Hi Nasser,
I think your setup is too complicated.
First of all, you should conditionals for tex4ht in text of your
document, you should use that only for conditional package loading in
the preamble. You can configure graphicx package to include pdf image
when you compile to pdf and svg when you compile with tex4ht. You only
need to remove the image extension from the document:
\documentclass[12pt]{article}
\usepackage{graphicx}
\begin{document}
% \includegraphics[]{p}
\includegraphics[width=0.5\paperwidth]{p}
\end{document}
Now you need to decide. If you always use
\includegraphics[width=something]{imagename}, you can just configure
graphicx to include svg files and configure tex4ht to support it:
\Preamble{ext=htm,p-width,pic-align} %work well with something, I forgot what
\DeclareGraphicsExtensions{.svg,.png,.jpg}
\Configure{Picture}{.svg}
\makeatletter
\Configure{graphics*}
{svg}
{
{\Configure{Needs}{File: \[email protected]}\Needs{}}
\Picture[\csname a:GraphicsAlt\endcsname]{\csname
Gin@base\endcsname.svg width="\expandafter\the\csname
Gin@req@width\endcsname" height="\expandafter\the\csname
Gin@req@height\endcsname"
}
}
\begin{document}
\EndPreamble
see \DeclareGraphicsExtensions and \Configure{graphics*}{svg}
Thanks Michal. I tried the above option you have, but I have not
been able to get it working. I am on TL 2014. I keep getting
----------------------
(/usr/local/texlive/2014/texmf-dist/tex/generic/tex4ht/html4-math.4ht))
(./foo.aux))
l.6 --- TeX4ht warning --- Cannot determine size of graphic in 2.svg (no Boundi
ngBox) ---
--------------------------------
I tried the build using your make4ht and also using htlatex.
May be I am doing something wrong, but I do not see it.
I have put the folder with the .tex, .cfg and the .svg image
in a zip file if you like to try your self.
http://12000.org/tmp/svg_support/
Here is the tex file:
-------------------------------
\documentclass[12pt]{article}
\usepackage{graphicx}
\begin{document}
\includegraphics[width=0.2\paperwidth]{2}
\end{document}
--------------------------------
There is a file called 2.pdf and 2.svg in the folder.
pdflatex works fine and the image shows small as expected. But
the HTML shows the image as SVG, but not resized due to the
above warning.
Here is the .cfg I am using (from your last email)
------------------------------------
\Preamble{ext=htm,p-width,pic-align} %work well with something, I forgot what
\DeclareGraphicsExtensions{.svg,.png,.jpg}
\Configure{Picture}{.svg}
\makeatletter
\Configure{graphics*}
{svg}
{
{\Configure{Needs}{File: \[email protected]}\Needs{}}
\Picture[\csname a:GraphicsAlt\endcsname]{\csname
Gin@base\endcsname.svg width="\expandafter\the\csname
Gin@req@width\endcsname" height="\expandafter\the\csname
Gin@req@height\endcsname"
}
}
\begin{document}
\EndPreamble
----------------------------------------
Here is the command I used
make4ht foo.tex "nma,htm,charset=utf-8" " -cunihtf -utf8"
also tried
htlatex foo.tex "nma,htm"
Both give the same warning and the image do not resize.
btw, when one writes \makeatletter does one need to also add \makeatother
at the end? I noticed you did not have \makeatother in the above.
Also, since I got your attention, I am confused about one thing:
When using your build system make4ht, does it still use/read the
tex4ht.env or does it not need it? Please let me know if I can
try anything. I'd like to use your method above, since it saves
me having to make .eps for each image.
if you want to include images using their natural size, you need to
extract the boinding box using `ebb -x imagename.pdf` command. This
will create file imagename.xbb. Graphicx package with dvipdfmx option
can then use this file for extracting the bounding box of the image:
\DeclareGraphicsExtensions{.svg,.png,.jpg}
\documentclass[12pt]{article}
\ifdefined\HCode
\usepackage[dvipdfmx]{graphicx}
\else
\usepackage{graphicx}
\fi
\begin{document}
\includegraphics[]{p}
% \includegraphics[width=0.5\paperwidth]{p}
\end{document}
and add to the .cfg file under \makeatletter:
\@namedef{Gin@[email protected]}#1{{svg}{.xbb}{#1}}
\@namedef{Gin@[email protected]}#1{{svg}{.xbb}{#1}}

Michal
