Example

How to obtain the proper value for the red color.

VB.NET
C#

'We assume that the GdViewer1 control has been properly integrated.

            

'Get the value for the red color.

Dim colorRed As Integer = GdViewer1.ARGBI(255, 255, 0, 0)

'Set the new background color.

GdViewer1.SetBackgroundColor(colorRed)

//We assume that the GdViewer1 control has been properly integrated.

            

//Get the value for the red color.

int colorRed = GdViewer1.ARGBI(255, 255, 0, 0);

//Set the new background color.

GdViewer1.SetBackgroundColor(colorRed);
