GdPicture14 Namespace / GdPictureImaging Class / DrawRotatedEllipse Method / DrawRotatedEllipse(Int32,Single,Single,Single,Single,Single,Single,Int32,Boolean) Method
GdPicture image identifier.
Angle of rotation in degrees.
Specifies the x-coordinate of the upper-left corner of the rectangle that bounds the ellipse.
Specifies the y-coordinate of the upper-left corner of the rectangle that bounds the ellipse.
Specifies the width of the rectangle that bounds the ellipse.
Specifies the height of the rectangle that bounds the ellipse.
Width, in pixel, of the pen used to draw the rectangle.
The ellipse color. A suitable color value can be obtained by using the ARGBI() method.
Set to True to apply the Antialiasing algorithm else False.

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.
PenWidth
Width, in pixel, of the pen used to draw the rectangle.
PenColor
The ellipse color. A suitable color value can be obtained by using the ARGBI() method.
AntiAlias
Set to True to apply the Antialiasing algorithm else False.

Return Value

A member of the GdPictureStatus enumeration.
Remarks

This method requires the Image Documents component to run.

Example
Drawing a rotated ellipse on a GdPicture image.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int left = 50, top = 100, width = 250, height = 150;
    float angle = 30.0f;
    int penWidth = 10;
    Color penColor = gdpictureImaging.ARGBI(255, 0, 0, 255);
    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, gdpictureImaging.ARGBI(0, 0, 0, 0));
 
    // Draw 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.DrawRotatedEllipse(imageID, angle, left, top, width, height, penWidth, penColor, true);
 
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
