# hocr2djvused(1)

hOCR to djvused script converter

## NAME

hocr2djvused - hOCR to **djvused** script converter

## SYNOPSIS

**hocr2djvused** \[*option*...\] \[*hocr-file*...\]

## DESCRIPTION

hocr2djvused reads one or more *hOCR*\[1\] files (as produced by *OCRopus*\[2\] or *Cuneiform*\[3\] or *Tesseract*\[4\]) and converts them to a **djvused** script.

Unless a filename is explicitly provided on the command line, hOCR is read from the standard input.

## OPTIONS

### Text segmentation options

- **-t lines**, **--details lines**

  Record location of every line. Don't record locations of particular words or characters.

- **-t words**, **--details=words**

  Record location of every line and every word. Don't record locations of particular characters.

  This is the default.

- **-t chars**, **--details=chars**

  Record location of every line, every word and every character.

- **--word-segmentation=simple**

  Consider each non-empty sequence of non-whitespace characters a single word.

  This is the default, despite being linguistically incorrect.

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

  Use the *Unicode Text Segmentation*\[5\] algorithm to break lines into words.

  This options break assumptions of some DjVu tools that words are separated by spaces, and therefore is it not recommended.

### Other options

- **--rotation=***n*

  Assume that DjVu pages are rotated by *n* degrees.

- **--page-size=***width***x***height*

  Specifies that page size is *width* pixels × *height* pixels.

  This option is required for hOCR generated by Cuneiform (\< 0.8) and superfluous otherwise.

- **--html5**

  Use a *HTML5 parser*\[6\], which is more robust but slower than the default parser.

- **--fix-utf8**

  Attempt to fix UTF-8 encoding issues and eliminate unwanted control characters.

  This option might be needed for hOCR generated by Cuneiform\[7\] or Tesseract\[8\].

- **--version**

  Output version information and exit.

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

  Display help and exit.
