HOCR2DJVUSED(1) hocr2djvused manual HOCR2DJVUSED(1)NAME
hocr2djvused - hOCR to djvused script converter
SYNOPSIS
hocr2djvused [option...]
DESCRIPTION
hocr2djvused reads a hOCR[1] file (as produced by OCRopus[2] or Cuneiform[3] or Tesseract[4]) from the standard input and converts it to a
djvused script.
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 x 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.
--version
Output version information and exit.
-h, --help
Display help and exit.

Text::Wrap - line wrapping to form simple paragraphs
SYNOPSIS
Example 1
use Text::Wrap
$initial_tab = " "; # Tab before first line
$subsequent_tab = ""; # All other lines flush left
print wrap($initial_tab, $subsequent_tab, @text);
print fill($initial_tab, $subsequent_tab, @text);
@lines = wrap($initial_tab, $subsequent_tab, @text);
@paragraphs = fill($initial_tab, $subsequent_tab, @text);
Example 2
use Text::Wrap qw(wrap $columns $huge);
$columns = 132; # Wrap at 132 characters
$huge = 'die';
$huge = 'wrap';
$huge = 'overflow';
Example 3
use Text::Wrap
$Text::Wrap::columns = 72;
print wrap('', '', @text);
DESCRIPTION
"Text::Wrap::wrap()" is a very simple paragraph formatter. It formats a single paragraph at a time by breaking lines at word boundries.
Indentation is controlled for the first line ($initial_tab) and all subsequent lines ($subsequent_tab) independently. Please note: $ini-
tial_tab and $subsequent_tab are the literal strings that will be used: it is unlikley you would want to pass in a number.
Text::Wrap::fill() is a simple multi-paragraph formatter. It formats each paragraph separately and then joins them together when it's
done. It will destory any whitespace in the original text. It breaks text into paragraphs by looking for whitespace after a newline. In
other respects it acts like wrap().
OVERRIDES
"Text::Wrap::wrap()" has a number of variables that control its behavior. Because other modules might be using "Text::Wrap::wrap()" it is
suggested that you leave these variables alone! If you can't do that, then use "local($Text::Wrap::VARIABLE) = YOURVALUE" when you change
the values so that the original value is restored. This "local()" trick will not work if you import the variable into your own namespace.
Lines are wrapped at $Text::Wrap::columns columns. $Text::Wrap::columns should be set to the full width of your output device. In fact,
every resulting line will have length of no more than "$columns - 1".
It is possible to control which characters terminate words by modifying $Text::Wrap::break. Set this to a string such as '[s:]' (to break
before spaces or colons) or a pre-compiled regexp such as "qr/[s']/" (to break before spaces or apostrophes). The default is simply 's';
that is, words are terminated by spaces. (This means, among other things, that trailing punctuation such as full stops or commas stay
with the word they are "attached" to.)
Beginner note: In example 2, above $columns is imported into the local namespace, and set locally. In example 3, $Text::Wrap::columns is
set in its own namespace without importing it.
"Text::Wrap::wrap()" starts its work by expanding all the tabs in its input into spaces. The last thing it does it to turn spaces back
into tabs. If you do not want tabs in your results, set $Text::Wrap::unexapand to a false value. Likewise if you do not want to use
8-character tabstops, set $Text::Wrap::tabstop to the number of characters you do want for your tabstops.
If you want to separate your lines with something other than "
" then set $Text::Wrap::seporator to your preference.
When words that are longer than $columns are encountered, they are broken up. "wrap()" adds a "
" at column $columns. This behavior can
be overridden by setting $huge to 'die' or to 'overflow'. When set to 'die', large words will cause "die()" to be called. When set to
'overflow', large words will be left intact.
Historical notes: 'die' used to be the default value of $huge. Now, 'wrap' is the default value.
EXAMPLE
print wrap(" ","","This is a bit of text that forms
a normal book-style paragraph");
