[tex4ht] [bug #586] Incompatibility with package animate

[Michal Hoftich]

Jim,

I think that in this case it would be best to convert glideranim.pdf
to an animated format that is supported by web browsers (I think SVG
should allow this, or GIF). I am not really a fan of conditional tests
for TeX4ht in the document text, but if you have only a few
animations, it could be the best option.

Another option would be to redefine the \animategraphics command to
use \includegraphics in the config file. Something like this:

\Preamble{xhtml}
\DeclareGraphicsExtensions{.svg,.gif,.png,.jpg}
\renewcommand\animategraphics[5][]{\includegraphics{#3}}
\begin{document}
\EndPreamble

This will search for glideanim.svg and glideanim.gif and include them
as normal pictures.

Best regards,
Michal

If you are interested then you can see the output at https://joshua.smcvt.edu/computation/book.pdf on page 49.  (I think you may have to use Acrobat to see the animation.)

But I wonder if maybe the right answer is that you shouldn't support this, that a person who has this should separately bundle the graphic files into a .gif or some other format suitable for the web?  Then in the .tex file calls for this could be surrounded with the \ifx\HCode\undefined ... construct.  If that is right, perhaps this could be noted somewhere?
