SharpDX.Color

[TAJTrades]

In the code:
using(SharpDX,Direct2D1.SolidColorBrush dxBrush =
new SharpDX.Direct2D1.SolidColorBrush(Render Target, SharpDX.Color.Blue));

How would I set the color from a string such as "Blue" or "Systems.Window.Media.Colors Blue"

Something like:
SharpDX.Color = Color.Blue;

I am having a hard time finding info on SharpDX.

Thanks

Hello TAJTrades,

You could get this from a System.Windows.Media.Brush

For example:

SharpDX.Direct2D1.Brush myBrush = Brushes.Blue.ToDxBrush(RenderTarget);

Also, see my example of using these efficiently.

Edit:
I made an Indicator to simply things
In the OnRender it is throwing errors CS1502 and CS1503 on the line using......

I am trying to change the Help guide code from "SharpDX.Color.Blue" to "TestBrush.ToDxBrush(RenderTarget)". What am I doing wrong?

Hello TAJTrades,

What does the error message say?

The message is likely going to show you which line is causing the error.

[TAJTrades]

The error is on the line:
using (SharpDX.Direct2D1.SolidColorBrush dxBrush = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, TestBrush.ToDxBrush(RenderTarget)))

Error Messages:
#1
TJBrushOnRenderTest.cs,The best overloaded method match for 'SharpDX.Direct2D1.SolidColorBrush.SolidColorBrush (SharpDX.Direct2D1.RenderTarget SharpDX.Color4)' has some invalid arguments,CS1502,62,57,
#2
TJBrushOnRenderTest.cs,Argument 2: cannot convert from 'SharpDX.Direct2D1.Brush' to 'SharpDX.Color4',CS1503,62,109,

So I am thinking the error happens trying to convert Brush TestBrush to ToDxBrush

[NinjaTrader_ChelseaB]

Hello TAJTrades,

I am not understanding what the using call is for..

I unsure of how this will affect things.

I am also unsure how you are trying to create a new SharpDX.Direct2D1.SolidColorBrush using a SharpDX.Direct2D1.Brush as the parameter.

When you call TestBrush.ToDxBrush(RenderTarget) this is going to return a SharpDX.Direct2D1.Brush which is already a usable brush. (Please take a look at the example I provided you)
You are trying to take this usable brush and supply this as a parameter to the constructor of SharpDX.Direct2D1.SolidColorBrush. A SharpDX.Direct2D1.SolidColorBrush will not accept a SharpDX.Direct2D1.Brush as a parameter. The constructor for this object will only accept a Color4 object.

http://ninjatrader.com/support/helpGuides/nt8/en-us/sharpdx_color4.htm

But I can say that the following would work:

SharpDX.Direct2D1.Brush dxBrush = TestBrush.ToDxBrush(RenderTarget);

[TAJTrades]

Wow, I never imagined this could be so difficult.

The using statement is copied for the Help Guide. Seach Help Guide for OnRender, result #1. It is the exact code I pasted in my post #3.

using(SharpDX.Direct2D1.SolidColorBrushdxBrush=newSharpDX.Direct2D1.SolidColorBrush(RenderTarget,Sha rpDX.Color.Blue))
{
RenderTarget.FillRectangle(newSharpDX.RectangleF(ChartPanel.X,ChartPanel.Y,Chart Panel.W,ChartPanel.H),dxBrush);
}

Now in that using statement, at the end is "SharpDX.Color.Blue"

All I am trying to do is get a code snippet that is not hard coded for a color, in this case DodgerBlue. So I tired replacing (NOTE: Bold, Italic, Under Line area):

using(SharpDX.Direct2D1.SolidColorBrushdxBrush=newSharpDX.Direct2D1.SolidColorBrush(RenderTarget,SharpDX.Color.Blue))

with

using(SharpDX.Direct2D1.SolidColorBrushdxBrush=newSharpDX.Direct2D1.SolidColorBrush(RenderTarget,TestBrush.ToDXBrush(RenderTarget))

it throws an error. Why? How can I fix that. I prefer to use the "using" method as that is supposed to take care of the cleanup/ dispose.

[NinjaTrader_ChelseaB]

Hello TAJTrades,

Thank you for pointing out this error in the help guide.

http://ninjatrader.com/support/helpGuides/nt8/en-us/onrender.htm

I have notified our product management of the incorrect code so that this may be corrected.

You are getting an error because this object's constructor will not accept a SharpDX.Direct2D1.Brush as a parameter. It will only accept a SharpDX.Direct2D1.Color4 as a parameter.

[TAJTrades]

Ok, making progress. I can accept the error in the Help Guide.

That creates a new question. Can I convert this TestBush to SharpDX.Direct2D1.Color4

if (State == State.SetDefaults)
            {
              TestBrush  = Brushes.Orange;
            }


#region Properties
        [NinjaScriptProperty]
        [XmlIgnore]
        [Display(Name="TestBrush", Description="TestBrush Description", Order=1, GroupName="Parameters")]
        public Brush TestBrush
        { get; set; }

        [Browsable(false)]
        public string TestBrushSerializable
        {
            get { return Serialize.BrushToString(TestBrush); }
            set { TestBrush = Serialize.StringToBrush(value); }
        }            
        #endregion

If so how? Keep in mind I prefer to us the "using" method. The Color4 in the Help Guide leaves me lost. I am not sure what to do with the constructor Color4().

I have now found 2 issues in the Help Guide so I am a little hesitant to lean on it to hard. Thanks for your help. I am really not trying to be a PITA.

[NinjaTrader_ChelseaB]

Hello TAJTrades,

You would need to do this from the argb of the System.Windows.Media.SolidColorBrush.Color property.

Color4(float red, float green, float blue, float alpha)
https://msdn.microsoft.com/en-us/lib...v=vs.110).aspx
http://ninjatrader.com/support/helpG...pdx_color4.htm

SolidColorBrush testSolidColorBrush = (SolidColorBrush)TestBrush;

SharpDX.Color4 color4Obj = new SharpDX.Color4(testSolidColorBrush.Color.R, testSolidColorBrush.Color.G, testSolidColorBrush.Color.B, testSolidColorBrush.Color.A);

Thank you ChelseaB. This was very helpful for an issue I was working on just now!
