How do I get RGBA from a Stroke?

[ETFVoyageur]

Stroke has a Brush, but that is the base class Brush, and so does not have a Color property. Same goes for Stroke.Pen. So how do I extract RGBA from a Stroke object?

Is it useful for a Stroke to take any kind of Brush, or should that be a SolidColorBrush? (I do not really know all of the places a Stroke is used.)

This question is just to see whether I am missing something. In my own code I can just always construct a Stroke with a SolidColorBrush, and the cast it back when I need to retrieve it.

DrawingAttributes property.

DrawingAttributes property.

Intellisense says that Stroke does not have a DrawingAttributes property.

Are you using the Microsoft.Ink namespace, and have you referenced the microsoft.ink.dll?

In the System.Windows.Media namespace, only a SolidColorBrush will give you a color property. Stroke just takes a Brush which could use any type of brush to fill an area (LinearGradientBrush, etc).

So to get the Color RGB from a Stroke, you can cast myStroke.Brush as a SolidColorBrush in order to get the Color property.

//NinjaTrader.Gui.Stroke from System.Windows.Media.Brushes
Stroke myStroke = new Stroke(Brushes.Orchid);

// System.Windows.Media.Color from Gui.Stroke.Brush as System.Windows.Media.SolidColorBrush
Color myColor = ((SolidColorBrush)myStroke.Brush).Color;

//	byte a = myColor.A;
//	byte r = myColor.R;
//	byte g = myColor.G;
//	byte b = myColor.B;

// create new System.Windows.Media.SolidColorBrush System.Windows.Media.Color.FromArgb();
SolidColorBrush newBrush = new SolidColorBrush(Color.FromArgb(myColor.A, myColor.R, myColor.G, myColor.B));

Print(newBrush.Color);

Ignore me. That is Stroke from a different namespace. My mistake. I apologize.

Thanks folks. It sounds as if you are confirming that there is no better plan than the one from my original message: ensure that the Stroke is created with a SolidColorBrush and then cast as needed when it comes time to retrieve the RGBA.
