% LaTeX2HTML Version 95.1 : html.sty % WARNING: This file requires LaTeX2e. A LaTeX 2.09 version % is also provided, but with restricted functionality. % This file contains definitions of LaTeX commands which are % processed in a special way by the translator. % For example, there are commands for embedding external hypertext links, % for cross-references between documents or for including % raw HTML. % This file includes the comments.sty file v2.0 by Victor Eijkhout % In most cases these commands do nothing when processed by LaTeX. % Modifications: % nd = Nikos Drakos % jz = Jelle van Zeijl % hs = Herb Swan % hs 31-JAN-96 - Added support for document segmentation % hs 10-OCT-95 - Added \htmlrule command % jz 22-APR-94 - Added support for htmlref % nd - Created %%%%MG added \NeedsTeXFormat{LaTeX2e} \ProvidesPackage{html} [1996/02/01 v1.0 hypertext commands for latex2html (nd, hs)] %%%%MG % Exit if the style file is already loaded % (suggested by Lee Shombert \ifx \htmlstyloaded\relax \endinput\else\let\htmlstyloaded\relax\fi %%% LINKS TO EXTERNAL DOCUMENTS % This can be used to provide links to arbitrary documents. % The first argumment should be the text that is going to be % highlighted and the second argument a URL. % The hyperlink will appear as a hyperlink in the HTML % document and as a footnote in the dvi or ps files. \newcommand{\htmladdnormallinkfoot}[2]{#1\footnote{#2}} % This is an alternative definition of the command above which % will ignore the URL in the dvi or ps files. \newcommand{\htmladdnormallink}[2]{#1} % This command takes as argument a URL pointing to an image. % The image will be embedded in the HTML document but will % be ignored in the dvi and ps files. \newcommand{\htmladdimg}[1]{} %%% CROSS-REFERENCES BETWEEN (LOCAL OR REMOTE) DOCUMENTS % This can be used to refer to symbolic labels in other Latex % documents that have already been processed by the translator. % The arguments should be: % #1 : the URL to the directory containing the external document % #2 : the path to the labels.pl file of the external document. % If the external document lives on a remote machine then labels.pl % must be copied on the local machine. %e.g. \externallabels{http://cbl.leeds.ac.uk/nikos/WWW/doc/tex2html/latex2html} % {/usr/cblelca/nikos/tmp/labels.pl} % The arguments are ignored in the dvi and ps files. \newcommand{\externallabels}[2]{} % This complements the \externallabels command above.

The argument of \htmlimage % is really a string of options separated by commas ie % [scale=],[external],[thumbnail= % The scale option allows control over the size of the final image. % The ``external'' option will cause the image not to be inlined % (images are inlined by default). External images will be accessible % via a hypertext link. % The ``thumbnail'' option will cause a small inlined image to be % placed in the caption. The size of the thumbnail depends on the % reduction factor. The use of the ``thumbnail'' option implies % the ``external'' option. % Example: % \htmlimage{scale=1.5,external,thumbnail=0.2} % will cause a small thumbnail image 1/5th of the original size to be % placed in the final document, pointing to an external image 1.5 % times bigger than the original. \newcommand{\htmlimage}[1]{} %%% HTMLADDTONAVIGATION % This command appends its argument to the buttons in the navigation % panel.
