Docsplit is a command-line utility and Ruby library for splitting apart documents into their component parts: searchable UTF-8 plain text via OCR if necessary, page images or thumbnails in any format, PDFs, single pages, and document metadata (title, author, number of pages...)

Docsplit is currently at version 0.5.0.

Docsplit is an open-source component of DocumentCloud.

Usage

The Docsplit gem includes both the docsplit command-line utility as well as a Ruby API. The available commands and options are identical in both.
--output or -o can be passed to any command in order to store the generated files in a directory of your choosing.

images--size --format --pages Ruby: extract_images
Generates an image for each page in the document at the specified resolution and format. Pass --pages or -p to choose the specific pages to image. Passing
--size or -s will specify the desired image resolution, and --format or -f will select the format of the final images.

docsplit images example.pdf
docsplit images docs/*.pdf --size 700x,50x50 --format gif --pages 3,10-15,42
Docsplit.extract_images('example.doc', :size => '1000x', :format => [:png, :jpg])
text--pages --ocr --no-ocr --no-clean Ruby: extract_text
Extract the complete UTF-8-encoded plain text of a document to a single file. If you'd like to extract the text for each page separately, pass --pages all. You can use the --ocr and --no-ocr flags to force OCR, or disable it, respectively. By default (if Tesseract is installed) Docsplit will OCR the text of each page for which it fails to extract text directly from the document. Docsplit will also attempt to clean up garbage characters in the OCR'd text — to disable this, pass the --no-clean flag.

docsplit text path/to/doc.pdf --pages all
docs = Dir['storage/originals/*.doc']
Docsplit.extract_text(docs, :ocr => false, :output => 'storage/text')
pages--pages Ruby: extract_pages
Burst apart a document into single-page PDFs. Use --pages to specify the individual pages (or ranges of pages) you'd like to generate.

docsplit pages path/to/doc.pdf --pages 1-10
Docsplit.extract_pages('path/to/presentation.ppt')
Docsplit.extract_pages('doc.pdf', :pages => 1..10)
pdf Ruby: extract_pdf
Convert documents into PDFs. Any type of document that OpenOffice can read may be converted. These include the Microsoft Office formats: doc, docx, ppt, xls and so on, as well as html, odf, rtf, swf, svg, and wpd. The first time that you convert a new file type, OpenOffice will lazy-load the code that processes it — subsequent conversions will be much faster.

docsplit pdf documentation/*.html
Docsplit.extract_pdf('expense_report.xls')
author, date, creator, keywords, producer, subject, title, length
Ruby: extract_...
Retrieve a piece of metadata about the document. The docsplit utility will print to stdout, the Ruby API will return the value.

docsplit title path/to/stooges.pdf
=> Disorder in the Court
Docsplit.extract_length('path/to/stooges.pdf')
=> 36
