It appears you are right. However I don't think we are apt to fix this
as SVG 1.2 changed directions after we implemented this. Post
Batik 1.6 we updated the flowDiv/flowPara elements to implement the
TextContent interface. So you can get the bbox of individual chars
which you could use to build this up.
OK, thanks... I still have more questions :-/
1) From what I could scrounge up, it looks like textContent is just a
string. How does that help?
2) I can alert() the textContent of the <flowPara> element... and it
does appear to be just a string...?
3) Yes, I did have to build Batik from trunk to get that... but then,
my image didn't display correctly; all I got was a black rectangle. If
I add style="fill: white" on the <rect>, then I can see my text again...
but I don't really want a white background, I need a transparent
background. How do I make that happen? (Sorry, I don't really know
SVG, I'm just bumbling along).
I have to admit that all this is a wee bit discouraging... "All I Want
To Do"(TM) is render some text and have the hight of the graphic be
constrained to the height of the wrapped text. It seems like that
should be dead simple, but it turns out that SVG has no concept of this,
and I need to write an onload handler to fixup the container size. OK,
no problem... oh, but wait, it's not as easy as just asking for a
bounding box anymore, now you have to walk over the glyphs and calculate
that yourself... This feels like punishment for what must be some abuse
of SVG, or else... is it a bad sign when the very first thing a clueless
newbie wants to do with SVG turns out to require "esoterica" to get it
working? (It feels like something in the same league as HTML+CSS not
supporting vertical centering or grid layouts).
OK, whiney rant over. Getting this working is the only thing holding up
a web site launch that's already late, so... you know :-). Anyway, I
can see that the flowPara element has a textContent attribute but I have
no idea how to use that to build up a composite bounding box (as it
appears this attribute is just a string). Any help is much appreciated!
Thanks,
