In discussing this bug with a friend, he reminded me that, in the "flash and escape" phototypesetters, when you wanted to change the aspect ratio of a letterform, you has to set anamorphic magnification. It appears that InkScape has a habit of using complex scaling algorithms to effect this anamorphic magnification. This could well be confusing some of the image renderers. Looking at the XML coding, Inkscape sometimes changes the font height, then changes Y magnification to compensate. Sometimes it doesn't. This may be the root cause of the bug.
Any road, the issue is that each letterform in a variable-width font has an image, and a width value (sometimes called "escapement", harkening back to the days of the spinning-disk optical phototypesetters where the paradigk was "flash and escape".) The width values are not being scaled properly. This is most likely a simple oversight, and if so it's easy to fix. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to eog in Ubuntu. https://bugs.launchpad.net/bugs/2059817 Title: Image viewer renders SVG improperly Status in eog package in Ubuntu: New Bug description: Image viewer fails to render SVG images with transform matrices that are no equal.

The letterspacing used appears to be the full-size glyph width in the font. In another test, where the text is stretched, the individual glyphs are appropriately stretched, but letterspacing is not. The letterspacing used appears to be the full-sized (unstretched) glpyh width in the font.
