In the example is a screenshot of GDI+ version added using <image xlink:href="...png"/> It looks like all the pixels that are used for antialiasing are completly black. Reproducible: Always Expected Results: is added to the SVG as PNG

Test case # It contains some Japanese characters. # Maybe you'll need the 'MS Gothic' font.

Screenshot on Official Firefox 1.5 Beta 2.

Screenshot on trunk contrib GDI+ build.

Is this still an issue with current trunk builds?

There is still a problem in Firefox 1.5.0.2. Example: <svg xmlns="http://www.w3.org/2000/svg"> <g transform="rotate(10)"> <text x="20" y="20" font-size="15" >Project</text> </g> </svg>

Yes, but I asked about trunk builds. Nothing is going to change in layout or rendering in the 1.5.0.x builds -- those are security releases.

Now I tested minefield 3.0a1 - same problem If a group that contains a text is rotated, the antialiazing does not work properly. Text on textPath works fine including antialiazing - that's nice to see!

This still seems to be an issue in the current trunk: here is another example where transformed SVG text doesn't use or uses very ugly antialiasing: http://www.carto.net/neumann/mozillasvgbugs/svghearts_static.svg

The content is pretty vile as well

You can also notice that the font-size is not correctly rendered

Both the attached test case and the linked 'svghearts' test appear properly anti-aliased on FF3.0b3 on OS X. FWIW, the svghearts test (but not the attachment) does appear aliased for all the rotated text in Safari 3.0.4

Is this bug still present? The text looks good to me on Mac at least.

SVG sweethearts still looks bad for me on windows XP with current 1.9.2 nightly

SVG hearts still looks bad on Windows XP and the latest current nightly. On MacOSX 10.5 it looks fine. Will taster later on Linux as well. Andreas

This was logged by a windows user - might have always been windows specific ?

Fixed on trunk provided you have Vista or Windows 7 and direct write is enabled (gfx.font_rendering.directwrite.enabled = true)

Realistically, nobody is going to work on fixing cairo's text rendering on Windows XP. The plan with Asure (bug 651857) is to stop using cairo. See bug 703159 for switching the SVG code to use Azure. I'll mark this as dependent on that bug for now to remind us to revisit this bug after that's done.
