Parameters

ImageID: GdPicture image identifier.
DstLeft: Specifies the x-coordinate of the upper-left corner of the rectangle that bounds the ellipse.
DstTop: Specifies the y-coordinate of the upper-left corner of the rectangle that bounds the ellipse.
Width: Specifies the width of the rectangle that bounds the ellipse.
Height: Specifies the height of the rectangle that bounds the ellipse.
FillColor: Color of the filled ellipse.
AntiAlias: Set to True to apply the Antialiasing algorithm else False.

Return Value

A member of the GdPictureStatus enumeration.

Example

Filling a blue ellipse with a center at 200, 200 with the horizontal radius 150 pixels and the vertical radius 100 pixels.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int centerX = 200, centerY = 200, horizontalRadius = 150, verticalRadius = 100;
    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, gdpictureImaging.ARGB(0, 0, 0, 0));
 
    // Fill the ellipse. The AntiAlias parameter is set to true to apply antialiasing algorithm, i.e. to improve the appearance of the ellipse boundary.
    gdpictureImaging.DrawFilledEllipse(imageID, centerX, centerY, horizontalRadius, verticalRadius, gdpictureImaging.ARGB(255, 0, 0, 255), true);
 
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
