Re: fop-ttfreader - output bounding box information for characters?
Hi Alexey, On 04/01/2013 19:41, Alexey Neyman wrote: snip/ Interesting workaround. We are trying to tackle this issue by providing an alternative implementation of GVTFont in Batik that uses FOP's Font Library to load the font metrics. First, as I was told on the list previously, it is not a small feat and it would take some time before this fix is released. Yes, that is correct. Then, even though it would solve the issue for SVGs, it won't help with font selection for MathML. As I explained below, JEuclid pre-renders the glyphs into paths. That's true. I missed the fact you were working with JEuclid And as far as I can tell, JEuclid project is all but dead: the last non- trivial commit was 16 months ago, and the last release 30 months ago. I don't think it is likely JEuclid will catch up with FOP improvements, even when they're available. I'm subscribed to the JEuclid mailing list and I get the same impression. This does not work well with JEuclid, though. When JEuclid generates SVG from MathML, it performs font rendering - that is, replaces characters by actual paths. And again, it uses system fonts, not the fonts available in FOP - even if running as FOP plugin. To work around this issue for MathML, I am currently switching from JEuclid to pMML2SVG (http://pmml2svg.sourceforge.net). It generates SVGs with text characters, not paths. But in order to do so, it needs font metrics. Unfortunately, font metrics produced by stock FOP TTFReader are not sufficient - this stylesheet also needs bounding box for each glyph. To obtain these, pMML2SVG currently packages an augmented TTFReader Java sources which are to be compiled and used in lieu of the stock one. Given that the patch is very small and as far as I can tell, compatible with current users of font metrics (it just adds 4 attributes to glyph description), is it possible to integrate this support into stock FOP? Patch from pMML2SVG, slightly modified to apply to FOP 1.1 sources, attached. Thanks for the patch. To get this added to the code base please raise an issue in JIRA, add the diff as an attachment and include [PATCH] in the subject line. A committer will then review the patch before applying it. Created an issue: https://issues.apache.org/jira/browse/FOP-2180 Thank you. I know Peter Hancock is looking into doing something similar as he is working on getting Batik to use FOP configured fonts instead of the system ones. Peter mentioned to me offlist that he was going to need to expose a few extra things in TTFReader to facilitate this, could be you are covering similar ground here. Maybe. Then again, the root of the issue is not Batik - that issue I work around by embedding fonts. It is JEuclid's use of system fonts which is why I am switching to pMML2SVG - which needs bounding box information for glyphs. BTW, another useful feature in pMML2SVG that was not available in JEuclid is that pMML2SVG outputs baseline position information in the generated SVG - so that inline equations can be properly positioned on the line. Sounds like we need a FOP plug-in for pMML2SVG to replace the ageing JEuclid one. Thanks, Chris Regards, Alexey. Anyway, please raise the JIRA issue otherwise your patch could get lost.

Re: targetrenderer set to MIME_PNG fails in fop =1.0 but succeeds in 0.95
Can you start with the embedding.ExampleFO2PDF.java example (in
examples/embedding/java), change the mime type to MIME_PNG (and rename
all the PDFs to PNGs) and confirm that the new example does generate a
PNG file? I just tested that with trunk and it worked.

Dear FOP users,
I'm using FOP for a couple of years now and thought it was time to
upgrade to version 1.1. Problem is that the rendering to PNG stopped
functioning. It all still works with version 0.95.
PDF generation is still fine. The difference between PNG and PDF
generation is the mime type of fop generated with the factory.
Strange thing is that the call to '*userAgent.getRendererOverride()*'
returns 'null' in version 1.1 and returned the expected PNGRenderer in
version 0.95. Is this a bug or is something changed between versions
in relation to PNG rendering?
From the debug info I see that the renderer does create a page. It
seems like the link between the rendererImpl and the mime-type is not
found. But where can I force that?
See code fragments below.
Thank you very much for any help.,

In that case, it probably won't be sufficient: pMML2SVG requires XSLT 2.0, which, as far as I understand, is only supported by Saxon. Regards, Alexey.
