GdPicture image identifier.
Specifies the x-coordinate of the center of the circle.
Specifies the y-coordinate of the center of the circle.
Diameter of the circle in pixel.
Color of the circle. A suitable color value can be obtained by using the ARGB() method.

Parameters

ImageID
GdPicture image identifier.
DstLeft
Specifies the x-coordinate of the center of the circle.
DstTop
Specifies the y-coordinate of the center of the circle.
Diameter
Diameter of the circle in pixel.
FillColor
Color of the circle. 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.
Example
Drawing a filled circle.
Rendering an image with a circle onto the background image and saving the result into a png file.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

    Color backColor = gdpictureImaging.ARGB(255, 0, 255, 0); // Green color

    Color circleColor = gdpictureImaging.ARGB(255, 255, 0, 0); // Red color

 

    // Create a background image.

    int backImage = gdpictureImaging.CreateNewGdPictureImage(320, 200, 32, backColor);

 

    // Create an image used for drawing, and draw a circle on it.

    int circleImage = gdpictureImaging.CreateNewGdPictureImage(80, 80, 32, gdpictureImaging.ARGB(0, 0, 0, 0));

    gdpictureImaging.DrawFilledCircle(circleImage, 40, 40, 60, circleColor, false);

 

    // Draw an image with a circle onto the background image.

    gdpictureImaging.DrawGdPictureImage(circleImage, backImage, 0, 0, 80, 80, System.Drawing.Drawing2D.InterpolationMode.Default);

    gdpictureImaging.SaveAsPNG(backImage, "output.png");

 

    // Release used resources.

    gdpictureImaging.ReleaseGdPictureImage(circleImage);

    gdpictureImaging.ReleaseGdPictureImage(backImage);

}
Filling a green circle with a center at 200, 250 and a diameter of 100 pixels.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())

{

    int centerX = 200, centerY = 250, diameter = 100;

    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, Color.White);

 

    // Fill the circle. The AntiAlias parameter is set to true to apply antialiasing algorithm, i.e. to improve the appearance of the circle boundary.

    gdpictureImaging.DrawFilledCircle(imageID, centerX, centerY, diameter, Color.Green, true);

 

    gdpictureImaging.SaveAsPNG(imageID, "output.png");

 

    // Release used resources.

    gdpictureImaging.ReleaseGdPictureImage(imageID);

}
Example
