Thanks for the suggestion, Paulo. Unfortunately, I didn't see the svg
on the page. It seemed to create an empty page before my table (my
table used to be the first and only thing in the document, but now
there's an empty page before it). You suggested that my svg might be
off limits, but I don't think that's the case. Here's my simple svg:
<svg width="128" height="128" >
<line x1="5" y1="5" x2="122" y2="122" stroke="rgb(0, 0, 0)" />
<line x1="122" y1="5" x2="5" y2="122" stroke="rgb(0, 0, 0)" />
<text x="15" y="65" stroke="rgb(200, 0, 200)">I curse thee, SVG</text>
</svg>
This svg image shows up fine in the Adobe SVG plugin, and it also works
fine in my little test iText table. Because it worked fine in my test
iText table, I just cut-and-pasted that exact working code where my
current non-functional code was. This code works great in a stand-alone
application, but it also doesn't show any images in my table. What
could possibly interfere with this code which works in an application
all by itself?
Thanks,
Chris

Put here:
img.setAbsolutePosition(0, 0);
cb.addImage(img);
If it shows the image then I'll need a complete runnable example to test
it
here.
If it doesn't the svg is probably off limits.
