Brush to SharpDx.color

[Bidder]

Hi

I have a brush property and I need to find a way to convert it to a SharpDx.Color.
Below is the brush property and below that is the code from OnRender. Right now the color is hardcoded as Yellow.
The object is to replace the hard coded color with the brush color.
Hopefully this makes sense.

[Display(Name="speed color", Order=1, GroupName="Parameters")]
public Brush TapeSpeedLowColor
{ get; set; }

SharpDX.Color dxColor = SharpDX.Color.Yellow;
SharpDX.Direct2D1.SolidColorBrush solidDXBrush = new SharpDX.Direct2D1.SolidColorBrush(RenderTarget, dxColor);
RenderTarget.FillRectangle(rect2, solidDXBrush);

Hello Bidder,

Thanks for your post.

You would need to create a SharpDX.Direct2D1.Brush and assign the user-defined brush to that SharpDX brush. For example, if we have a user-defined brush called TextBrush, we would need to assign that to our SharpDX.Direct2D1.Brush. See below.

//In OnRender()
SharpDX.Direct2D1.Brush textBrushDx;

textBrushDx = TextBrush.ToDxBrush(RenderTarget);

Please see the attached example script which demonstrates using a user-defined brush property for SharpDX rendering.

Also, see the help guide documentation linked below for more information.

Hi Brandon, Thank you for this information, working smoothly thanks to your help.

Mr. SharpDX and I have had brief, one-sided conversations on many occasions. Brief, primarily because all the words contain only 4 letters. : )

Just for anyone that still looking at this solution, beware - the ToDxBrush() extension is not thread-safe and it will throw an exception if trying to access the system brush inside of a OnRender() method.

Hello TuffWeasel,

Welcome to the NinjaTrader forums!

The ToDxBrush() is dependent on the RenderTarget. You will not be able to use .ToDxBrush() outside of OnRender() or OnRenderTargetChanged().

Below is a link to the help guide.

https://ninjatrader.com/support/helpGuides/nt8/dxextensions_todxbrush.htm

Included with NinjaTrader is the SampleCustomRender indicator that demonstrates on line 127 using .ToDxBrush() in OnRender().

Also, below is a link to another example.
