NAME
vprerex - graphical front-end and viewer for the prerex(1) prerequisite-chart editor SYNOPSIS
vprerex basefile[.tex] [ chartfile[.tex] ] vprerex file.pdf vprerex DESCRIPTION
vprerex (visual prerex) is a GUI front-end and viewer for the prerex(1) interactive editor of prerequisite-chart descriptions in the pre- rex(5) format. The viewer may be used just as a minimalistic viewer of arbitrary PDF files but supports editing of charts generated using prerex.sty(7) by allowing coordinates of course boxes, arrows, and background points to be conveyed back to the prerex(1) command-line using the clipboard. USAGE
If vprerex is invoked on a PDF file, it simply displays that file. If the (first) argument does not have the .pdf suffix, it is assumed to be the base file for a LaTeX document containing a prerequisite- chart description in prerex(5) format, to be edited using prerex(1). If a second argument is supplied, it is regarded as an included file containing the specific chart environment to be edited. If no arguments are supplied, a file-opening dialog allows the user the specify the prerex(1) base file to be edited (or the PDF file to be viewed); if a separate chartfile is needed, vprerex(1) must be invoked wth two arguments on the command line. If the mouse hovers over a hyperlink in the PDF viewing window, the cursor shape will change to a pointing finger and a tooltip will dis- play the URI. If the PDF file displayed contains a chart generated using prerex.sty(7) and the background coordinate grid has been enabled, left-clicking the mouse on a course box, arrow mid-point, or background point will load the relevant coordinates into the X clip- board. The cursor shape changes to a plus-sign to indicate successful capture of the coordinates. Middle-clicking the mouse at the pre- rex(1) command-line will then paste those coordinates into a command being composed. If the chart file is regenerated, the updated docu- ment will be re-loaded. DEPENDENCIES
vprerex is based on the Qt-4 library. It calls xterm(1) and prerex(1) for the editing window and uses poppler-qt4 for rendering PDF files. AUTHOR

NAME
CAM::PDF::Decrypt - PDF security helper LICENSE
See CAM::PDF. SYNOPSIS
use CAM::PDF; my $pdf = CAM::PDF->new($filename); DESCRIPTION
This class is used invisibly by CAM::PDF whenever it detects that a document is encrypted. See new(), getPrefs() and setPrefs() in that module. FUNCTIONS
$pkg->new($pdf, $ownerpass, $userpass, $prompt) Create and validate a new decryption object. If this fails, it will set $CAM::PDF::errstr and return undef. $prompt is a boolean that says whether the user should be prompted for a password on the command line. $self->decode_permissions($field) Given a binary encoded permissions string from a PDF document, return the four individual boolean fields as an array: print boolean modify boolean copy boolean add boolean $self->encode_permissions($print, $modify, $copy, $add) Given four booleans, pack them into a single field in the PDF style that decode_permissions can understand. Returns that scalar. $self->set_passwords($doc, $ownerpass, $userpass) $self->set_passwords($doc, $ownerpass, $userpass, $permissions) Change the PDF passwords to the specified values. When the PDF is output, it will be encrypted with the new passwords. PERMISSIONS is an optional scalar of the form that decode_permissions can understand. If not specified, the existing values will be retained. Note: we only support writing using encryption version 1, even though we can read encryption version 2 as well. $self->encrypt($doc, $string) Encrypt the scalar using the passwords previously specified. $self->decrypt($doc, $string) Decrypt the scalar using the passwords previously specified.
