Thanks all, I will try it.

I attach the jar which you need to put on your class path or otherwise =

Then what follows is some simplified extracts from my xslt.

Re: How to write equations for FOP ?
John,
it would be nice to have it. Then I could use width and height in
percent to recompute the scale don't I ?
Anyway I am not sure if I am able to integrate it into FOP because I
started with XML and XSLT week ago what my colleagues did not finish...
Thanks,
Vasek

By default fop assumes bitmaps are 72dpi so it will spread a 144x144 pixel
bitmap across 2 inches in width and height.
However, if you tell it the size you want
ie width="1cm" height="1cm"
then it will produce the bitmap at that size.
If your bitmaps are all of different sizes then I have written a java class
for use as an xslt extension that reads the bitmap and reports back the
width and height in pixels. I can submit the source code and the jar if
there's interest - I've only tested it with jpegs but it should work with
any bitmap type supported by the javax.imageio package. I believe there is
a plug in that will do GIFs though it's not part of the standard
distribution because of the lzw patent problem.

Hi Pascal,
thanks for an answer but I am not sure if it solves my problem. It still
generates GIF images with resolution of 72dpi. And for this resolution I
see pixels - formulas are very rough. For SVG it looks it is only the
bitmap wrapper, isn't it ?

You can check it out (from the maintenance branch), build FOP and create
a servicec entry for the MathML element mapping (there should be a sample),
it should work then.
The MathML extension is in CVS HEAD under examples/mathml, not in the
maintenance branch. And it will probably take a bit to adjust it for FOP
0.20.5.

Hi,
I think that a good way is to generate svg code embedded in a
fo:instream-foreign-object.
You can visit

I'll get in touch with him. I've no problems licensing wise, but I'd like to do things like add a few comments etc before too many people see it. I'm surprised it doesn't exist already - I couldn't find anything when I searched before writing this, but had a horrible feeling all the time that I must be re-inventing the wheel. - Original Message - From: Clay Leeds [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, September 13, 2004 4:45 PM Subject: Re: How to write equations for FOP ?
