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=widthxheight
-
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.
