I'm writing a technical paper and there's a small annoyance on the pdf of my paper. At the bottom of the first page in the footnote the text
ACM ISBN 978-1-4503-2138-9.
DOI: 10.1145/1235
appears. This text throws the formatting of my paper off significantly and it leaves a huge gap of white space towards the bottom of the first page. How can I get rid of this? Is it a problem with the document class "sig-alternate-05-2015"?
Use the etoolbox package and its \patchcmd macro to selectively change sig-alternate' s definition of \maketitle, i.e. remove the \@copyrightspace macro (which is responsible for the copyright space).
\documentclass{sig-alternate}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\maketitle}{\@copyrightspace}{}{}{}
\makeatother
\begin{document}
\author{lockstep}
\title{How to remove the copyright space}
\maketitle
\blinddocument
\end{document}
(The blindtext package is only used to add some dummy text to the example.)
Well, I think I have some sort of a solution now. Basically, since the spacing between rows/lines in Latex is apparently controlled by \baselineskip, one essentially has to ensure that a section heading takes up a vertical space, which is integer multiple of \baselineskip (i.e., it is quantized :)).
That would mean (I guess) is, either letting Latex typeset the section heading, and then trying to figure out the remaining height to add as vertical space, which seemed kind of tedious - or wrapping everything (related to the section heading) in a box with specified height, and letting Latex take care of the rest.
From the approaches I tried, the easiest (see code comments) seems to use a \parbox preceeded by a \noindent (or \parindent = 0pt), with a specified height; in the question, the image shows the section heading (by default) takes a little more than three line heights - so the \parbox here is specified to be 3\baselineskip; the code shows simply the replacement that needs to be done around \section
...
%%% \@startsection {NAME}{LEVEL}{INDENT}{BEFORESKIP}{AFTERSKIP}{STYLE}
% parbox seemingly inserts parindent, even for a section; \noindent fails if inside \parbox; but works if first (and in group!) & matches OK int\baseline
% minipage kills beforeskip/afterskip of section
% vbox seems ok, but then needs to be less than int\baseline skip to match OK
{\noindent%
\parbox[t][3\baselineskip]{\linewidth}{
% \begin{minipage}[t][3\baselineskip]{\linewidth}
% \vbox to 3\baselineskip{
\section{Vivamus}
% }
% \end{minipage}
}%
}
% \lipsum[21-30]
...
... which results with following PDF rendering:
... and correspondingly, since subsequent rows/lines match now - also the bottom rows between the two columns are aligned.
In any case, if there is a different solution, I'd love to hear it ...
Cheers!
