Dear Xara...

Xara Desktop applications can claim superior quality in rendering due to its vector base, sub-pixel anti-aliasing and the use of fonts for rendering on the web page.
All this pops when text is placed on a path. On publish, I get a low resolution image of a text line or box that when scaled shows jaggies very readily.

I can convert to editable shape but lose the text-editing capability.
Also, the resolution of the grouped shapes is no better that above.

All looks well in the Xara design page.

I can create a bitmap copy but have to go to ludicrous dpi values and large upload file sizes for little benefit.

My suggestion is reliant on the use of known letter placement and CSS3 transforms. Each glyph would have to be processed individually.

The benefit, however, would accrue once you could also apply other effects dynamically through class interactions.
I would expect there to be a character limit as rendering an entire page of single letters would be a chore.
