Thanks, (I guess Dr.) Shigeharu Takeno! Gratefully once again you have
solved a problem for me! Your solution of the LaTeX command \int\limits
_{-\infty\hspace{2mm}}^{+\infty} between \begin{equation} and \end{equation}
in a .tex file worked well to eliminate the black line segment under my test
integral sign with its limits in the .html file produced with a latex2html
command on that .tex file! And gratefully I was able to extend your
principle by using \hspace{8mm} within a lower limit and to the right of the
lower limit's contents to also eliminate a black line segment under another
integral sign with fractions in the upper and lower limits.
Dr. Takeno, I could begin to realize at least part of what you wrote by
looking at the .png (Portable Network Graphics) image equivalent to
\int\limits _{-\infy}^{+\infty} by looking at the .png (Portable Network
Graphics) image in the Gnu Not Unix (GNU) Image Manipulation Program (GIMP)
2.6.8 in my Linux operating system. What program do you use to examine .png
images in detail and in what computer operating system? In GIMP I could see
that the right-hand portion of the upper limit of positive infinity was
either right at the right-hand edge of the dash-lined box surrounding the
image or perhaps was cut off there; I'm not sure. Can you or someone
explain to me the mechanisms in detail that cause the unwanted black line
segments to be generated? So far I know from you, Dr. Takeno, that if a
mathematical expression inside an image would otherwise extend beyond the
right border of the image, somehow the black line segment was generated
underneath the image. You explained something about the first step of the
cropping procedure which was involved.
I just guess from what you wrote, Dr. Takeno, that the script eqnfix.sh
obtained from http://www.vyvy.org/main/en/node/102 on the Internet might
not have been able to eliminate the black line segment under my integral
sign due to a piece of the upper limit that otherwise would have extended
beyond the right border of the .png image.
However, there is a mystery of how Nasser M. Abbasi's combination of
installed software could avoid producing the black line segment under the
integral sign. Based on what Dr. Takeno wrote my guess is that in Nasser M.
Abbasi's case the width of the rectangle containing the integral sign and
its limits might have been wide enough to keep the limit of positive
infinity from reaching the right-hand border of its enclosing rectangle. I
saw that Nasser Abbasi and I have been recently been using the same,
LaTeX2HTML Version 2008 (1.71) and the same version of dvips(k) 5.98. His
version of Perl has been 5.10.1; mine is 5.12.1. His installed version of
Ghostscript is 8.71; mine is 8.70. But I have been wondering if our
versions of Netpbm could have been different and have been responsible for
our different results; in particular the version of pnmcrop and the
parameters used with it could be very important in the outcome regarding
removing the unwanted black line segment. My version of Netpbm has been
10.35.74. There may be other ways, Nasser, in which you may learn what your
version of Netpbm and/or pnmcrop is/are in your Ubuntu Linux operating
system. For example, try typing the command "pnmcrop -v" or
"pnmcrop -version." In my case I found the version of Netpbm installed on
my computer listed near the top of the file
/usr/share/doc/packages/netpbm/HISTORY. Another way I found it was by
entering Yet another Software Tool 2 (YaST2) and within "Software
Management" searching for "netpbm," selecting "netpbm" among the results
found, and then clicking on the "Technical Data" tab to finally read under
"Installed Version" 10.35.74-2.21. If your Ubuntu, Linux operating system
instead uses the Yellow-dog Update Manager (YUM), try using it somehow,
perhaps in a search for "netpbm" to determine the version of Netpbm you have
installed on your computer.
Thanks, Professor Ross Moore, for suggesting I use the -debug option in a
latex2html command. That's how I could obtain the output below, I think for
a case in which the unwanted black segment was generated:

Not using the -no_math option in a latex2html command by itself in my case
did not eliminate the unwanted black line segment. I also tried using
the -noreuse option in a latex2html command. But that involved choosing the
"d" or "D" option, which deleted the images previously produced and made new
ones. Fortunately that was not necessary for me to regularly do with a
large .tex document; instead new .png images were made, replacing old .png
images without using the -noreuse option in a latex2html command. And that
saved time not having to remake many other .png images with which there were
no major problems. Sometimes, however, I did "Move to Trash" a whole folder
of .png images to make new ones. Thanks to all of you who have kindly taken
time to post your ideas and data for me here!

I confirm the problem for the following LaTeX source:
\documentclass[12pt]{article}
\begin{document}
\[
\int\limits _{-\infty}^{+\infty}
\]
\end{document}
and using "-html_version 3.2,math".
This may be the reason why the top infinity mark is too long to
the right. In fact, the right end of the mark is over the black
under bar. Then, the small space remains to the right of the
black under bar at first cropping, and the black line will not
remove the following croppings.
To workaround, to make a long black under bar:
\documentclass[12pt]{article}
\begin{document}
\[
\int\limits _{-\infty\hspace{2mm}}^{+\infty}
\]
\end{document}
