GdiGraphics.DrawBeziers Method (Pen, Point[])

Draws a sequence of connected Bezier splines.

Namespace: Aurigma.GraphicsMill.Drawing
Assembly: Aurigma.GraphicsMill (in Aurigma.GraphicsMill.dll)

Syntax

Visual Basic

Public Sub DrawBeziers ( _
	pen As Pen, _
	points As Point() _
)

C#

public void DrawBeziers(
	Pen pen,
	Point[] points
)

Parameters

pen: Type: Aurigma.GraphicsMill.Drawing.Pen
Pen object which is used to draw an spline.

points: Type: System.Drawing.Point []
Array of coordinates of the splines start, end, and control points.

Remarks

A single Bezier spline is defined with four points: first and last point specify beginning and end of the curve, second and third points specify so-called control points. The control points act as magnets, pulling the curve in certain directions to influence the way the Bezier spline bends.

The end point of each spline is a start point for the next one. So the points array should have at least 4 points and + 3 points for each extra spline.

All the coordinates are measured in units specified with Unit property.

Examples

Visual Basic

Dim bitmap As New Aurigma.GraphicsMill.Bitmap( _
 Aurigma.GraphicsMill.RgbColor.White, 185, 145, _
 Aurigma.GraphicsMill.PixelFormat.Format24bppRgb)

Dim graphics As Aurigma.GraphicsMill.Drawing.GdiGraphics = bitmap.GetGdiGraphics()

'Draw line
Dim pen As New Aurigma.GraphicsMill.Drawing.Pen(Aurigma.GraphicsMill.RgbColor.Red, 5)
graphics.DrawLine(pen, 10, 10, 100, 60)

'Draw polyline
pen.Color = Aurigma.GraphicsMill.RgbColor.FromArgb(150, 0, 255, 0)
pen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dash
pen.Width = 2
Dim points1 As System.Drawing.Point() = { _

 New System.Drawing.Point(180, 30), New System.Drawing.Point(80, 140)}
graphics.DrawLines(pen, points1)

'Draw beizer
pen.Color = Aurigma.GraphicsMill.RgbColor.Blue
