Brian: The XPDF home page at http://www.foolabs.com/xpdf/cracking.html says the following: "If any security features are turned on by the creator of a PDF document, the PDF file will be encrypted. These security features let an author disallow printing, copying text/graphics, editing, and/or adding annotations. "The Xpdf package honors these permission settings. Specifically: * xpdf will not copy/paste from a PDF file which disallows copying text/graphics * xpdf and pdftops will not print (convert to PostScript) a PDF file which disallows printing * pdftotext will not convert a PDF file which disallows copying text/graphics * pdfimages will not extract images from a PDF file which disallows copying text/graphics "I occasionally get email asking if I can explain how to crack a PDF file, or if I can help decrypt a PDF file. I won't help these people because I believe that an author's requests relating to the use of his/her work should be honored." Of course, there are patches out there to inhibit these restrictions and a soon to be published paper from AFB will demonstrate that people who are blind have the legal right in the U.S. to circumvent such measures. Some of these patches are referenced at the page entitled "A Gallery of Adobe Remedies," which is at http://www-2.cs.cmu.edu/~dst/Adobe/Gallery/, though I have not succeeded in getting the ones I've tried to work. Are you saying that the Debian distribution of XPDF inhibits these restrictions by default? On Sat, 2 Mar 2002, Brian Borowski wrote: > There are no problems in converting this book.
