    Example
    Rendering a portion of an image with a circle onto the background image and saving the result into a png file.
    using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    {
        System.Drawing.Drawing2D.InterpolationMode iMode = System.Drawing.Drawing2D.InterpolationMode.Default;
        int backColor = gdpictureImaging.ARGBI(255, 0, 255, 0); // Green color
        int circleColor = gdpictureImaging.ARGBI(255, 255, 0, 0); // Red color
     
        int dstLeft = 0;
        int dstTop = 0;
        int dstWidth = 200;
        int dstHeight = 200;
     
        int srcLeft = 0;
        int srcTop = 0;
        int srcWidth = 40;
        int srcHeight = 40;
     
        // Create background image.
        int backImage = gdpictureImaging.CreateNewGdPictureImage(200, 200, 32, backColor);
     
        // Create image with circle.
        int circleImage = gdpictureImaging.CreateNewGdPictureImage(80, 80, 32, gdpictureImaging.ARGBI(0, 0, 0, 0));
        gdpictureImaging.DrawFilledCircle(circleImage, 40, 40, 80, circleColor, true);
     
        // Draw portion of image with circle into the background image.
        gdpictureImaging.DrawGdPictureImageRect(circleImage, backImage, dstLeft, dstTop, dstWidth, dstHeight, srcLeft, srcTop, srcWidth, srcHeight, iMode);
        gdpictureImaging.SaveAsPNG(backImage, "output.png");
     
        // Release used resources.
        gdpictureImaging.ReleaseGdPictureImage(circleImage);
