# djvu2hocr(1)

DjVu to hOCR converter

## NAME

djvu2hocr - DjVu to hOCR converter

## SYNOPSIS

**djvu2hocr** \[*option*...\] *djvu-file*

**djvu2hocr** {**--version** \| **--help** \| **-h**}

## DESCRIPTION

djvu2hocr converts hidden text from a DjVu file to the *hOCR*\[1\] format.

## 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.

- **--word-segmentation=uax29**

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

### HTML output options

- **--title=***title*

  Specifies the document title.

  The default is “DjVu hidden text layer”.

- **--css=***style*

  Add the specified CSS style to the document.

  For example, **--css='.ocrx\_line { display: block; }'** can be used to visually preserve line breaks.

### Other options

- **--version**

  Output version information and exit.

- **-h**, **--help**

  Display help and exit.

## 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\>
