WritebookPdfImport

A Rails engine that adds PDF import support to Writebook. It parses a PDF and creates Page and Picture leaves in a book.

Usage

An Import PDF button is added to the book page, allowing you to upload a PDF directly from the Writebook interface.

Installation

Add to your Gemfile:

gem "writebook_pdf_import"

What it does

• Extracts text from each PDF page and creates a Page leaf
• Extracts embedded images (JPEG, JPEG 2000, raw RGB/grayscale/CMYK) and creates Picture leaves
• Uses the first line of text as the page title if it's 3–100 characters, otherwise falls back to "Page #"
• Skips blank pages

Dependencies

• pdf-reader ~> 2.12
• mini_magick (for JPEG 2000 and raw image conversion)
• ImageMagick must be installed on the system

Background Jobs

PDF imports are processed asynchronously using Active Job. You must have Redis and a Solid Queue worker running:
