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

Property Value

Integer number between 0 and 255 representing the transparency tolerance


The value of the tolerance should be between 0 and 255. 

The transparency tolerance determines how close the red, green, and blue components of a color must be to the TransparencyColor to be transparent in the rendered image. For example, if the TransparencyColor is Color.White (255,255,255) and the TransparencyTolerance is 1, then the color (254,254,254) is also rendered transparent.


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