Made e-book more readable with Sigil
====================================
Yesterday I started reading an new e-book. Unfortunately, all text
was bold.
My e-reader comes with the option to select a different font, but
no matter what I choose, the text remained bold, only with a
different font.
To test if this was a problem of my e-reader, I opened the
epub file in mupdf. Mupdf also showed all text in bold.
ebook-convert
-------------
The Calibre package comes with a command line tool, called
`ebook-convert'.
I tried to filter out the css with ebook-convert, but that didn't
help.
Then I remembered having once reviewed Sigil, which is a wonderful
open source application for creating high quality epub files.
Sigil
-----
I installed Sigil, using FreeBSD's package manager, and opened the
e-book with it.
Sigil said it repaired the e-book, apparently it was not compliant. I
opened the repaired book in mudpf, but still all text was bold.
Next, I opened the book in Sigil again. It starts by showing the CSS
file, and this started with an entry for 'bold'. I removed this, saved
the epub file again.
And there was much rejoicing ...
Now mupdf showed normal text, not bold.
I removed the original epub file from my e-reader, uploaded the newly
created one, and yes, the e-reader also showed normal text, nothing
bold anymore.
