General ⇒ Special margins on certain pages

[emf2268]

I have a document I'm trying to write in Latex. It is generated by a PHP script; the first page may or may not have enough text to move to the next page. Now, the second page forward has a header, and thus a non-zero header height, separation, and top margin. The first page, however, does not have a header and the text is near the top of the page. How can I tell Latex to change the margins once the first page is over?

I tried \afterpage{\headsep 10pt} (or whatever the size is) and other examples of \afterpage, but it does not seem to execute. I can't do a hard page break; I don't know how much content will be on the page since it's generated automatically. Here it my code so far:

Code: Select all

\documentclass[11pt]{article}

\usepackage{afterpage}
\usepackage[strict]{changepage}
\usepackage{ifthen}
\usepackage{endfloat}
\usepackage{lastpage}
\usepackage{amsmath}
\usepackage[left=2cm,top=0cm,right=2cm,bottom=3cm,nohead,nofoot]{geometry}

\usepackage{fancyhdr}
\headheight 0pt
\fancyheadoffset[R]{0in}
\fancyhead[R]{Header}
\renewcommand{\headrulewidth}{0pt}
\pagestyle{fancy}

\begin{document}
\afterpage{\setlength{\headheight}{53pt}}
\thispagestyle{plain}
Text!  Insert a lot of lines here to see the effect I'm talking about.

\newpage
\pagebreak[4]
Text!
\newpage
\pagebreak[4]
More text!

\end{document}

The following code may help you:

Code: Select all

\documentclass[11pt]{article}
\usepackage{lipsum}
\usepackage{afterpage}
\usepackage[left=2cm,top=3cm,right=2cm,bottom=3cm]{geometry}

\usepackage{fancyhdr}
\fancyhead[R]{Header}
\pagestyle{fancy}

\begin{document}

\thispagestyle{plain}
\vspace*{-3cm}
\afterpage{\vspace*{-3cm}\thispagestyle{plain}}
\lipsum[1-30]

\end{document}

I don't understand which should be the layout of the second page. Has it always a header? Has it a header only if the text in the first page is short? If the answer to the first question is affirmative, you should remove the \afterpage command from the above code.

[emf2268]

Every page after the first has a header. It goes like this:

First page:
-No header
-Small top margin

Every other page, even if text from the first page "floats" to the second:
-Header
-Normal top margin

Here's my code now:

Code: Select all

\documentclass[11pt]{article}

\usepackage{afterpage}
\usepackage{ifthen}
\usepackage{endfloat}
\usepackage{lastpage}
\usepackage{amsmath}
\usepackage[left=2cm,top=1cm,right=2cm,bottom=3cm,nohead,nofoot]{geometry}

\usepackage{fancyhdr}
\headheight 0pt
\fancyheadoffset[R]{0in}
\fancyhead[R]{Header}
\renewcommand{\headrulewidth}{0pt}
\pagestyle{fancy}

\begin{document}
\vspace*{-1cm}
\afterpage{\vspace*{2cm}}
\thispagestyle{plain}
Title!

\newpage
\pagebreak[4]
Text!
\newpage
\pagebreak[4]
More text!

\end{document}

But as before, afterpage doesn't seem to have any effect.

No, wait, nevermind. Got it. It works fine. Thanks for your help!
