Presentation

This project provides some tools that help the user to extract structured information from PDF documents. Currently, the program is able to export them to HTML.

PDFJuice depends on Apache PDFBox to read PDF documents.

There are two functionalities available so far:

• Extract tables.
• Extract slides.

This project is a spin-off of Courseminer.

Compile

Compile with dependencies:

mvn compile package assembly:single

Usage

Generate examples:

Output files are already available in the repository. They will be overwritten.

java -cp target/PDFJuice-1.3-SNAPSHOT-jar-with-dependencies.jar org.sj.tools.pdfjuice.ExampleGenerator

Use graphic user interface

See this tutorial.

Run from command line

java -cp target/PDFJuice-1.3-SNAPSHOT-jar-with-dependencies.jar org.sj.tools.pdfjuice.PDFJuice -m [mode] -i [input-filename] -o [output-filename]

The mode option may be slide or table, depending on which kind of information you want to extract (text and poster modes are under development).
