Kobo-ising O'Reilly Books

ManicDee · 02-05-2012, 10:36 PM

I'd like to build a "recipe" for Kobo-ising O'Reilly books. The basics so far will be:

Replace O'Reilly's core.css file with a stripped down version
Remove a bunch of headings from the TOC when processing "Cookbook" style books
Shrink & rotate images as required to get them to fit into the Kobo screen in portrait aspect

The current ePub to ePub conversion works, but leaves a stylesheet that is far too complex. The Kobo takes tens of seconds to switch between chapters. In addition, all images are simply scaled down to fit: diagrams lose information due to being squeezed to fit landscape-style in the portrait page of the Kobo.

Is this something I should be trying within Calibre, or should I just stick to writing my own stand-alone filter to do the Kobo-isation?

I certainly don't know enough to help you, but I also have a problem running ePubs I design on a Kobo - none of the HTML links work, and Kobo 'Help' refuses to help. So if you find out out to make links in 3rd party ePubs work on a Kobo please let us know.
