Introduction

Parameters or "Embedded Commands"  can be entered into the originating document to instruct pdfMachine on particular actions to take when generating the PDF.

e.g.  If the text:

 #_ savePDF C:\tmp\savedfile.pdf _#

 appears in a Word document and it is printed to pdfMachine with parameter parsing enabled the file will be automatically saved to c:\tmp\savedfile.pdf and no pdfMachine user interface will be displayed.


If parameter parsing is enabled, pdfMachine will parse the PDF file for the specified parameters listed above and described in detail below. These parameters control both the content of the generated PDF file (eg inserting images, replacing keywords with text) and the way that pdfMachine works (eg setting passwords, emailing the PDF, saving the PDF).

This is particularly useful for integration with legacy software to do "mail merge" type operations.

WARNING: Parameters in pdfMachine can be very powerful and complex.  Please test each configuration thoroughly before using in a production environment.
 

How to use Parameter Parsing

1) Turn it on

Check the "Enabled" check box in the Parameter Parser tab of the pdfMachine Options dialog to turn parameter parsing on.  Enabling parameters will slow processing of pdfMachine down a little, so don't do it unless you need them.

After parsing the parameters pdfMachine will either remove from or leave in the parameters from the resultant PDF file as selected by the radio buttons in this dialog.

The parameter parsing is done using the "Perl-Compatible Regular Expressions" library developed by Philip Hazel. A regular expression is a pattern that is matched against a subject string from left to right. For a detailed explanation of regular expressions, please read:

http://home.att.net/~robertdunn/Papers/RegExpSyntax.html


The default regular expression used is: #_ (\w+) (.+?)_#

We recommend this regular expression is not changed without a good understanding of regular expressions. Should this accidentally be changed it  can be corrected using the default regular expression described on this page.

If you need to change the regular expression, it is stored under the following registry entry: 

HKCU\Software\pdfMachine\RegExp
 

The default regular expression will allow parameters to be entered into the originating document in the following format:
#_ parameter argument(s) _#

Note: A parameter and an argument list for that parameter must both be specified, even if the arguments are not used, at least 1 argument must be present.  For example:

A valid entry for setting a digital signature in the PDF file is : #_ digsig 1 _#
An invalid entry for setting a digital signatures is : #_ digsig _#

2) Create the originating document with appropriate parameters

The parameters are not case sensitive. Choose from the parameters listed below:

Sending an email with the PDF Attachment

The following parameters can be used to cause pdfMachine to email the resultant PDF. See example.

Parameter Description
Email Arguments: Comma separated list of email addresses to send to.

e.g. #_ email dave@broadgun.com _#
 
EmailCC Arguments: Comma separated list of email addresses to cc to.

e.g. #_ emailCC dave@broadgun.com _#
 
EmailBCC Arguments: Comma separated list of email addresses to bcc to.

e.g. #_ emailBCC dave@broadgun.com _#
 
EmailSubject Argument: Subject of email

e.g. #_ emailSubject Your invoice is attached _#
 
Emailbody Argument: Text body of email. May span across multiple lines.

e.g. #_ emailBody Hi,
Please find attached a very useful PDF file.
Best Regards,
The Boss. _#

 
EmailAttachmentName Argument: Name to use for attached PDF file

e.g. #_ emailAttachmentName invoice.pdf _#
 
MergeField Arguments: fieldname value

The MergeField parameter allows the contents of the Email to be customized to a finer detail. That is, the subject, body and attachment name can be set in the pdfMachine options screens. The {} characters can be used to define field names within these and then the MergeField parameter used to set these field names. See example.

MergeField can only be used when the Email parameter is set.

Takes a fieldname to replace, and the value to replace that fieldname with. The mergeField is applied to the EmailSubject, EmailBody and EmailAttachment name settings.

e.g. #_ MergeField first_name Fred _#
This will replace all occurrences of {first_name} in the subject, body or attachment name settings, with the word Fred.

Save the PDF File

The following parameter causes pdfMachine to automatically save the resultant PDF file to the specified location.

Parameter Description
SavePdf Argument: Path to the location to save the PDF file

e.g. #_ SavePdf C:\savedFileHere.pdf _#

 

Inserting or Appending PDF Files

The following parameters insert or append files into the resultant PDF file .

Parameter Description
AppendPdf Argument:  Path to the PDF file that is to be appended.

e.g. #_ AppendPDF c:\somefile.pdf _#
Multiple appendPdf parameters can appear in the file which will result in multiple PDF's being appended.

See example
 
InsertPdf Argument:  Page number after which to insert ( 0 to insert at the start of file), path to the PDF file to insert.

See example.
 

 

Encryption

The following parameters cause pdfMachine to enable encryption and to set the appropriate passwords in the resultant PDF file.

Parameter Description
OpenPass Argument: Password required to open the document (a.k.a. user password).
 

e.g. #_ OpenPass mysecret _#


NOTE : Set the other encryption parameters in the pdfMachine options screens.
PermPass Argument:  Permissions password (a.k.a. owner password).

e.g. #_ PermPass mysecret _#

NOTE : Set the other encryption parameters in the pdfMachine options screens.

 

Stationery

Parameter Description
Stationery Arguments: pages drawn path

pages:
all
| first
Optionally specify which pages the stationary is applied:
"all" (default) applies the stationery to all pages of document.
"first" applies it to first page only.
drawn:
below | above
Optionally specify how the stationery is drawn:
"below" (default) draws the stationery underneath the page text.
"above" draws the stationery above the page text.
path Path to PDF file to be used as stationery.


e.g.
#_ Stationery all above c:\stationery.pdf _#
 

Digital Signature

The following parameter causes pdfMachine to Inserts the selected digital signature at the current place in the file.

Parameter Description
DigSig Argument: visible enabled
visible:
show
| noshow
Optionally specify if signature is visible:
"show" (default) shows the signature appearance as specified in the options settings.
"noshow" document is signed but has no signature picture or words.
enabled:
on | off
Optionally specify if signature is done:
"on" (default) signs document.
"off" does not sign document. Allows you to override digsig being enabled in the options. 

e.g. #_ DigSig noshow _#

NOTE : the DigSig parameter *must* be followed by at least one other piece of text so that the regular expression can find it.  Anything other that the parameters shown above are ignored, so it is fine to just put something simple like '1'.  e.g.  #_ DigSig 1 _#

NOTE : Set up the other signature details in the pdfMachine options.
 

 

Files Attached / Embedded within the PDF

The following parameter causes pdfMachine to attach file(s) to the resultant PDF file.  The attached files can be seen in the attached files list in Acrobat Reader 6 and 7.

Parameter Description
embed Argument:  Path of the file to be embedded.
 
e.g.
  #_ embed C:\afile.pdf _#
  #_ embed C:\somefile.pdf _#

Call embed multiple times to embed multiple files. See example.

 

 

Insert Image

The following parameter causes pdfMachine to insert images into the resultant PDF file.

Parameter Description
InsertImage Arguments: width height path

e.g. #_ InsertImage 100 100 C:\somefile.jpg _#
 
width optionally specify the width in points for the picture in the PDF file.
height optionally specify the height in points for the picture in the PDF file.
path path to the image file.

Note: 1 point = 1/72th inch

InsertImage can be called more than once per page.

 

Split Document

Parameter Description
SplitPDF Argument: dummy argument to help regular expression parsing

e.g.  #_ SplitPDF 1 _# 

Note the SplitPDF parameter must be followed by some other text, which is '1' in this case.


Splits document at the end of the current page.  This should be used with extreme caution, as it may result in multiple emails being sent for a single print job. 
Please be sure you do adequate testing to ensure the emails are as you wish.
 

see example

Make sure that there is no more that one SplitPDF command on a single page.

This can be useful for integrating with a legacy application that creates one big print job with each customer statement on a new page. 

e.g. An accounting application may print out a number customer invoices, one after the other in one big print job.  Normally this would generated 1 large PDF.  However, using a combination of "SplitPDF" and "email" parameters each customer would be emailed a unique invoice belonging to them.

bookmark

Parameter Description
bm Argument: bookmark name\sub bookmark name

A back slash separated list of heading names, forming a table of contents or bookmark hierarchy.

Bookmarks provide a table of contents and usually represent the chapters and sections in a document.

Bookmarks appear in the navigation pane of adobe reader.   When a bookmark is clicked, the reader will be presented with the section where the "bm" command was placed.


e.g
 #_ bm This is a top level bookmark _# 
 #_ bm This is a top level bookmark\sub section 1 _# 
 #_ bm This is a top level bookmark\sub section 2\more news _#   

Produces PDF with a bookmarks window in Adobe Reader:


 
   

Print

Parameter Description
print Argument: printer name

Used to print to a secondary printer.

This could be useful if a hardcopy is desired as well as the PDF.
If the word "default" is used for the printer name the default printer is used.

e.g 1 - Print to a specific printer name

 #_ print HP Office Jet v49 _# 

e.g 2 - Print to the default printer

 #_ print default _#
