Generating complex type PDF in JAVA using iText

Last days I was searching for generating a PDF in android using iText, I found some of posts but all these posts were containing some sort of basic hello PDF reports and my requirements was to generate a complex type PDF for client reporting purpose.

So I came across the solution and want to share the source code and stuff for audience time saving purpose. Hope this helps some body :).

Note: This source code works on any java platform and not specific to Android only.

The PDF contains almost all components such as drawing tables, images, lines, different types alignments, strike through text, underline texts, different fonts and page division etc. Looks like:
