HOCR2DJVUSED(1) hocr2djvused manual HOCR2DJVUSED(1)

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.
