About locked PDF files and license files
When you attempt to download or open a PDF file that has been locked,Web Buy will look
for a matching license file. The license file is created by the seller and specifies certain
security and permission parameters. For example, a seller may restrict printing, copying, or
extracting images from a copyrighted document. You can view the security settings for a
PDF file by choosing Document Security from the document pane menu or clicking on the
key icon in the status bar, and clicking the Display Settings button in the Document
Security dialog box. These settings cannot be modified by the user.
If Web Buy is able to locate a valid license file, the locked PDF will be opened for viewing. If
a matching license file is not located, a dialog box will be displayed to allow you to
manually locate the license file on your computer or go online to obtain a license file to
unlock the document.
To find a license file:
1
Click Find License and locate the license file. The license file will have the same name as
the associated PDF file followed by the extension .rmf.
2
Click OK. The PDF will be unlocked and opened.
To obtain a license online:
1
Click Go online. Your browser will open to the URL specified in the locked PDF file.
2
Follow the on-screen instructions to complete the transaction with the seller or source
of the PDF file.
Transacting a purchase using Web Buy
Web Buy is the client (user-end) plug-in that is used to transact with a seller’s server and
open a locked PDF file. Such a transaction may be initiated in a variety of ways, such as
purchasing a PDF directly from an online vendor, or attempting to open a document that
has been distributed free, but which requires the purchase or acquisition of a license file to
open the document. In any case, a typical transaction includes the following steps:
1
In your browser, you will click, Buy, Buy Now, Purchase, or the equivalent.
2
The seller’s server will send a request to Web Buy to provide the required identifier.
3
Web Buy sends the information specified in the Web Buy preferences dialog box to the
seller’s server.
4
If the seller requires additional information, you will be prompted to provide the infor-
mation. Otherwise, the server will send a license file (.rmf ) to the default location you have
specified on your computer.
5
Web Buy will begin to download the PDF document, and prompt you to save the file.
6
When the download is complete, Web Buy will open the document after validating the
file against the previously downloaded license file.
It is important to remember that to open the document, the associated license file must
be present in the same directory as the document you wish to open. If it is not found, you
will be prompted to search for the license file. If the file has been locked using a
removable media, the specified media must also be present.
