Hi Bill
I found this message that had code to redirect from a JTextPane to
iText. I didn't see any z-order in it.

This is the critical snippet.
// a JTextComponent makes a copy of any graphics you pass to it
and then paints itself last.
// this fix makes the JTextComponent paint when you want it to,
not when it wants to.
Rectangle alloc = getVisibleEditorRect(ta);
ta.getUI().getRootView(ta).paint(g2, alloc);
Thanks very much for that piece of code. It rescued me big time.
However, we seem to be operating with different values of trivial :)
Also I have not explained myself clearly enough.
I am using a variant of the above code to put the text in the pdf file
but I am using the iText Image class to put the images in a PdfTemplate
object which then get added to the page. I was using awt.Image but it
lost resolution so I couldn't use it to print. I am still using it on
the screen. The text itself always appears over the images in the pdf
file (until I clipped the text), however the text background is under
the images. The z-ordering is correct on the screen (I am using
JLayeredPanes there, one to hold the whole screen and one each for each
text or image element, which also holds drag and resize handles);
The clipping solution won't work for images with transparent
backgrounds. These are unlikely/rare but it would be good if they worked.

pdf with iText. If you do it right, it is trivially easy. It gives
instructions on
how to get around the z order problem. It is not a design decision, but
rather a
feature/bug of JTextPane. I am mobile right now, but I can send you the
code later today.
