Parameters

ImageID: GdPicture image identifier.
Angle: Angle of rotation in degrees.
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 rectangle. A suitable color value can be obtained by using the ARGB() method.
AntiAlias: Set to True to apply the Antialiasing algorithm else False.

Return Value

A member of the GdPictureStatus enumeration.

This method requires the Image Documents component to run.

Filling a rotated ellipse on a GdPicture image.

C#

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int left = 50, top = 100, width = 250, height = 150;
    float angle = 30.0f;
    Color fillColor = Color.Green;
    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, Color.White);
 
    // Fill the rotated ellipse. The AntiAlias parameter is set to true to apply antialiasing algorithm, i.e. to improve the appearance of the ellipse boundary.
    gdpictureImaging.DrawRotatedFilledEllipse(imageID, angle, left, top, width, height, fillColor, true);
 
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
