All Implemented Interfaces:

FormatFilter

public class XPDF2Text
extends MediaFilter

Text MediaFilter for PDF sources This filter produces extracted text suitable for building an index, but not for display to end users. It forks a process running the "pdftotext" program from the XPdf suite -- see http://www.foolabs.com/xpdf/ This is a suite of open-source PDF tools that has been widely ported to Unix platforms and the ones we use (pdftoppm, pdftotext) even run on Win32. This was written for the FACADE project but it is not directly connected to any of the other FACADE-specific software. The FACADE UI expects to find thumbnail images for 3D PDFs generated by this filter. Requires DSpace config properties keys: xpdf.path.pdftotext -- path to "pdftotext" executable (required!)
