I want to convert an existing A4 PDF document into an A3 PDF using Java. Since I am new to the iText API, I wonder if anyone can guide me how to do this. A sample would be appreciated. Note: the output PDF should be an A3 booklet format.
I have a PDF document which has AcroForm text fields. Now I want to insert a signature image in one of the those fields. I want to place an image on top of the text field position and resize the text field to match the image size.
