The cb2Bib is a free, open source, and multiplatform application for rapidly extracting unformatted, or unstandardized bibliographic references from email alerts, journal Web pages, and PDF files. The cb2Bib facilitates the capture of single references from unformatted and non standard sources. Output references are written in BibTeX. Article files can be easily linked and renamed by dragging them onto the cb2Bib window. Additionally, it permits editing and browsing BibTeX files, citing references, searching references and the full contents of the referenced documents, inserting bibliographic metadata to documents, and writing short notes that interrelate several references.
Referencer is a Gnome application to organise documents or references, and ultimately generate a BibTeX bibliography file. Referencer includes a number of features to make this process easier: * Smart web links Referencer uses documents' metadata to provide handy links to the document's web location — no need to maintain your own bookmarks. * Import from BibTeX, Reference Manager and EndNote No need to start from scratch — Referencer will import your existing bibliography files using the BibUtils library. * Tagging No need to organise your documents into rigid directory trees — with Referencer you can use tags to categorise your documents. * Automatic arXiv, PubMed and CrossRef metadata retrieval If you show Referencer a PDF which has an arXiv ID or DOI code, Referencer will retrieve the metadata for this document over the internet. * Python plugin support Referencer can be extended using the versatile Python scripting language. * Localisation
The PDF Renderer is just what the name implies: an open source, all Java library which renders PDF documents to the screen using Java2D. Typically this means drawing into a Swing panel, but it could also draw to other Graphics2D implementations. We hope you will come up with cool things to do with it that we never thought of.
PDF is one of the core file formats of the Internet, so it is very important for Java programmers to be able to both read and write PDFs. Great open source libraries like iText have long handled the writing half, but until now there has not been a good way to read PDFs using open source Java libraries. It could be used to draw on top of PDFs, share them over a network, convert PDFs to PNG images, or maybe even project PDFs into a 3D scene.
Removes passwords from viewable PDFs. Does not unlock password protected PDFs. Allows you to combine, modify, and copy text to the clipboard from PDF files which have locked out editing and copying functions.
