DxPathBuilder

Full name Microsoft.VisualBasic.Drawing.DirectX.DxPathBuilder Assembly Microsoft.VisualBasic.Drawing.DirectX Members 13

The direct2d geometry constructor: converts the gdi+ style drawing primitive into a ID2D1Geometry object so that it can be rasterized by the gpu device.

01 Syntax

Microsoft.VisualBasic.Drawing.DirectX.DxPathBuilder

02 Methods

Name	Overloads	Summary
AddLines	1	append the polygon vertex buffer into the geometry sink, the vertex buffer is pinned during the call so that no extra copy is required.
AddTail	1	AddLines of the polygon, the first point is consumed by the BeginFigure call so that only the remaining points are appended here.
Polygon	1	build a polygon (or a polyline when closed is false)
Bezier	1	build a cubic bezier spline
Beziers	1	build a bezier spline sequence from a point array of 3n+1 points
GetArc	1	compute the arc segment of a gdi+ style arc: the angle unit is degree and the positive sweep angle goes clockwise on the screen.
Arc	1	build an open arc
Pie	1	build a pie shape: the center point, the arc and the closed outline
AddEllipseFigure	1	build an ellipse figure through two half arc segments
AddRectangleFigure	1	build a rectangle figure
CardinalSegments	1	convert the cardinal spline control points into a cubic bezier segment sequence
Curve	1	build a cardinal spline curve
FromGraphicsPath	1	replay the drawing operation sequence of a GraphicsPath object into a direct2d path geometry.

method AddLines #

AddLines(ID2D1GeometrySink, D2D1_POINT_2F(), Int32)

append the polygon vertex buffer into the geometry sink, the vertex buffer is pinned during the call so that no extra copy is required.

Parameters

Name	Type	Description
`offset`	`ID2D1GeometrySink`	the index of the first vertex that should be appended, the vertex before the offset is consumed by the BeginFigure call

method AddTail #

AddTail(ID2D1GeometrySink, D2D1_POINT_2F())

AddLines of the polygon, the first point is consumed by the BeginFigure call so that only the remaining points are appended here.

method Polygon #

Polygon(ID2D1Factory, D2D1_POINT_2F(), Boolean)

build a polygon (or a polyline when closed is false)

Curve(ID2D1Factory, D2D1_POINT_2F(), Single, Boolean)

build a cardinal spline curve

method FromGraphicsPath #

FromGraphicsPath(ID2D1Factory, GraphicsPath)

replay the drawing operation sequence of a GraphicsPath object into a direct2d path geometry.
