Applying Opacity in the code

[jjanguda]

Hi,

One of fellow members shared an indicator and I'm trying to add opacity inside this code. But I have no idea how... I want 50% of opacity of this vertical line. I would appreciate any suggestion. Thank you

protected override void OnBarUpdate()
{
if (Time[0].TimeOfDay.Minutes == 0 && (Time[0].TimeOfDay.Seconds == 00 ))
{

VerticalLine myLine1 = Draw.VerticalLine(this, "LineOnStart"+Time[0], 0, Brushes.White);
myLine1.Stroke = new Stroke(Brushes.DimGray, DashStyleHelper.Dot, 1);

}

Hello jjanguda,

Thanks for your post.

What I would suggest is to create a private brush variable at the class level, for example: private Brush myBrush = Brushes.DimGray;

To create the custom brush once, in State.DataLoaded:

Brush temp = myBrush.Clone(); // copy current brush
temp.Opacity = 50.0/100.0; // 50% opacity
temp.Freeze(); // required to freeze
myBrush = temp; // assign 50% opaque brush to user brush.

In OnBarUpdate() you would use myBrush where you are currently specifying a brush.

Note: The brush is created in state data loaded so that it is only created once.
