Thanks for that. We will look into the impact of using an SVG font as a matter of urgency.
Further info.... it seems like the bounding box of a text element is being returned as the same dimensions regardless of the font-size that is applied. This suggests it is assuming the default font-size? Suggesting that the font-size in the CSS is not being picked up? We are currently using SSL in our own environment, where our certificates may not be set up completely correctly. Is it possible that when we use getBBox() there is a refusal in a handshake somewhere along the line, so the stylesheet is not accessible? And thus all the bBoxes are not assessed correctly? Does getBBox work like that. The baseUrl of the document is set using the current URL so that would https://blahblah/, if that is relevant. 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. Many thanks for the replies so far, Dylan. -----Original Message----- From: Andreas Neumann [mailto:[EMAIL PROTECTED] Sent: 16 October 2007 20:23 To: [email protected] Subject: Re: Text shift during export to PNG 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. Andreas Dylan Browne wrote: > > Hi all, > > Thanks for the updates.
