Re: How to write equations for FOP ?

[Vaclav PEROUTKA]

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 John Burgess wrote: 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. http://cvs.apache.org/viewcvs.cgi/xml-fop/examples/mathml/ Pascal -----Message d'origine----- De : Pascal Sancho Envoyé : lundi 13 septembre 2004 14:47 À : [EMAIL PROTECTED] Objet : RE: How to write equations for FOP ? Hi, I think that a good way is to generate svg code embedded in a fo:instream-foreign-object. You can visit http://xml.apache.org/fop/graphics.html#svg-pdf-graphics.

Hello list, I would like to know how can I use FOP with math equations correctly. I currently process equations in LaTeX and insert images but FOP has 72dpi resolution. For PDF documents it is useless. How can I set at least 300dpi resolution or is there any better approach to generate equations in XML ? Thanks, Vasek
