OPTIONS
Input selection options
-p, --pages=page-range
Specifies pages to covert. page-range is a comma-separated list of sub-ranges. Each
sub-range is either a single page (e.g. 17) or a contiguous range of pages
(e.g. 37-42). Pages are numbered from 1.
The default is to convert all pages.
Text segmentation options
--word-segmentation=simple
Use the same word segmentation as found in the DjVu file.
This is the default.

Use the Unicode Text Segmentation[2] algorithm to break lines into words, possibly
fixing word segmentation found in the DjVu file.
HTML output options

Specifies the document title.
The default is “DjVu hidden text layer”.
--css=style
Add the specfied CSS style to the document.
For example, --css='.ocrx_line { display: block; }' can be used to visually preserve
line breaks.

PORTABILITY
djvu2hocr uses a custom extension to hOCR to retain characters which cannot be directly
represented in an HTML/XML document. For example, control character BEL (^G, U+0007), is
converted into the following HTML chunk: <span class="djvu_char" title="#x07"> </span>
