Re: EmptyStackException when processing embedded svg flowRoot
element
Andrew,
Which version of Apache FOP are you using? Could you post a FO document
where you have svg:flowRoot working?
Using this document;
<?xml version="1.0" encoding="ISO-8859-1"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:layout-master-set>

page-width="210mm">
<fo:region-body margin-bottom="10mm" margin-top="10mm"/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence font-family="times" font-size="10pt"

<svg:flowDiv>
<svg:flowPara>Tomorrow, and tomorrow, and
tomorrow; creeps in this petty pace from day to day, until the last syllable

</svg:flowDiv>
</svg:flowRoot>
</svg:svg>
</fo:instream-foreign-object>
</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
I keep on getting "The current document is unable to create an element of
the requested type (namespace: http://www.w3.org/2000/svg, name:
svg:flowRoot)." message. After reading
http://www.mail-archive.com/fop-users@xmlgraphics.apache.org/msg11742.html,
I created a custom build of fop-0.95 because in my understanding the current
release does not support/implement SVG 1.2.
I am very suprised to read about your problem, since it seems that I can not
even get at that point.
Thanks,
Ralph

Re: EmptyStackException when processing embedded svg flowRoot
element
Posted by relluf <na...@relluf.nl>.
First off, I solved my issue by using the lastest trunk of fop-0.95.

SVG is processed by Batik, true, but the issue is indeed with FOP. In
current release FOP is not aware of SVG 1.2. The latest trunk is.

In my experience batik-1.7 does render svg:flowRoot "correctly". But then
again, what is correctly, as the standard is still in draft. To verify,
download the lastest binary release of batik-1.7 and open the following
document in batik-squiggle;
<svg:svg xmlns:svg="http://www.w3.org/2000/svg" version="1.2" height="150"
width="100">
<svg:flowRoot>
<svg:flowRegion>
<svg:path d="M100,50L50,300L250,300L300,50z" visibility="hidden"/>
</svg:flowRegion>
<svg:flowDiv>
<svg:flowPara>Tomorrow, and tomorrow, and tomorrow; creeps in this
petty pace from day to day, until the last syllable of recorded time. And
all our yesterdays have lighted fools the way to dusty death.</svg:flowPara>
</svg:flowDiv>
</svg:flowRoot>
</svg:svg>
The latest release of InkScape on the other hand, does fail.

The error is not avoided by that until I started using the trunk of
fop-0.95.

Thanks for the suggestion, but there is no need to. I got things working as
I want now.

SVG is processed by Batik, so this is really a Batik problem not a FOP
one. Batik doesn't properly support svg:flowRoot, which I know Inkscape
uses when generating/editing SVG there. You can avoid the error by
changing the version attribute on the SVG element from 1.0 to 1.2 but
Batik still doesn't draw the flowRoot elements correctly.
I suggest you follow up this issue on batik-users@xmlgraphics.apache.org.
Thanks,
Chris
