I have a 1 inch top margin in all the pages that I have in my DVI file. When I convert this to PDF however the top margin reduces! I am not sure why this is happening. Could someone tell me how to ensure a top margin of at least 1 inch in the PDF?
As Alexander Grahn suggested - instead of using
dvipdf you could do it in two steps:
dvipswith the desired paper option, such as
dvips -t a4 file.dvi
ps2pdfwith the desired paper option, it takes the same as
gsaka ghostscript, such as
ps2pdf -sPAPERSIZE=a4 file.ps
I recommend using pdfLaTeX for directly producing PDF without those conversions, it has further benefits for example its microtypographic capabilities.
