The Kobo specification page for the Glo (https://www.kobo.com/koboglo/techspecs/) proclaims:


The Kobo devices are listed by Wikipedia and other references as capable of reading EPUB.

But the spec for EPUB 2.0.1 (http://idpf.org/epub/201) and OPS (http://www.idpf.org/epub/20/spec/OPS_2.0.1_draft.htm), clearly states "OPS Reading Systems must support SVG [except animation and scripting features]". And "rotate" and "dy" are among the basic attributes of SVG. So if SVG's "rotate" and "dy" are not supported, EPUB is not supported.

Attached is a bare-minimum EPUB "KoboGlo Bug Demo" which passes epubcheck:

- dogmatix:fix> /usr/local/bin/run_epubcheck kgbd.epub
- Epubcheck Version 3.0.1
-
- Validating against EPUB version 2.0
- No errors or warnings detected.

This EPUB demonstrates SVG's "rotate" and "dy". It is a simple test case for post 418 on this forum. It displays normally on most EPUB readers, but demonstrates faults of KoboGlo.
Ummm... I loaded your test case file in ADE both on a Mac using OS X 10.9 and a Windows computer (Win7 SP1, x64). The display for the dy was crap on both.

I've attached a screen shot of ADE displaying the dy page which, oddly enough, looks pretty much identical to what I see on my Aura using the Adobe RMSDK though forcing use of the ACCESS renderer does seem to display the pages properly -- see the screen captures for those as well.

Regards,
David
