Hello all, first time here.
I'm currently using LyX to write a medium size build manual for model aircraft,
this includes numerous JPEG images
which are currently included using \includegraphics{}.
Everything works 'delightfully' when I go from LyX->PDF, so this email isn't
about that.
Where my problems come is when I go LyX -> LaTeX and then pipe that through to
L2H. The images are progressive PNG's
with a limited colour selection, clearly PNG isn't suited for my situation
where I'm using JPEG images.
PNG's don't have a particularly limited color selection, as far as i know;
they're capable of producing just as good (or better) images as jpeg,
but probably not quite as compressed (jpeg uses lossy compression).
Anyway, jpeg is also a reasonable image format for web (as well as pdf), why
not use it?
You say you are using JPEG images, but the html below suggests you're using eps
(presumably wrapped/converted from the source jpeg ?). This is most likely the
source of the problem: latex2html doesn't know there's a jpeg embedded, so it
has
to "print" the picture, and extract a bitmapped copy of it (like it does for
math),
but in this case, the resolution will mismatch and give bad results.
I don't use LyX, so I don't know if it gets in the way of the following
approach:
If you have an original image in jpeg format, say picture1.jpeg. Then, use
whatever program you like (gimp, ImageMagick,...) to produce a postscript
version
and call it picture1.eps. Now in the latex source use
\includegraphics[whatever]{picture1}
_without_ the extension. The includegraphics package is clever and will find
the
most appropriate format for the current processsing: LaTeX will use the eps,
pdflatex and latex2html would use the jpeg. Then you should get pretty good
results in all cases.
What I thought I might be able to do is to get l2h to reference the image files
as a link, since I can upload all the
required images with the html files ... I tried the following
latex2html -html_version 4.0 -split 2 -local_icons -show_section_numbers
-external_images -ps_images qf2bm-001.tex
This generates output like ...
<IMG
WIDTH="170" HEIGHT="128" ALIGN="BOTTOM" BORDER="0"
SRC="img130.png"
ALT="\includegraphics[%
width=100dd]{manual-photos/07pic00044.jpg.eps}">
Where's I'd rather something like
SRC="manual-photos/07pic00044.jpg.eps">
from which I could just clean up with sed or other such.
Other than the images, L2H is fantastic, great work.
