Hello Ross;
Using latex2html 2008.
I just found a nasty problem. I am trying to convert a large latex file
to html using latex2html.
I have lots of images in different folders. in my latex file I have
things like
\includegraphics[]{A/e4.png}
\includegraphics[]{B/e4.png}
But because the image file itself is called the same (e4.png in this
example), even though there are different and in different folders, one
image will end up overwriting the other during the conversion. I guess
because l2h puts all the images during conversion in one folder (the tmp
folder). So in the final html file, only one image is shown and
duplicated.
No. This cannot be the reason, as LaTeX2HTML does no such copying.
Presumably those \includegraphics commands occur within some kind
of environment, such as a {figure} or {minipage} .
The image is then made of the whole environment, not just
of the included graphic (unless you take LaTeX2HTML-specific
steps to alter this behaviour).
Please show some examples from your source code,
showing exactly how these included images occur,
within (sub-)sections and environments.
I'll try to make a small example to show the problem, but I need time since
this is a large tree and large tex file. But all the graphics including code
looks like this:
\begin{center}
\includegraphics[]
{e1/matlab/e1.png}
\end{center}
....
\begin{center}
\includegraphics[]
{e1/maple/e1.png}
\end{center}
I actually spent the last 6 or so hrs changing all the file names and the
tex file making the names of the images unique. So the problem now do not
exist. But I can reproduce it again.
Of most interest is the graphics.pl file.
This contains the HTML code used to include each image in
the final HTML pages. Each bit is associated to a database 'key'
which is constructed from the LaTeX source coding for the
image --- usually the whole environment.
It is this key that needs to be unique to get different images.
Ok. Thanks for this info.
So, this means, I have now to go and changes all image files names in
all the folders I have and make each unique file name!
Although this would be a solution, it should not actually be necessary.
I have 100's of such images and have to edit the latex file and make the
corresponding changes as well.
How is your LaTeX source structured?
Do you have different chapters or sections in different files
(e.g., using the \include command), or have you thrown everything
in together?
It starts like this
\documentclass[12pt]{article}%
\usepackage{html}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{graphicx}
Then just lots of
\section{bla bla}
\section{bla bla}
\section{bla bla}
etc...
and inside each section is where I include the images, with same name, but
from different folders.
Are the different graphics directories specific to different
sections? If so, then using LaTeX2HTML's "segmented document"
features would most certainly have avoided this problem.
Yes. inside EACH section, I do
\begin{center}
\includegraphics[]
{e1/matlab/e1.png}
\end{center}
....
\begin{center}
\includegraphics[]
{e1/maple/e1.png}
\end{center}
Where in the above, "e1" corresponds to section "1". And I have folders
called "e1" , "e2" , etc....
So within a section, the image names will be the same, but in different
folders.
Is there a trick to make l2h handle such case? I am trying to avoid
having to do the renaming and editing if possible.
There are several possibilities.
But first we need to know exactly what is going wrong.
You have not provided enough information about your
coding to deduce the exact context in which something
is failing.
My command is
latex2html -split 4 -show_section_numbers -subdir -local_icons mim.tex
The -subdir should be redundant, as this is the usual default.
Whenever you have difficulties in the translation, then you
can get more information using -debug <num> (e.g. -debug 1 ).
The higher is <num> then the more extra information is written
to the log output.
In particular, the temporary files are not deleted, so you can
have a look at much of the intermediate information.
With graphics, also use the -reuse 0 switch.
This will force all the images to be remade, as well as
having -debug retain the intermediate files.
thank you,

Hope this helps,
Ross

Thanks, I will try to repoduce it again.
