of values considered transparent by using the TransparencyTolerance property.


This example draws a picture in the top left of the dialog.
