hm - this seems to be very unlikely. I don't see why the protocol used
should influence the SVG rendering.
Can't there be another cause?
Font issues or whitespace are much more likely to be the cause. Just
because a font is installed on a system, it doesn't necessarily mean
that Batik is using it. To be on the safe side with fonts, I recommend
the use of SVG fonts.
Can you create a very small example illustrating the issue? if possible
without any complex scripting or serverside scripting.

Hi all,
Thanks for the updates. I have one myself…. which is straying slightly
off-topic, (and may potentially be becoming non-Batik so apologies if
so), but the two may be linked.
We have now noticed shifting in rendering of SVG (not the PNG export
specifically) when we generate over SSL and when we generate over
plain HTTP.
The SVG is rendered correctly in precisely the dimensions and
locations specified by the values provided, so no problem there. But
the calculations as to where things should be located in the display
are returning different values depending on the protocol, that is,
different in HTTP and HTTPS.
It appears the calculation of the height of text is somehow behaving
differently, though this could be a red herring, when retrieving the
bounding box. Apologies for being vague, if/when further details
become clear I will post them. In the meantime, if this rings any
bells with anyone, all help gratefully received.
Best regards,
Dylan

*Subject:* Re: Text shift during export to PNG
This is probably not the problem but... I've seen text "shifting" in
the past when I wasn't being careful about whitespace.
E.g., if the XML files are identical, but one has more or less
whitespace inside a <text> tag, then the text can shift because of the
extra space.

Same fonts are used on server. I have tried this on PC and Linux. The
same shifting occurs on both. I have also tried different fonts with
the same shifting.

Hi Greg,
Thanks for that, good to know we are not alone! ;)
Does anyone have any more specific info about this... my concern is that
it is not consistent between machines/environments (though within a
single machine/environment it is consistent).
Grateful for any help,
Dylan.

I seem to have this problem as well. It seems to show up differently at
different locations on the screen for me. It looks as if it is a
positional rounding issue for text.
