First I am using the default reader (fbreader and pdf reader for TXT and EPUB). I tried to add more control by myself and now want to share some experience.
Tools: OTFM and any editer you like (notepad++ as an example). If you want you can begin with OTMF alone, even for editing on the fly (thanks to the author for creating such a great tool
!).
Part I (TXT reader)
/root/onyx_reader/ui.xml
Sample:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<group name="Indicator">
<option name="FontSize" value="24"/>
</group>
<group name="Options">
<option name="BottomMargin" value="8"/>
<option name="LeftMargin" value="8"/>
<option name="RightMargin" value="8"/>
<option name="TopMargin" value="8"/>
</group>
<group name="Style">
<option name="Base:fontFamily" value="YourFontName"/>
<option name="Base:fontSize" value="34"/>
<option name="Base:lineSpacingPercent" value="125"/>
<option name="Regular Paragraph:spaceAfter" value="4"/>
<option name="Regular Paragraph:spaceBefore" value="4"/>
</group>
</config>
What we have:
- Better control for the page margin
- Better control for the line spacing
- Control for paragraph spacing ("Regular Paragraph:spaceAfter" and "Regular Paragraph:spaceBefore")
If you use fbreader for epub reading I guess you can have more control by yourself.
