GdiGraphics.DrawPolygon Method (Pen, Point[])

Draws a polygon.

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

Syntax

Visual Basic

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

C#

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

Parameters

pen: Type: Aurigma.GraphicsMill.Drawing.Pen
Pen object which is used to outline a polygon.

points: Type: System.Drawing.Point []
Array of coordinates of the polygon vertices.

Remarks

Polyline can be treated as closed polyline, where last point is connected with the first one.

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

To fill the polygon, use FillPolygon(Brush, Point[], FillMode) method.

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 filled and outlined rectangle
Dim pen As New Aurigma.GraphicsMill.Drawing.Pen(Aurigma.GraphicsMill.RgbColor.Red, 3)
Dim brush As New Aurigma.GraphicsMill.Drawing.SolidBrush( _
 Aurigma.GraphicsMill.RgbColor.FromRgb(&HDD, &HDD, &HFF))
graphics.FillRectangle(brush, 10, 10, 100, 60)
graphics.DrawRectangle(pen, 10, 10, 100, 60)

'Draw filled but non-outlined ellipse
brush.Color = Aurigma.GraphicsMill.RgbColor.Yellow
graphics.FillEllipse(brush, 60, 40, 100, 80)

'Draw outlined but non-filled polygon 
pen.Color = Aurigma.GraphicsMill.RgbColor.Green
pen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot
pen.Width = 1
Dim points As System.Drawing.Point() = { _
 New System.Drawing.Point(20, 30), New System.Drawing.Point(50, 2), _
 New System.Drawing.Point(180, 30), New System.Drawing.Point(80, 140)}
graphics.DrawPolygon(pen, points)
