With the demise of the Sony reader, and the unavailability and uncertainty of the Nook, Kobo readers have become the leading eink devices for reading EPUBs.
The Kobo specification page for the Glo (
https://www.kobo.com/koboglo/techspecs/) proclaims:
Quote:
OPEN Read almost any eBook on your Kobo Glo. Supports ePub and Adobe DRM
File Types EPUB, PDF, JPEG, GIF, PNG, TIFF, TXT, (X)HTML, RTF, CBZ, CBR
|
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.
