Status: RESOLVED DUPLICATE of bug 308338

(Core :: SVG, defect)

I was attempting to create a text object with a superscript <tspan>, but I found that vertical-align is ignored.  According to http://www.w3.org/1999/08/WD-SVG-19990812/text.html#propdef-vertical-align, vertical-align is valid on a tspan.

(I found that Inkscape is having problems with and baseline-shift.  Someone might want to test that.  See https://bugs.launchpad.net/inkscape/+bug/478737 for more information on Inkscape's problems.)

Reproducible: Always

Steps to Reproduce:
1. View any file that has vertical-align applied to a tspan
2.
3.
Actual Results:  
Firefox will display the tspan's text, but aligned vertically incorrectly.

Expected Results:  
With the attached sample, I should get superscript text.  With other vertical-align values, they should be obeyed.

BTW: I list x86_64 as my platform.  However, that refers to my OS, not my FF build.

I can provide a full config on request.

Attachment: Simple SVG with an attempt at superscript (the "st" part of the string is its own tpsan)

Comment 2

[Will Pittenger]

I am told that vertical-align for SVG never made it to recommendation.  So I am replacing the sample.

Attachment: New sample uses baseline-shift instead of vertical-align; look at the "st" part of the string.
