you need to create a .xbb file for each svg file. you can create it
with `ebb -x` command (I am not sure whether it is installed by

fyi, I get this:

extractbb -x flow.svg
extractbb:warning: Can't handle file type for file named flow.svg
ebb -x flow.svg
ebb:warning: Can't handle file type for file named flow.svg
ebb --version
This is extractbb Version 20140317
A bounding box extraction utility from PDF, PNG, and JPEG.

Using TL 2014. May be need to update something.
Thanks for the information below
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.
in this example the image should have width of 1/5 textwidth, original
image size isn't used at all, so the warning shouldn't matter.
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: \g...@base.svg}\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
----------------------------------------
this config file doesn't use image size information from the .xbb
file. as I said, it doesn't work with explicit setting of image size.
(error `Package graphics Error: Division by 0.` is produced)
Here is the command I used
make4ht foo.tex "nma,htm,charset=utf-8" " -cunihtf -utf8"
you can also use
make4ht -uc nma.cfg foo.tex htm
instead
also tried
htlatex foo.tex "nma,htm"
Both give the same warning and the image do not resize.
of course :)
add
\DeclareGraphicsRule{.svg}{svg}{.xbb}{}
to the .cfg file under \DeclareGraphicsExtensions if you want to use
original image dimensions. but if you use that with explicit width
setting, it will fail with `Division by 0` error, as I said earlier.
It is maybe graphicx bug, because the same error is produced with
plain LaTeX.
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.
I forgot it :)
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.
it does use it, but you can modify image generation and conversion in
a build file
