Changing OutlineStroke opacity

[xsgex]

How does one change the opacity of the OutlineStroke?

This does not work, because Pen is read-only:

rectangle.OutlineStroke.Pen.Opacity = 0.5

Hello,

Thank you for the post.

For the overloads that you can pass a Brush to, you could use a SolidColorBrush which allows for an opacity. You could pass a SolidColorBrush to the "Brush" overload for this to affect the Outline.

Brush b = new SolidColorBrush(Color.FromRgb(255,0,0));
b.Opacity = 0.3;
b.Freeze();
Rectangle rectangle = Draw.Rectangle(this, "Rect", 1, Close[1], 0, Close[0], b);

For the OutlineStroke specifically after you have already drawn the object you could also use the following approach:

Rectangle rectangle = Draw.Rectangle(this, "Rect", 1, Close[1], 0, Close[0], Brushes.Red);

Brush b = new SolidColorBrush(Color.FromRgb(0,0,0));
b.Opacity = 0.3;
b.Freeze();

Stroke s =  new Stroke(b, 3);
rectangle.OutlineStroke = s;

I look forward to being of further assistance.
