Adding an image to a PDF using iTextSharp and scale it properly

Question

I solved it using the following:

foreach (var image in images)
{
    iTextSharp.text.Image pic = iTextSharp.text.Image.GetInstance(image, System.Drawing.Imaging.ImageFormat.Jpeg);

    if (pic.Height > pic.Width)
    {
        //Maximum height is 800 pixels.
        float percentage = 0.0f;
        percentage = 700 / pic.Height;
        pic.ScalePercent(percentage * 100);
    }
    else
    {
        //Maximum width is 600 pixels.
        float percentage = 0.0f;
        percentage = 540 / pic.Width;
        pic.ScalePercent(percentage * 100);
    }

    pic.Border = iTextSharp.text.Rectangle.BOX;
    pic.BorderColor = iTextSharp.text.BaseColor.BLACK;
    pic.BorderWidth = 3f;
    document.Add(pic);
    document.NewPage();
}

Personally, I use something close from fubo's solution and it works well:

image.ScaleToFit(document.PageSize);
image.SetAbsolutePosition(0,0);

You can try something like this:

      Image logo = Image.GetInstance("pathToTheImage")
      logo.ScaleAbsolute(500, 300)

image.ScaleToFit(500f,30f);

this method keeps the aspect ratio of the image

image.SetAbsolutePosition(1,1);
