[tex4ht] graphics Images no longer resize in TL 2015 with tex4ht, need help finding why

Wed Jul 22 22:49:03 CEST 2015

Update:

I gave up trying to find why the pure svg method does not resize
with tex4ht anymore. So I rewrote a new detailed instructions
based on using eps files to obtain the bounding box as
suggested by CVR in

http://comments.gmane.org/gmane.comp.tex.tex4ht/1030

This method works well and all images are resized and are
still in SVG in the page, so they look good at different
resolution. (the page below was build using this method)

http://12000.org/my_notes/faq/LATEX/layout/index.htm

I kept the old method instruction on the page for
reference, but it does not work on TL 2015.

Using the eps method only requires one to make an eps file
from each pdf file. This is basically the only extra step needed.
But all of this can be automated using makefiles so it
is not a problem.
