The pstogif script has been rewritten in Perl and it
now accepts more options for specifying color depth, scale factors
and pixel density.
LaTeX figure and other environments are now processed
in 24-bit color.
Figure and table captions are now converted into HTML
rather than becoming part of the inlined image. This means that
any cross-references in the captions will become active.
It is now possible to control for each generated image:
its size
whether it should be inlined or left as an external image
if left as an external image whether it should be accessible
via a generated thumbnail sketch
or a textual hypertext link
These options are available from a new LaTeX command defined in html.sty called htmlimage.
Equations and other inlined images are converted into
transparent GIFs rather than XBMs. This makes it possible
to reduced their storage requirements to about 1/6th of what was
previously required!
The default size of equations and other small inlined
images can be changed
by setting the variable MATH_SCALE_FACTOR in the
configuration files.
The default size of figures, tables, and other large
inlined images can be changed by setting the variable
FIGURE_SCALE_FACTOR in the
configuration files.
Dvips is now called with the -M option which stops it
from invoking METAFONT.
Optimization
Some effort has gone into reducing the amount of memory required
during conversion. The impact of these changes can be very
significant.
In particular, files
containing large numbers of LaTeX commands (eg .aux or .bib)
files are handled much better.
Backwards Incompatible Changes
The option -allbitmaps has been removed. This is no
longer necessary as LaTeX2HTML can now generate transparent
GIF images.
The definition of the command htmladdnormallink in the
file html.sty has changed and the URL will no longer appear
as a footnote in the paper (DVI) version. The translation of
this command into HTML is not affected.
The previous functionality can be obtained with a new command
htmladdnormallinkfoot which will add the URL as a footnote
in the paper version.
The script pstoxbm is no longer distributed as it is not
used.
Bug Fixes
The install-test script now recognizes version
numbers correctly and gives better warnings. It also makes
executable any scripts that need to be so.
Stopped using the nslookup program to try and guess
e-mail addresses (they were used in signing each generated page).
This has been replaced with a simple call
to finger.
Fixed problem which could cause ``Parameter overflow'' in
TeX during image conversion.
The texexpand script has been changed extensively.
Some nasty looping problems are now avoided, and the tracking
down of included files has been improved.
Some reported incompatibilities with some Unix shells
(bash,OSF) have been fixed.
Displayed equations now appear correctly on separate
lines and are right justified.
Fixed bug with nested environments.
Fixed problem which caused the wrong numbers to be assigned
to sections with the same titles when the -show_section_titles
is used (thanks to Brian Toonen <toonen@mcs.anl.gov>).
Fixed problem with the hyperref command which
caused the wrong ``hyperized'' text to appear in the final document.
item optional arguments can now contain one level of
nesting eg item[[First Choice]].
Fixed problems with the ``image caching and reuse'' mechanism
which avoids converting images unnecessarily..
Other Changes
LaTeX2HTML now generates <meta> HTML tags which can be used
by indexing scripts
which generate information for the ALIWEB
search and retrieval tool. The information in the <meta> tags
contains
the title of each separate HTML file.
A new configuration variable DEBUG can be used to preserve
intermediate files for debugging.
Some problems with respect to compatibility with the HTML2.0
standard have been addressed. No more ``unquoted attribute value literals''.
All the navigation icons are now ``lynx friendly''; their
ALT attribute now has a meaningful value.
A new LaTeX command htmlref makes it a lot simpler
to create hypertext links intended only for the HTML version of
the document.
DVIPSK is now recognized by the installation script
Added support for the changebar.sty file by
David B. Johnson (dbj@titan.rice.edu).
It is no longer necessary to add style file names into the
DONT_INCLUDE variable as LaTeX2HTML now does not
attempt to translate file included files ending in .sty.
The small invisible bitmaps that used to mark anchors have been
replaced with the invisible character  .
It is no longer necessary to use full path names when
including external postscript files.
If a file .latex2html-init is found in the ``current
directory'' then this will be loaded automatically after loading the
other default configuration files.
Changed the naming convention of generated HTML files. The
``top'' document is <FILE>.html as before but all other ``nodes''
are named nodeN.html where N is an integer. Also, the file
containing
the footnotes is now called footnode.html.
