--extract-to
Extract the contents ofthe generated EPUB file to the specified directory. The contents of the directory are first
deleted,so be careful.
--flow-size
Split all HTML files larger than this size (in KB).This is necessary as most EPUB readers cannot handle large
file sizes. The default of 260KB is the size required for Adobe Digital Editions. Set to 0 to disable size based
splitting.
--no-default-epub-cover
Normally, if the input file has no cover and you don’t specify one, a default cover is generated with the title,
authors, etc. This option disables the generation of this cover.
--no-svg-cover
Do not use SVG for the book cover. Use this option if your EPUB is going to be used on a device that does not
support SVG, like the iPhone or the JetBook Lite. Without this option, such devices will display the cover as a
blank page.
--preserve-cover-aspect-ratio
When using an SVG cover, this option will cause the cover to scale to cover the available screen area, but still
preserve its aspect ratio (ratio of width to height). That means there may be white borders at the sides or top
and bottom of the image, but the image will never be distorted. Without this option the image may be slightly
distorted,but there will be no borders.
--pretty-print
If specified, the output plugin will try to create output that is as human readable as possible. May not have any
effect for some output plugins.
--toc-title
Title for any generated in-line table of contents.
