Disclaimer: The SharpDX SDK Reference section was compiled from the official SharpDX Documentation and was NOT authored by NinjaTrader.  The contents of this section are provided as-is and only cover a fraction of what is available from the SharpDX SDK.  This page was intended only as a reference guide to help you get started with some of the 2D Graphics concepts used in the NinjaTrader.Custom assembly.  Please refer to the official SharpDX Documentation for additional members not covered in this reference.  For more seasoned graphic developers, the original MSDN Direct2D1 and DirectWrite unmanaged API documentation can also be helpful for understanding the DirectX/Direct2D run-time environment. For NinjaScript development purposes, we document only essential members in the structure of this page.




Defines an object that paints an area. Interfaces that derive from Brush describe how the area is painted.

1.An Brush is a device-dependent resource: your application should create brushes after it initializes the render target with which the brush will be used, and recreate the brush whenever the render target needs recreated. Please see the MSDN Direct2D Resources Overview for more information.

2.Brush space in Direct2D is specified differently than in XPS and Windows Presentation Foundation (WPF). In Direct2D, brush space is not relative to the object being drawn, but rather is the current coordinate system of the render target, transformed by the brush transform, if present. To paint an object as it would be painted by a WPF brush, you must translate the brush space origin to the upper-left corner of the object's bounding box, and then scale the brush space so that the base tile fills the bounding box of the object.

3.For convenience, Direct2D provides the BrushProperties function for creating new a Brush.

1.For NinjaScript Development purposes, you can use the NinjaTrader.Gui.DxExtensions.ToDxBrush() helper method to convert a System.Windows.Media.Brush to a SharpDX.Direct2D1.Brush s

2.General information on Direct2D brushes can be found on the MSDN Direct2D Brushes Overview
