Fill shape

   <source lang="java">

import java.awt.Color; import java.io.FileOutputStream; import com.lowagie.text.Document; import com.lowagie.text.pdf.PdfContentByte; import com.lowagie.text.pdf.PdfWriter; public class MainClass {

   cb.saveState();
   cb.setColorFill(Color.yellow);

Set shape color

   int total = reader.getNumberOfPages() + 1;
   for (int i = 1; i < total; i++) {
     over = stamper.getOverContent(i);
     over.beginText();
     over.setFontAndSize(bf, 18);
     over.setTextMatrix(30, 30);
