IRenderContext2D

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).

Gets the current size of the viewport.

Begins a Polyline segment, returning the IPathDrawingContext. This is the fastest way to draw lines and simply a proxy to Point}) method.

pen

The pen for the line segment

startX

The start X coordinate (pixel coord)

startY

The start Y coordinate (pixel coord)

戻り値: The IPathDrawingContext to continue the line

Begins a filled Polygon segment, returning the IPathDrawingContext. This is the fastest way to draw polygon and simply a proxy to Double) method.

brush

The brush for the polygon fill

startX

The start X coordinate (pixel coord)

startY

The start Y coordinate (pixel coord)

gradientRotationAngle

The angle which the brush is rotated by

戻り値: The IPathDrawingContext to continue the polygon

Clears the IRenderSurface2D

Creates a IBrush2D valid for the current render pass. Use this to draw rectangles, polygons and shaded areas

color

The color of the brush, supports transparency

opacity

The opacity of the brush

alphaBlend

If true, use alphablending when shading. If null, auto-detect

戻り値: The IBrush2D instance

Creates a IBrush2D from WPF Brush valid for the current render pass. Use this to draw rectangles, polygons and shaded areas

brush

The WPF Brush to use as a source, e.g. this can be a , or it can be a . Note that solid colors support transparency and are faster than gradient brushes

opacity

The opacity of the brush

textureMappingMode

Defines a TextureMappingMode, e.g. brushes share a texture per viewport or a new texture per primitive drawn

戻り値: The IBrush2D instance

Creates a IPen2D valid for the current render pass. Use this to draw outlines, quads and lines

color

The color of the pen, supports transparency

antiAliasing

If true, use antialiasing

strokeThickness

The strokethickness, default=1.0

opacity

The opecity of the pen

strokeDashArray

strokeEndLineCap

戻り値: The IPen2D instance

Creates a Sprite from FrameworkElement by rendering to bitmap. This may be used in the Point) method to draw to the screen repeatedly

fe

max digit size in pixels

Call this method, passing in IDisposable instance to dispose after the render pass completes. Called internally by Ultrachart to lazy-dispose of Direct2D and Direct3D brushes and textures

disposable

Draws 0..N Ellipses at the points passed in with the same width, height, pen and brush

strokePen

fillBrush

centres

The points to draw ellipses at

width

The common width for all ellipses

height

The common height for all ellipses

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

pen

The pen

pt1

The start of the line in pixels

pt2

The end of the line in pixels

Draws a multi-point line on the IRenderSurface2D using the specified IPen2D

pen

The pen

points

The points

戻り値: The last point in the polyline drawn

Draws vertical scan line for heatmap from bottom to top, from yStart to yEnd

x

Screen X coordinate where to draw pixels

yStartBottom

Screen Y coordinate of vertical scan line's bottom. Can be located outdide of visible area, in this case not all pixels in list are rendered

yEndTop

Screen Y coordinate of vertical scan line's top. Can be located outdide of visible area, in this case not all pixels in list are rendered

pixelColorsArgb

The list of pixel colors to draw

opacity

The Opacity of the line from 0.0 to 1.0

yAxisIsFlipped

if set to true then y axis is flipped.
