IRenderContext2D Interface Members
The following tables list the members exposed by IRenderContext2D.
Public Properties
Name | Description | |
---|---|---|
Layers | Gets a collection of RenderOperationLayers, which allow rendering operations to be posted to a layered queue for later execution in order (and correct Z-ordering). | |
ViewportSize | Gets the current size of the viewport. |
Public Methods
Name | Description | |
---|---|---|
AsExtremeRenderContext | Gets IExtremeRenderContext2D from this render context | |
BeginLine | Begins a Polyline segment, returning the IPathDrawingContext. This is the fastest way to draw lines and simply a proxy to DrawLines method. | |
BeginPolygon | Begins a filled Polygon segment, returning the IPathDrawingContext. This is the fastest way to draw polygon and simply a proxy to FillArea method. | |
BeginSpriteBatch | Begins a Sprite Batch, returning the IPathDrawingContext. This is the fastest way to draw sprites and simply a proxy to %RenderContextBase.DrawSprites(ISprite2D, Rect, IEnumerable<Point>)% method. | |
Clear | Clears the IRenderSurface2D | |
CreateBrush | Overloaded. Creates a IBrush2D valid for the current render pass. Use this to draw rectangles, polygons and shaded areas | |
CreatePen | Creates a IPen2D valid for the current render pass. Use this to draw outlines, quads and lines | |
CreateSprite | Overloaded. Creates a Sprite from FrameworkElement by rendering to bitmap. This may be used in the DrawSprite method to draw to the screen repeatedly | |
CreateTexture | Creates a Texture with the specified width, height and format. This texture may be modified, and drawn repeatedly using %DrawTexture(ITexture2D, Rect)% | |
Dispose | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from System.IDisposable) | |
DisposeResourceAfterDraw | Call this method, passing in System.IDisposable instance to dispose after the render pass completes. Called internally by SciChart to lazy-dispose of Direct2D and Direct3D brushes and textures | |
DrawEllipse | Draws an Ellipse on the IRenderSurface2D using the specified outline Pen and fill Brush | |
DrawEllipses | Draws 0..N Ellipses at the points passed in with the same width, height, pen and brush | |
DrawHeightTextureContours | Draws contours for a height texture the texture. | |
DrawLine | Draws a single line on the IRenderSurface2D using the specified IPen2D. Note for a faster implementation in some rasterizers, use DrawLines passing in an IEnumerable | |
DrawLines | Draws a multi-point line on the IRenderSurface2D using the specified IPen2D | |
DrawPixelsVertically | Overloaded. Draws vertical scan line for heatmap from bottom to top, from yStart to yEnd | |
DrawQuad | Draws a Quad on the IRenderSurface2D using the specified IPen2D | |
DrawSprite | Blits the source image onto the IRenderSurface2D | |
DrawSprites | Overloaded. Batch draw of the source sprite onto the IRenderSurface2D | |
DrawText | Overloaded. Draws text at the specified position | |
DrawTexture | Draws the ITexture2D to the specified viewport rect | |
FillArea | Fills an area defined the the Points and Heights, e.g. as in a mountain chart, using the specifie IBrush2D | |
FillPolygon | Fills a polygon on the IRenderSurface2D using the specifie IBrush2D | |
FillRectangle | Overloaded. Fills a rectangle on the IRenderSurface2D using the specified IBrush2D | |
IsCompatibleType<T> | Determines whether the primitive type T is compatible with this IRenderContext2D instance | |
MeasureText | Measures text | |
SetPrimitivesCachingEnabled | Enables or disables primitves caching optimization (Direct3D renderer only) |
Extension Methods
Name | Description | |
---|---|---|
GetStyledPen | Takes a System.Windows.Shapes.Line with a System.Windows.Style applied, and returns a SciChart compatible SciChart.Drawing.Common.IPen2D which can be used with the SciChart.Drawing.Common.IRenderContext2D for drawing lines | |
SafeDispose | Checks for null and if not null, calls Dispose |
