Thanks for that Cameron, will give those suggestions a run and let you know, thanks. Yes, the sylesheets are external to the SVG Document, included as resource in a WAR file, maybe that’s where the problem lies when using SSL.
We have just uploaded the same source to the test environment of the customer (where the SSL and certificates are set up correctly, though this may still be a red herring!) and everything is fine. Agreed, impossible to elicit any further information without setting up a reproducible test case, so I'll look at that now and post it when I get something useful.

If your stylesheets are external, then I guess that could be an issue. What if you set the font-size within the document itself? getBBox() should return a tight bounding box of the union of all of the glyphs rendered by the <text> element. So yes, if the font size is different, the bounding box will be different. > I should point out that the initial failure is occuring when we create a > document in memory which is never actually rendered, to this we add > components (mostly Text) with given styles to assess their dimensions, > and using those dimensions we assess our layout. > > When we view the final SVG, the styles are applied fine, and everything > is as expected, except for a downward shift in the locations of most > components. What about if you put text-rendering="geometricPrecision" on the document element? Does that give you consistent results? I think we may need to see a reduced test case that demonstrates the problem to be able to help much further.
