acmoverpicpositioningtemplates
I wanted to ask how to position pictures in ACM template in a row covering both columns. For example, when I add pic1, pic2, pic3 and pic4, they go below each other. I need two of them to stay in the same row (1 per column) and other two right below them. I found a tread: How to add two pictures in a single column? How to add four pictures in a single row?
but it doesn't help me.
Can anyone help me
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!

Some changes to the way \maketitle is defined by the class are necessary. Do not modify the original .cls file, though; you can either use the redefinition in your .tex document, as I did in my example code below (notice the section between \makeatletter, \makeatother commands), or make a copy of acmlarge.cls, call it myacmlarge.cls and replace the \maketitle definition in the copy with the definition of my example (without using \makeatletter and \makeatother, in this case); save the copy in your local TDS tree or in your current working directory and then use
\documentclass[prodmode,acmtap]{myacmlarge}
in your document.

\begin{abstract}
It has been previously proposed that understanding the mechanisms of
contour perception can provide a theory for why some flow-rendering
methods allow for better judgments of advection pathways than others.
In the present article, we develop this theory through a numerical
model of the primary visual cortex of the brain (Visual Area 1) where
contour enhancement is understood to occur according to most
neurological theories. We apply a two-stage model of contour
perception to various visual representations of flow fields evaluated
using the advection task of Laidlaw et al. [2001]. In the first
stage, contour {enhancement} is modeled based on Li's cortical model
[Li 1998]. In the second stage, a model of streamline {tracing} is
proposed, designed to support the advection task. We examine the
predictive power of the model by comparing its performance to that of
human subjects on the advection task with four different
visualizations. The results show the same overall pattern for humans
and the model. In both cases, the best performance was obtained with
an aligned streamline-based method, which tied with a LIC-based
method. Using a regular or jittered grid of arrows produced worse
results. The model yields insights into the relative strengths of
different flow visualization methods for the task of visualizing
advection pathways.
