SilverSharp.CURVE_NODE

Structure

A SilverSharp.CURVE_NODE object stores information relevant to a SilverScreen spline or Bezier curve primitive

C# Code

class CURVE_NODE sealed : PRIM_NODE

{

CURVE_NODE(CURVE_NODE rhs);

CURVE_NODE(string curve_path);

readonly SURFACE_NODE sn;

readonly TEXTURE_DATA texture;

property SS_RGB surface_rgb { get; }

property uint surface_pattern_number { get; }

property SS_RGB curve_rgb { get; }

property WidthStyle curve_width_style { get; }

property PrimList Points { get; }

property PRIM_NODE first_point { get; }

};

Properties

The following read-only properties mimic the purpose of their counter-parts in the SilverC CURVE_NODE:

Name	Description
sn	A SURFACE_NODE reference, that if not null, stores the surface properties for rendering this primitive. When this member is null, then the surface properties from the parent OBJECT_NODE will be used to render this primitive.
texture	A TEXTURE_DATA reference, that if not null, stores the texture properties for rendering this primitive. When this member is null, then the texture properties from the parent OBJECT_NODE will be used to render this primitive.
surface_rgb	The fill color for closed spline and Bezier curves
surface_pattern_number	The surface pattern index for closed spline and Bezier curves, or 0 if there is none.
curve_width_style	The edge width and style index for rendering the curve.
curve_rgb	The edge color for rendering the curve.
first_point	The first primitive in the list of spline-point or Bezier-point primitives make up the control points of the curve. SilverSharp programmers might prefer using the Points enumerator

The following read-only properties extend CURVE_NODE for SilverSharp:

Name	Description
Points	Enumerates the list of spline-point or Bezier-point primitives that make up the control points of the curve.

Members

Member	Description
CURVE_NODE	Constructors to initialize the object

Remarks

A SilverSharp.CURVE_NODE inherits from a SilverSharp.PRIM_NODE and therefore includes those properties and methods as well; for instance, Path, Type, and PrimBits are inherited properties of a SilverSharp.PRIM_NODE.

A spline curve can be differentiated from a Bezier curve by checking the SilverSharp.PRIM_NODE properties IsSpline or IsBezier.

Note: A SilverSharp.CURVE_NODE is a SilverSharp.PRIM_NODE, but the reverse is not true.
