<DD>Looks like the configuration command was inserted somewhere between <code><SPAN CLASS="cmtt-10">\usepackage[...]{tex4ht}</SPAN></code> and
<code><SPAN CLASS="cmtt-10">\begin{document}</SPAN></code>, in the root source file. Try inserting it after the <code><SPAN CLASS="cmtt-10">\begin{document}</SPAN></code> or, a much nicer approach,
into a separate configuration file.

<DD>Use the <SPAN CLASS="cmtt-10">\Contribute{TITLE}{...} </SPAN>command to redefine for the these elements the harmful macros
that appear in headers of logical units like <code><SPAN CLASS="cmtt-10">\title</SPAN></code> and <code><SPAN CLASS="cmtt-10">\chapter</SPAN></code>. For instance, the definition
<code><SPAN CLASS="cmtt-10">\Contribute{TITLE}{\def\LaTeX{LaTeX}}</SPAN></code> for the source <code><SPAN CLASS="cmtt-10">\title{with \LaTeX}</SPAN></code>.

<!--4508--><p class="indent"> <DT>Truncated and empty gifs for Xfig pictures
<DD>Some Xfig files are made up of overlapping picture environments, with TeX4ht viewing the components as
defining independent figures. The problem can be solved by importing the Xfig files into pictorial environments of
TeX4ht.

<!--4534--><p class="indent"> in tex4ht.env. The quality of the gif's can be improved by replacing `<code><SPAN CLASS="cmtt-10">-mode ibmvga -D 110</SPAN></code>' with another mode
having a better resolution. The Metafont file modes.mf, and maybe also a local.mf file, list possible modes (note,
however, that your platform might not have all of these modes installed). If you'll just remove the
switches `<code><SPAN CLASS="cmtt-10">-mode ibmvga -D 110</SPAN></code>' from the dvips, you'll also likely to get better results due to a higher
resolution of the default setting. The dimensions of the gifs can be changed with the parameter `<code><SPAN CLASS="cmtt-10">-density</SPAN>
<SPAN CLASS="cmtt-10">110x110</SPAN></code>'.
