GdiGraphics.FillEllipse Method (Brush, Int32, Int32, Int32, Int32)

Fills an ellipse.

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

Syntax

Visual Basic

Public Sub FillEllipse ( _
	brush As Brush, _
	x As Integer, _
	y As Integer, _
	width As Integer, _
	height As Integer _
)

C#

public void FillEllipse(
	Brush brush,
	int x,
	int y,
	int width,
	int height
)

Parameters

brush: Type: Aurigma.GraphicsMill.Drawing.Brush
Brush object which is used to fill an ellipse.

x: Type: System.Int32
X-coordinate of the top left corner of the bounding rectangle for the ellipse.

y: Type: System.Int32
Y-coordinate of the top left corner of the bounding rectangle for the ellipse.

width: Type: System.Int32
Width of the bounding rectangle for the ellipse.

height: Type: System.Int32
Height of the bounding rectangle for the ellipse.

Remarks

Ellipse is defined by its tightest bounding rectangle. If you have an ellipse defined with central point and two radiuses, you can convert these parameters to rectangle in the following way:

C#


// Let's assume we have centerX, centerY - coordinates of the ellipse center, 
// horizontalRadius and verticalRadius - radiuses of the ellipse.
// We are calculating rectX, rectY, rectWidth, and rectHeight which specify 
// bounding rectangle for ellipse.

rectX = centerX - horizontalRadius;
rectY = centerY - verticalRadius;
rectWidth = horizontalRadius * 2;
rectHeight = verticalRadius * 2;

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

To outline an ellipse, use DrawEllipse(Pen, Int32, Int32, Int32, Int32) 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)
