Phrase p = new Phrase("");
logo.RotationDegrees = 180f;
p.Add(new Chunk(logo, 30, 30, false));
ColumnText.ShowTextAligned(stamper.GetOverContent(i), Element.ALIGN_RIGHT, p, 400f, 5f, 0);

but it shows image left alinged..how to make it right alined?

Answer 1

You are confusing left and right, and left-aligned and right-aligned.

I have an image of a dog and an image of a fox.

I am addding the dog left-aligned, and the fox right-aligned:

Image d = Image.getInstance(DOG);
d.setScaleToFitHeight(false);
Image f = Image.getInstance(FOX);
f.setScaleToFitHeight(false);
Chunk dog = new Chunk(d, 0, 0, false);
Chunk fox = new Chunk(f, 0, 0, false);
PdfContentByte canvas = writer.getDirectContent();
ColumnText.showTextAligned(canvas, Element.ALIGN_LEFT, new Phrase(dog), 250, 750f, 0);
ColumnText.showTextAligned(canvas, Element.ALIGN_RIGHT, new Phrase(fox), 250, 750f, 0);

This is the result:

The dog is to the right, because "left-aligned" means that x = 250 will coincide with the left side of the image will be to the left. The fox is to the left because "right-aligned" means that x = 250 will coincide with the right side of the image.

Answer 2

            FileStream fs = new FileStream(@"D:\test.pdf", FileMode.Create, FileAccess.Write, FileShare.None);
            Document doc = new Document();
            PdfWriter writer = PdfWriter.GetInstance(doc, fs);
            doc.Open();
            iTextSharp.text.Image logo = iTextSharp.text.Image.GetInstance(@"D:\testLogo.png");
            logo.Alignment = 6;
            doc.Add(logo);
            doc.Add(new Paragraph(@"Test"));
            doc.Close();

you just need to set Alignment for your image as 6 form Right Alignment
