Thanks for your response Helder. Yes, the shapes are correct.
It is entirely possible that the heart of the issue lies in the SVGs I
am attempting to render. However when I load this same SVG back into
Illustrator or The Gimp or any web browser it renders without the
vertical gaps. Only with Batik do I get these anomalies.
This leads me to believe there is something unique in Batik's anti-
aliasing technique that, in this case, does not work to my favor.
The only quick fix I can think of is to rasterize the SVG (with
crispEdges) at a very high resolution and then resize it to the
resolution I need using bicubic resampling from an image library to
get a pseudo-antialiased rendering.

I have an SVG file:

therefore *any* help would be greatly appreciated.
The file itself seems a bit broken. The shapes within the file don't
make much sense and there is a number of vertical lines which seem to
be causing this symptom. Try setting 'stroke="blue"' in the "main"
group ("g" element), which will highlight the contour of shapes, to
see what's going on...
There have been a number of reports that the SVG export plug-in of
Adobe Illustrator has a few issues. Nevertheless, by looking at the
file, it seems as if someone had tried to vectorize a preexistent
file, due to the large number of weird curves (try zooming in a couple
of times). Is this the case? Are the shapes within the original file
correct?
I'm not arguing about the geometric precision of Batik - I believe
this should be further investigated to check for a lack of precision
(in Batik or Illustrator?), possibly a content issue, etc...
Finally, I've confirmed that using "crispEdges" seems to workaround
the issue. I'm using Java 6 update 7 on Windows XP SP3 and Squiggle of
both Batik 1.7 release and of the latest nightly build [1].
