I've tested this approach with Firefox 2.0 and rsvg 2.16. The text alignment is actually much better since the text layout is fully under the control of matplotlib. This has been checked into SVN, and can be used by setting the rcparam "svg.embed_char_paths" to True.
The following are my usual "size benchmarks" (that I used for PS and PDF as well): without character paths -> with character paths fonts_demo_kw.py: 10314 -> 69256 mathtext_demo.py: 10606 -> 37896 unicode_demo.py: 7677 -> 43473 over all demos in backend_driver.py: 17,722,815 -> 18,789,999 Cheers, Mike Michael Droettboom wrote: > Actually, it just occurred to me that you could use 'defs' and 'use' to > define characters as paths and reuse them.
