Dear Max, results of our work (not the latest one, but still good enough for publishing) is available from cvs.sourceforge.net/cvsroot/jeuclid. Now I'm waiting for feedback from anyone of Apache FOP members on review the JEuclid code. At the moment, I have no idea whether some work has been done in this regard.
Present status of our work (we still performing some regression tests, but its 99% already done) is the following: - we have merged JEuclid with FOP 0.20.5 (version available under sf.net is based on one of the pre 0.20.4). - we remove all references to AWT library, so now JEuclid is able to work on "screenless" servers without XWindows configuration. - support "badly" fonts (e.g. Arial Unicode MS, which we are enforced to use for MathML rendering). Due to last two issues we extended metric files with extended information about symbol location within the glyph. Plans for merging into 0.90 and later are not exists so far because we do have to improve the following functionality of the FOP itself to satisfy our needs (these features are done by us for FOP 0.20.5). 1. Support of embedded PDF's using itext library. 2. Support of the specific logging into files without any use of console (from my point of view, this is absolutely dummy requirement and we can use log4j, but I'm not in charge to modify it). 3. Support of Arial Unicode MS as TYPE1 font, and not as TYPE0 font. 4. Support of "phantom" attribute on page-sequence. To hide particular pages in PDF result file but take them into account in page numbering. 5. Support both JDK 1.3 and 1.4. This requires us to integrate support of SAXON parser for JDK 1.4 due to nasty bug in xalan shipped with JDK 1.4. However for JDK 1.3 we still have to keep support of xalan. 6. Improving text layout within the merged table cells for lists (I'guess that for FOP 0.90 it is not the issue anymore). 7. Implement specific DTD lookup algorithm (e.g. search for DTD not only in the XML location but also in current directory). From one hand we would like to have the JEuclid integrated into FOP ASAP, however, we cannot follow release schedule of the FOP due to very major changes of FOP due to features above. As far as I understood Jeremias, he recommended us wait until FOray will be integrated into main branch, but this work still not completed (or even canceled???). Concerning licensing issue. We have contacted the JEuclid original publishers and got their permission to re-publish JEuclid to the AFL license as required for FOP integration. Internally, from our side we got all the permissions to publish our work as well. We can commit all necessary statement as required by ASF once our work will be accepted for publication. Concerning your issues: - I would say this is good idea to include jeuclid into xmlgraphics. However, we need some FOP developers comments on the extended metric file. Otherwise, output will be useless in producing paper-ready PDF's. - We already doing that, however only for the TIFF format. This can be easily done by means of fo:external-graphics in the stylesheet (if I understood your work right). - This feature we are mostly interested in. At the moment this implemented by means of xsl:copy-of due to misinterpretation of character entities in xsl:copy implementation. You are absolutely free to re-use our results in any way under terms of AFL.
