Changes upto v96

Tables and math support for HTML 3.0

Tables can now be specified in HTML, without having to generate a GIF image. Code is also available for HTML 3.0 equations, but it is not currently turned on, since no browser can handle it (yet!) (Courtesy of Marcus Hennecke <marcush@crc.ricoh.com>)

Font generation at screen resolutions

The quality of equation bitmaps is greatly improved by enabling the $PK_GENERATION configuration variable. When this is done METAFont will be invoked through dvips to generate fonts more suitable to screen viewing. Ideally, this should be done by setting the mode switch to dvips, but unfortunately not all version of dvips support this option. For those that don't, a .dvipsrc file is supplied with this distribution. Sidik Isani (<isani@cfht.hawaii.edu>) provided this change.

Improved support for active image maps

Both server and client-side maps are supported. Image maps can either be inline or external. External maps can be associated with a thumbnail image. A separate script makemap helps resolve external URLs in image maps. (Herb Swan <dprhws@edp.Arco.com>)

Improved image sharing and recycling

The older version of image recycling often caused images to overwrite each other due to confusion in the bookkeeping. This has been fixed. It is also no longer necessary to keep generating the same image which is being used repeatedly in a document. Furthermore, images with thumbnails can now be recycled, as well as active image maps. Only images of the correct size are recycled. (Herb Swan)

Document segmentation

Large documents can now be divided into independently processed segments. Additional command line switches provide intersegment navigation information, while automatically generated Perl files pass symbolic references and counter information between segments. (Herb Swan, assisted by Michel Goossens <Michel.Goossens@cern.ch>)

Command parsing made more like LaTeX's

Constructs like \hello2 are now treated as macro hello followed by argument `2', rather than as macro hello2. Added and commands. (Marcus Hennecke)

Graceful termination upon interrupt

When LaTeX2HTML is interrupted by a termination signal, all child tasks are also terminated. This provides a more orderly shutdown than that offered by previous versions. (Herb Swan)

Support for textual font size changes

HTML 2.1 support is now available fo ISO 10646 Unicode character sets by specifying -html_version 2.1. HTML 3.0 support is provided for textual font size changes (like <SMALL>), used in conjunction wich a generated optional style sheet. (Marcus Hennecke)

More inline math generated in HTML

Small inline equations which can be typeset in HTML are typeset in HTML. This further reduces the nuber of GIF files that need to be generated.

Hypertext references can now be external

The commands htmlref and hyperref now accept labels defined in an external document if the internal reference is not found. (Herb Swan)

Additional style files are now available

These were provided by Herb Swan:

htmllist

Defines a fancier list environment, such as this. (It is the same as the description environment in the paper version.)

heqn

Redefines the equation environment so that equation numbers are handled in HTML. This causes equations in this environment to be recyclable. It also causes equation arrays to be recyclable if their equation numbers do not change from the previous run.

floatfig

Provides support for this environment by making it look like an ordinary figure in the electronic version.

wrapfig

(Same comment as for floatfig).

graphics

Defines elements of the standard LaTeX2e graphics package.

More support for LaTeX2e

Provided support for the ensuremath command. The last option to the babel package is interpreted as the LaTeX2HTML language style file to load. User-defined commands and environments can now have an optional argument. Stubs have been provided for enlargethispage and suppressfloats. LaTeX2epackages alltt, graphics, graphicx, color and epsfig were provided. This manual itself was transformed into standard LaTeX2e. (Herb Swan and Michel Goossens)

Orientation manipulation for figures

The flip= option of htmlimage causes the program pnmflip to be called prior to the generation of the GIF file. This allows the electronic version of the image to be oriented differently than the paper version. (Herb Swan)

Better treatment of null images

If for some reason an image produced a null GIF file, then no reference is made to that file and the program proceeds gracefully. Furthermore, such null images do not need to be regenerated. This would occur in HTML 3.0 images whose caption is enclosed in a parbox, for example. (Marcus Hennecke)

Independent control over top/bottom navigation panels

There are now separate subroutines to control the top and bottom navigation panels. (Jens Krinke <krinke@ips.cs.tu-bs.de>).

Labels, equations and images in section headings

All of these items are now permitted inside a section heading, and in the \title{} command. However, the equations may not look very good because of the size difference. (Herb Swan)

Other changes

The following other numerous changes are in no particular order:

• Fixed the treatment of @{} expressions in HTML 3.0 tables.
• Made the reuse command line switch accept an option.
• Made the .tex filename suffix optional. (This will save a bit of typing!)
• Added a -debug command line switch.
• Support unbreakable spaces (~) and itallic correction.
• Fixed a bug in pstogif which caused ppmquant never to be called.
• The \special   command can now be used outside of a figure environment. This is useful for specifying a PostScript prolog to dvips.
• Added the configuration variable $TEXINPUTS to point to the path of LaTeX style files that LaTeX2HTML should interpret.
• Added the configuration variable $DVIPS_MODE to specify:
  1. That dvips understands the -mode switch, and
  2. Which METAFont mode to use for dynamic font generation.
  3. The default output file prefix.
• Fixed up comment removal code to remove all comments during preprocessing.
• Make $LATEX2HTMLSTYLES a path list (and support `~' as a way of specifying the home directory).
• Replace double dashes with a single dash.
• Removed extraneous spaces in comma separated citations.
• Changed encoded `~' character to a real `~' character at end of conversion
• Eliminated the spurious newline that was appended to macro expansions.
• Improved the error reporting of install-test.
• Remove whitespace from beginning of unnumbered section names.
• Add other language support for TOC, figures, tables, and \today.
• Ignore "| and "- strings in german documents.
• Make \hrule insert less vertical whitespace.
• Added an \htmlrule   command to draw a horizontal rule, even within a figure caption.
• The texexpand program now ignores anything after the

  \end{document}

  command, except when it is shielded by the verbatim environment.
• The optional caption argument is now the one which goes to the list of figures/tables, not the required argument.
• Added a \LaTeXe command.
• Fixed bug in the treatment of the \circ math symbol.
• A comment that appears on the first line of an included file is now properly removed.
• Added a call to replace_user_references, to allow style files to add new types of crossreferences.
• Removed the expansion of `\\' to `\\ ' in verbatim.
• Figure numbers now appear in captions enclosed in parboxes.
• All deferred warning messages are now correctly reported.
• The ``scale='' option of \htmlimage now works.
