Explanation
- Point number 1, just forget every thing its very simple
program, i will show you the road map
- First open OutputStream and give our output PDF file name [ line number 26 ]
- Create Document class object [ line number 27 ]
- Call getInstance() static method from PdfWriter class
- In getInstance() we have 2 parameters, 1 is document object and 2nd one is our OutputStream object
- Now jump to line number 70, we are calling open() method from Document object, means think PDF is opened now
- Come to line number 30, here am going to write some code to insert an image into the PDF document
- Create Image class object and loaded the image and adjusted the dimensions
- Come to line number 72,
add your image object here
- line number 85 we have created new PDF page
- Similarly allllllllllllllll
