Would someone who knows please enlighten me as to why it is one could not modify an open-source program which can view PDF files which are "encrypted" and which are marked as not printable to ignore the "no print" specification? Specifically, is the GNOME PDF viewer open source? If so, then what prevents one from modifying it to ignore the "no print" lock? If a specific license is required for opening/using PDF files, then how can there be open source programs which can read it? If the GNOME PDF viewer is not open source, then how is it distributed all over the Linux world? I understand that PDF is an open standard, but the Wikipedia also says it is proprietary. How can an open standard be proprietary? Mike -- p="p=%c%s%c;main(){printf(p,34,p,34);}";main(){printf(p,34,p,34);} This message made from 100% recycled bits. You have found the bank of Larn. I can explain it for you, but I can't understand it for you. I speak only for myself, and I am unanimous in that!
