Use the cfpdf tag to read an existing PDF, write meta-data to it, merge PDFs together, delete pages, create thumbnails of the pages, extract text and images, add or remove watermarks, electronically sign or unsign documents, sanitize and redact PDF contents for better security, and safeguard the PDFs with a password.

Description

Manipulates existing PDF documents. The following list describes some of the tasks you can perform with the cfpdf tag:

  • Merge several PDF documents into one PDF document.
  • Delete pages from a PDF document.
  • Merge pages from one or more PDF documents and generate a new PDF document.
  • Linearize PDF documents for faster web display.
  • Remove interactivity from forms created in Acrobat to generate flat PDF documents.
  • Encrypt and add password protection to PDF documents.
  • Generate thumbnail images from PDF documents or pages.
  • Add or remove watermarks from PDF documents or pages.
  • Retrieve information associated with a PDF document, such as the software used to generate the file or the author, and set information for a PDF document, such as the title, author and keywords.
  • Create PDF portfolios
  • Add and remove header/footer from PDF documents
  • Optimize PDF documents

validatesignature

New in ColdFusion 11–Validates all the signatures
in the document. The name attribute will then store
the resultant struct of this operation. The name attribute will contain 2 elements:

    • A Boolean field that indicates whether all the signatures have been deemed
      valid or not. 
    • An array list consisting of the names of all the signatures that were invalid.
      If all the signatures are valid, the array list will be empty.

readsignaturefields

New in ColdFusion 11–Reads all the signature fields and returns a query object in the variable
indicated by the attribute name. This query object will have 4 columns:

    • Name–A fully qualified name of the signature field
    • Certifiable--Indicates if this field can contain an author signature or not
    • Signable–Indicates whether this field can be signed or not
    • Is signed–Indicates whether this field is already signed or not

New in ColdFusion 2016:

Required

Specifies the algorithm for image downsampling. The values are bilinear, bicubic, and nearest_neighbour

ascending

merge

Optional

Order in which the PDF files are sorted:

yes: Files are sorted in ascending order

no: Files are sorted in descending order
Applicable only when you specify the directory attribute.

author

sign

Optional

Business transactions, including financial, legal, and other 
regulated transactions,
require high assurance when signing documents.  When documents are distributed electronically, it is important that  recipients can:

Verify document authenticity – confirm the identity of person who signed the document

Verify document integrity –
confirm that the document has
not been altered in transit

Author-based signatures provide both of these security services.

If attribute is not mentioned
then it is treated as author=false

bottomMargin

Required for
the write action
Optional for all other actions

Pathname of the modified PDF document. If the destination file exists, set the overwrite attribute to yes.
If the destination file does not exist, ColdFusion creates the file, if the parent directory exists.
You can specify the destination attribute or the name attribute, but not both.
For the thumbnail action, the destination is the directory path where the images are written. If you specify a relative pathname to the destination directory, the destination directory is relative to the template directory. If you do not specify a destination directory, ColdFusion creates a directory called thumbnails in the directory in the template directory.
For the optimize action, destination is the path where the PDF document which needs to be optimized is located. For extracttext and extractimage , destination is the path of the PDF document from which the text or image needs to be extracted.
For addheader , addfooter , removeheader footer, destination is the path of the PDF document where you need to add a header or footer, or remove the header and footer.
For transform, destination specifies the directory path of the PDF document where you need to perform page level transformations.

directory

merge

Optional

Directory of the PDF documents to merge. Specify either the directory attribute or the source attribute. If you specify the directory attribute, ColdFusion orders the documents by filename in descending order, by default. To change the order of the files, use the order attribute.

encodeall

write

Optional

Encode streams that are not encoded to optimize page content

encrypt

protect

Optional

Encryption type for the PDF output file. In ColdFusion 2016, there is support for two new encryption algorithms, AES_256R6 and AES_256R5.

  • RC4_40
  • RC4_128
  • RC4_128M
  • AES_128
  • AES_256R6
  • AES_256R5
  • None

Archiving a signed PDF created using ColdFusion behaves abnormally when opened using Adobe Acrobat. To fix the document for archiving enable the "Changing the Document" permission under the Security options of Acrobat.

Usage

You use the cfpdf tag to manipulate and assemble existing PDF documents. Although the cfpdf tag provides much of the functionality available in Acrobat, you cannot use this tag to generate a PDF document from another file format. To create PDF output from HTML and CFML content, use the cfdocument tag.
You cannot embed a cfpdf tag within a cfdocument tag or embed a cfdocument tag within a cfdpdf tag; however, you can write the output of a cfdocument tag to a variable and pass the variable to the cfpdf tag. The following example shows how to use the cfdocument tag to create a cover page and add it to a merged PDF document:

<!--- Use the cfdocument tag to create a cover page and write the output to a variable called 
cfdoc. ---> 
<cfdocument format="PDF" name="cfdoc"> 
<html> 
<body> 
<h1>Here is a cover page</h1> 
</body> 
</html> 
</cfdocument> 

<!--- Use the cfpdf tag and cfpdfparam tags to merge individual PDF documents into a new PDF document called new.pdf. Notice that the cfdoc variable created by using the cfdocument tag is the source value of the first cfpdfparam tag. ---> 
<cfpdf action="merge" destination="/samtemp/pdfs/new.pdf" overwrite="yes"> 
<cfpdfparam source="cfdoc"> 
<cfpdfparam source="/samtemp/pdfs/pdf2.pdf"> 
<cfpdfparam source="/samtemp/pdfs/pdf1.pdf"> 
</cfpdf>

You can use the cfpdf tag to assemble interactive PDF form files into a single PDF document and flatten forms created in Acrobat (by using the flatten attribute with the write action); however, to process PDF form data, use the cfpdfform and related tags. You cannot use the cfpdf tag to flatten forms created in Adobe LiveCycle Designer ES.

Reading and writing PDF files

The cfpdf tag provides several options for reading and writing PDF files. You can specify a PDF variable or a PDF file as the source, and you can write the output to a variable or to a file (but not both). The following table explains the read and write operations:

Task

Attributes

Example

Overwrite a source PDF file

Specify the PDF file pathname as the source and do not specify a destination.

<cfpdf action="addWatermark" source="myPDF.pdf" image="myImage.jpg">

Write a PDF document in memory to a file

Specify the PDF variable as the source and a PDF file pathname for the destination.

<cfpdf action="addWatermark" source="myPDF" image="myImage.jpg" destination="outputFile.pdf">

Write a PDF document to a new file

Specify a PDF file pathname as the source and a different PDF file pathname as the destination.

<cfpdf action="addWatermark" source="sourceFile.pdf" image="myImage.jpg" destination="outputFile.pdf">

Write a PDF file to a PDF variable

Specify the PDF file pathname as the source and a PDF variable name.

<cfpdf action="addWatermark" source="sourceFile.pdf" image="myImage.jpg" name="myPDF">

Overwrite a PDF document in memory

Specify the PDF variable name as the source and do not specify a destination.

<cfpdf action="addWatermark" source="myPDF" image="myImage.jpg">

Working with PDF files in memory

ColdFusion gives you the option to write a PDF file to a variable by using the name attribute, which is useful if you want to perform multiple operations on a document before writing it to a file. However, this is practical for small files only because of memory requirements. If you are working with large PDF documents, write the PDF documents to files.ColdFusion recommends that you do not specify the name attribute when you specify a variable as the source because it creates a copy, which increases processing. In most cases, this is unnecessary because you can reuse variables even after you write them to files.

Note:

When you use PDF variables within a try/catch block and ColdFusion generates an error, the variables are unusable after the error is generated.

Printing PDF documents

Use the cfprint tag to print PDF documents. Markups, such as sticky notes, comments, and editorial revisions, are not printed with the document.

  • addWatermark action Use the addwatermarkaction to add a watermark to specified pages in a PDF document. You can add a watermark in one of the following ways:
    • Use the first page of another PDF document as a watermark. ColdFusion overlays the copyfrom page on the source document, without enlarging the image.
    • Specify an image file to use as a watermark.
    • Specify an image in memory by using an image variable.
      The following code shows how to use the first page of a PDF document as a watermark:

<cfpdf action="addWatermark" source="c:\myBook.pdf" copyFrom="e:\yourBook.pdf" 
destination="ourBook.pdf" overwrite="yes">

By default, ColdFusion applies the watermark to all of the pages in the output file, with the watermark image centered on the page. The following code applies a JPEG image as a watermark to the first page of the output file:

<cfpdf action="addWatermark" source="Book.pdf" 
image="../cfdocs/images/artgallery/paul01.jpg" destination="newBook.pdf" pages="1" 
overwrite="yes">

To specify a ColdFusion image as a watermark, use the cfimage tag or Image functions. The addwatermark action also supports RGB and ARGB images, especially the images added using the cfimagetag and related functions. The following example converts an image to grayscale and applies it as a watermark to a PDF file:

<!--- Use the ImageNew function to create a ColdFusion image from a JPEG file. ---> 
<cfset myImage=ImageNew("../cfdocs/images/artgallery/jeff05.jpg")>

<!--- Use the ImageGrayscale function to convert the image to grayscale in memory. ---> 
<cfset ImageGrayscale(myImage)> 

<!--- Specify the image variable to apply the grayscale image as a watermark in the Book.pdf file. Because the source and destination are the same and the overwrite attribute is set to yes, ColdFusion overwrites the source file. ---> 
<cfpdf action="addWatermark" source="Book.pdf" destination="Book.pdf" overwrite="yes" image="#myImage#">

For more information on ColdFusion images, see Creating and Manipulating ColdFusion Images in the Developing ColdFusion Applications.

  • addfooterUse this action to add a footer in a PDF document. Specify the source where the PDF document is located and the destination where the new PDF document with the footer is saved, as shown in the following code snippet:

<cfpdf action = "addfooter" 
source = "../myBook.pdf" 
destination = "../myBookwithfooter.pdf" 
image = "adobelogo.JPG" // Use this attribute to add an image in the 
footer 
align = "right"> // By default, the alignemnt is center

You can also specify an image or text that you have to insert in the footer along with various other attributes such as align, bottommargin, leftmargin, numberformat, and opacity.

  • addheaderUse this action to add header in a PDF document. Specify the source and destination for the PDF document and specify the text or image that you want to insert in the header, as shown in the following code:

<cfpdf action = "addheader" 
source = "../myBook.pdf" 
destination = "../myBookwithheader.pdf" 
text = "Adobe" 
align = "left">
  • deletePages action Use the deletePagesaction to remove pages from a specified PDF document. You can specify a single page, a page range, or a comma-separated list of pages, as the following code shows:
<cfpdf action="deletePages" source="c:\myBook.pdf" pages="1,16-32,89,100-147" 
destination="myLittleBook.pdf">
  • extracttext Use the extracttextaction to extract all words from the specified page numbers in the PDF document, as shown in the following code snippet:
<cfpdf action = "extracttext" source = "../myBook.pdf" pages = "5-20, 29, 80" destination = "../adobe/textdoc.txt"
  • extractimage Use the extractimage action to extract all images from the specified page number in a PDF document, as shown in the following code snippet:
<cfpdf action = "extractimage" source = "../myBook.pdf" pages = "1-200" destination = "..\mybookimages" imageprefix = "mybook">

The images are extracted and saved in the directory that you specify in the destination attribute. You can specify a prefix for the images (imageprefix) being extracted, otherwise the system prefixes the i    

  • on to extract information associated with the PDF document, such as the author, title, and creation date. You specify the name of the structure variable that contains the relevant data associated with the file, as the following code shows:

<cfpdf action="getInfo" source="myBook.pdf" name="PDFInfo"> 
<p><cfoutput>#PDFInfo.title#</cfoutput></p> 
<p><cfoutput>#PDFInfo.author#</cfoutput></p> 
<p><cfoutput>#PDFInfo.keywords#</cfoutput></p> 
<p><cfoutput>#PDFInfo.created#</cfoutput></p>

For a complete list of information elements, use the cfdumptag, as the following code shows:

<cfdump var="#PDFInfo#">
Note:

To view the permissions for a PDF document that is password-protected, specify the user password, not the owner password. If you specify the owner password, all permissions are set to Allowed.

Reducing quality of PDF document

The optimize action is used to downsample images and discard unused objects in a PDF document.

  • optimize To downsample images in a PDF document, the algos attribute is used with values bilinear, bicubic, and nearest_neighbour. The following code snippet generates a PDF after image downsampling:

<cfpdf action = "optimize" algo = "bicubic" source "..\myBook.pdf" name = #mybook#>

You can also discard unused objects such as comments, JavaScripts, attachments, bookmarks, and metadata from your PDF document using the following attributes with optimize action:

<cfpdf action = "optimize" 
noJavaScripts 
noThumbnails 
noBookmarks 
noComments 
noMetadata 
noFileAttachments 
noLinks 
nofonts>

Transforming pages in a PDF document

You can scale a page, specify the position, and rotation values for pages in a PDF document.

  • transform The transform action has four attributes that define the size (hscale, vscale), position(position), and rotation (rotation) of a page. The following code snippet shows the usage:

<cfpdf action = "transform" 
required 
source = "..\myBook.pdf" 
optional 
destination = "..\new\myBook.pdf"> 
hscale = ".5" 
vscale = ".15" 
position = "8, 10" 
rotation = "180">

The value for rotation must be in steps (0, 90, 180, 270). If you specify any other value, the system generates an error.

  • merge action Use the merge action to assemble PDF documents or pages from PDF source files into one output file. The following code shows how to merge all the PDF files in a directory:
<cfpdf action="merge" directory="c:\myPDFfiles" destination="oneBigFile.pdf" 
overwrite="yes">

By default, ColdFusion adds the files in descending order by timestamp. The following code merges the source files in ascending order by filename:

<cfpdf action="merge" directory="c:\book" order="name" ascending="yes" 
destination="c:\book\output1.pdf" overwrite="yes">

This is useful if the source files have logical names, such as Chap0.pdf, Chap1.pdf, Chap2.pdf, and so on.By default, ColdFusion continues the merge process even if it encounters a file in the specified directory that is not a valid PDF document. To stop the merge process if the directory contains files other than valid PDF documents, set the stopOnError attribute to yes:

<cfpdf action="merge" directory="c:\bookfiles" destination="book.pdf" overwrite="yes" 
order="name" ascending="yes" keepBookmark="yes" stopOnError="yes">

To create a PDF file from specific pages in a document, use the source attribute with the pagesattribute. The following code creates a file from pages 1-5 of the source document:

<cfpdf action="merge" source="myBigBook.pdf" pages="1-5" destination="myShortBook.pdf" 
overwrite="yes">

To merge several files into one document, specify the absolute pathnames of the files in a comma-separated list, as the following code shows:

<cfpdf action="merge" source="c:\PDFdocs\myBook\Chap1.pdf, 
c:\PDFdocs\myBook\Chap2.pdf,c:\PDFdocs\myBook\Chap3,pdf" destination="myBook.pdf" 
package = "true" overwrite="yes">

You can now create PDF packages using the package = "true" attribute with the merge action. For more control over the order of files, to assemble files in different locations, and to extract pages from multiple PDF files, use the cfpdfparam tag with the merge action. For more information on merging PDF files, see Assembling PDF Documents in the Developing ColdFusion Applications.
If cfpdf action="merge" and package="yes", all file formats can be used as source. The following sample code has ZIP and JPEG file formats as source:

<cfpdf action="merge" package="yes" destination="./myBook/adobetest.pdf" overwrite="yes"> 
<cfpdfparam source="./inputFiles/c.zip" > 
<cfpdfparam source="./inputFiles/d.jpg" > 
</cfpdf>
  • processddx action Use the proccessddx action to assemble PDF files by processing Document Description XML (DDX) instructions. DDX is a declarative markup language used by Adobe LiveCycle Assembler. You can use DDX instructions to perform advanced tasks, such as adding table of contents pages, headers and footers, automatic page numbers, and text-string watermarks to PDF documents.ColdFusion provides a subset of LiveCycle Assembler functionality. To determine whether you can perform your tasks in ColdFusion or whether you have to purchase LiveCycle Assembler, see the tables in the following sections.
    For complete DDX syntax, see the Adobe LiveCycle Assembler Document Description XML Reference.

Simple DDX instructions

You can create DDX instructions in any text editor and save the file with a DDX extension. The following example shows the DDX instructions for merging several documents and generating a table of contents with bookmarks from the source PDF documents:

<?xml version="1.0" encoding="UTF-8"?> 
<DDX xmlns="http://ns.adobe.com/DDX/1.0/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://ns.adobe.com/DDX/1.0/ coldfusion_ddx.xsd"> 
<PDF result="Out1"> 
<PDF source="Title"/> 
<TableOfContents/> 
<PDF source="Doc1"/> 
<PDF source="Doc2"/> 
<PDF source="Doc3"/> 
</PDF> 
</DDX>

Processing DDX instructions in ColdFusion

The following code processes the DDX instructions in ColdFusion:

<!--- The following code verifies that the DDX file exists and the DDX instructions are valid. ---> 
<cfif IsDDX("Book.ddx")> 

<!--- The following code maps the PDF source files to the PDF source variables in the 
DDX file. ---> 
<cfset inputStruct=StructNew()> 
<cfset inputStruct.Title="Title.pdf"> 
<cfset inputStruct.Doc1="Chap1.pdf"> 
<cfset inputStruct.Doc2="Chap2.pdf"> 
<cfset inputStruct.Doc3="Chap3.pdf"> 

<!--- The following code maps the PDF output file to the PDF result variable in the DDX 
file. ---> 
<cfset outputStruct=StructNew()> 
<cfset outputStruct.Out1="output.pdf"> 

<!--- The following code process the DDX instructions in the Book.ddx file to generate 
a merged document. ---> 
<cfpdf action="processddx" ddxfile="Book.ddx" inputfiles="#inputStruct#" 
outputfiles="#outputStruct#" name="ddxVar"> 
<cfelse> 
<p>The DDX instructions are not valid.</p> 
</cfif> 

<!--- The following code displays a success or failure message. ---> 
<cfoutput>#ddxVar.Out1#</cfoutput>

The name attribute defines a variable that you use to determine the success or failure of the process. Use the cfoutput tag to display the success or failure message, as the previous example shows, or use the cfdump tag to display a structure:

<cfdump var="#ddxVar#">

This code returns the following information for each output file in the structure:

  • "Successful", if the file is assembled successfully.
  • "Reason for failure", if the file is not assembled successfully and the reason for failure is known.
  • "Failure", if the file is not assembled successfully and the reason for failure is not known.
    Use the IsDDX function to determine whether a DDX file or set of instructions is valid.
    For detailed examples, see Assembling PDF Documents in the Developing ColdFusion Applications.
  • protect action Use the protect action to password-protect PDF output files, set permissions, and encrypt PDF output files. When you use the protect action, set a newUserPassword or a newOwnerPassword. (You can set both, as long as the passwords differ.) When you assign a user password to a document, all users must use this password to open the PDF document. The following code adds a user password to a PDF document:

<cfpdf action="protect" source="Finances.pdf" destination="myFinances.pdf" 
newUserPassword="keepOut">

To set the permissions on the output file, set the newOwnerPassword. A user who enters the owner password when accessing the PDF file is considered the owner of file. The following example shows how to set a new owner password:

<cfpdf action="protect" encrypt="AES_128"source="Book.pdf" destination="MysteryBook.pdf" 
overwrite="yes" newOwnerPassword="pssst" permissions="AllowDegradedPrinting">

Because the permissions are set to AllowDegradedPrinting in this example, ColdFusion lets users print the document at 150 DPI, but prohibits all other actions. If a user tries to delete the file, for example, ColdFusion generates an error message indicates that the password was entered incorrectly or the permissions do not allow the action to be performed.ColdFusion does not retain permissions: if you add a newUserPassword attribute, you also must set the permission explicitly.
To work with myVar, you specify newownerpw as the password.

PDF document passwords

A PDF document can have two kinds of passwords: a user password and an owner password. The following table describes the two types of ColdFusion passwords and their equivalents in Acrobat:

ColdFusion password

Acrobat equivalent

Description

User password

Document Open password, user password

Anyone who tries to open the PDF document must enter the password that you specify. A user password does not allow a user to change restricted features in the PDF document.

Owner password

Permissions password, master password

Lets the person who enters the password restrict access to features in a PDF document.

When you protect a PDF, your password changes to the one you provide. ColdFusion updates the variable's saved password to the one you provide. However, if you provide both passwords, ColdFusion uses the owner password. The following protects a PDF:

<cfpdf action="protect" source="myVar" password="oldpassword" 
permissions="none" newuserpassword="newuserpw" 
newownerpassword="newownerpw">

To get all the properties of the PDF, you do the following:

<cfpdf action="info" source="myVar" name="info">

To get only the properties allowed for the user, you do the following:

<cfpdf action="info" source="myVar" password=" newuserpw" name="info">

Permissions for PDF documents

The following table lists the permissions an owner can set for PDF documents:

Permissions

Description

All

There are no restrictions on the PDF document.

AllowAssembly

Users can add the PDF document to a merged document.

AllowCopy

Users can copy text, images, and other file content. This setting is required to generate thumbnail images with the thumbnail action.

AllowDegradedPrinting

Users can print the document at low-resolution (150 DPI).

AllowFillIn

Users can enter data into PDF form fields. Users can sign PDF forms electronically.

AllowModifyAnnotations

Users can add or change comments in the PDF document.

AllowModifyContents

Users can change the file content. Users can add the PDF document to a merged document.

AllowPrinting

Users can print the document at high-resolution (print-production quality). This setting is required for use with the cfprint tag.

AllowScreenReaders

Users can extract content from the PDF document.

AllowSecure

Users can sign the PDF document (with an electronic signature).

None

Users can view the document only.

Encryption for PDF documents

The encrypt attribute sets the type of encryption used for opening a password-protected document. By default, ColdFusion uses the RC4 128-bit encryption algorithm to encrypt PDF files. To change the encryption algorithm, use the encrypt attribute with the protect action. The following code encrypts the PDF output file with the AES algorithm:

<cfpdf action="protect" encrypt="AES_128" source="Book.pdf" destination="MysteryBook.pdf" 
overwrite="yes" newOwnerPassword="pssst" permissions="AllowDegradedPrinting">

ColdFusion supports the following encryption algorithms:

Encryption algorithm

Compatibility

Description

AES_128

Adobe Acrobat 7.0 and later

Advanced Encryption Standard (AES) specifies the Rijndael algorithm, a symmetric block cipher that can process data blocks of 128 bits. This is the highest encryption level.
This encryption algorithm lets users do the following:

  • Encrypt all document contents.
  • Encrypt all document contents except for the metadata.
  • Encrypt only the file attachments.

RC4_128M

Adobe Acrobat 6.0 and later

RC4 specifies the RSA Security software stream cipher for algorithms such as Secure Sockets Layer (SSL), to protect Internet traffic, and WEP, to secure wireless networks.
This encryption algorithm lets users do the following:

  • Encrypt all document contents.
  • Encrypt all document contents except for the metadata.

RC4_128

Adobe Acrobat 5.0 and later

RC4 128-bit encryption. This encryption algorithm lets users encrypt the document contents, but not the document metadata.

RC4_40

Adobe Acrobat 3.0 and later

RC4 40-bit encryption. This is the lowest encryption level.

None

-

The document is not encrypted.

Note:

Document metadata is used in Internet searches. If the metadata is encrypted, search engines cannot search the PDF document. Users running an earlier version of Acrobat cannot open a PDF document with a higher encryption setting. For example, if you specify AES 128 encryption, a user cannot open the document in Acrobat 6.0 or earlier.

  • read action Use the read action to read the source PDF document into the namevariable, as the following code shows:
<cfif IsPDFFile("Book.pdf")> 
<cfpdf action="read" source="Book.pdf" name="myBook"> 
... 
</cfif>
  • removeWatermark action Use the removewatermarkaction to remove a watermark from a PDF document or specified pages in a document. The following example removes a watermark from the first page of a PDF document and writes the output to a new file:
<cfpdf action="removeWatermark" source="Book.pdf" pages="1" destination="newBook.pdf" overwrite="yes">
  • removeheaderfooter action Use this action to remove the header and footer from a PDF document or from specified pages in a document. The following example removes the header and footer from the entire document:
<cfpdf action = "removeheaderfooter" source="..\mybook.pdf" destination = "new.pdf">
  • setInfo action Use the setinfo action to specify information associated with a PDF document to be saved with it. Create a structure that contains the relevant information. Use the info attribute of the cfpdf tag to refer to the structure. The following code shows the elements that you can modify by using the setInfoaction:
<cfset PDFinfo=StructNew()> 
<cfset PDFinfo.Title="Make Way for Ducklings"> 
<cfset PDFinfo.Author="Donald Duck"> 
<cfset PDFinfo.Keywords="Huey,Dewy,Louie"> 
<cfset PDFinfo.Subject="Ducks"> 
<cfpdf action="setInfo" source="chap1.pdf" info="#PDFinfo#" destination="meta1.pdf" overwrite="yes">
  • thumbnail action Use the thumbnail action to generate thumbnail images from the source PDF document.
    If you do not specify a destination directory for the thumbnail files, ColdFusion creates a directory for the thumbnails in the directory where the CFM page is located. If you specify a filename as the source, the thumbnail directory name is a concatenation of the name of the source file and _thumbnails. For example, the following code generates a thumbnail image for each page in myBook.pdf and stores them in a directory called myBook_thumbnails:
<cfpdf action="thumbnail" source="myBook.pdf">

If the CFM page is located in the directory c:\myProject\genThumbnails.cfm, the pathname for the thumbnails directory is c:\myProject\myBook_thumbnails.By default, ColdFusion generates thumbnail files in JPEG format and the images are scaled to 25% of the original.
You can specify individual pages within the source document to generate thumbnails. Also, you can change the size of the thumbnail; the resolution, the output format (JPEG, PNG, or TIFF); and the prefix used for the thumbnail filenames. The following code generates a low-resolution thumbnail from the first page of the source document that is scaled at 50% of the original size:

<cfpdf action="thumbnail" source="myBook.pdf" pages="1" destination="c:\myBook\images" 
imagePrefix="Cover" format="png" scale="50" resolution="low">

The full output file pathname is as follows:

c:\myBook\images\Cover_page_1.png

Note:

To generate thumbnail images, the permissions of the source document must include AllowCopy. For more information, see Permissions for PDF documents in cfpdf.

With ColdFusion 9, the following new attributes were introduced for the thumbnail action:

  • hires: You can set this attribute to true to extract high-resolution images from the page. If a document contains high-resolution images and you want to retain the resolution of the images, then this attribute is useful.
    For example:

<cfpdf action="thumbnail" source="./WORK/myBook.pdf" destination="./WORK/Testing_CFPDF" overwrite="true" hires="yes">
  • overridepage: If you set this attribute to true, the thumbnail generated does not adhere to the PDF page size, but to the image size that is present in that page. If the image is not present, the size is set to the maximum size of the page.
  • compresstiffs: Use this attribute to compress the size of the thumbnail images. As the name of the attribute suggests, it is only valid for the TIFF format. Following is an example:

<cfpdf action="thumbnail" source="C:\WORK\myBook.pdf" destination="C:\WORK\Testing_CFPDF" overwrite="true" hires="yes" format="tiff" compresstiffs="yes">
  • maxscale : Use this attribute to specify an integer value for the maximum scale of the thumbnail images.
  • maxlength: Use this attribute to specify an integer value of the maximum length of the thumbnail images.
  • maxbreadth: Use this attribute to specify an integer value of the maximum width of the thumbnail.
    The following example illustrates the use of maxscale, maxlength, and maxbreadth:

Note: Typically, the value of the scale attribute is set to 100 when using the maxscale attribute.

  • write action Use the writeaction to write the source PDF document, or the PDF document stored in memory as a variable, to a file. The following code converts a PDF file stored in memory to a different PDF version and writes the output to a new file:
<cfpdf action="read" source="Book.pdf" name="myBook"> 
<cfpdf action="write" source="myBook" destination="myBook1.pdf" 
version="1.4">

You can now use either name or destination attributes with the write action. The name attribute takes the value as the PDF document variable. For example, you can write the preceding code snippet as:

<cfpdf action="read" source="Book.pdf" name="myBook"> 
<cfpdf action="write" source="myBook" name=#myBook# 
version="1.4">

The new encodeall attribute encodes all the unencoded streams in the source. However, it does not discriminate between dumb encodings like LZW and encodings like flate, so only unencoded streams get flateencoded.

Note:

You can now register thumbnail fonts using the font management screen.

PDF versions

Change the PDF version so that users running an older version of Acrobat or Adobe Reader can open the file. The following table shows the compatibility between the PDF version and the corresponding Acrobat and Adobe Reader versions:

PDF version

Compatibility

1.1

Acrobat and Adobe Reader 2

1.2

Acrobat and Adobe Reader 3

1.3

Acrobat and Adobe Reader 4

1.4

Acrobat and Adobe Reader 5

1.5

Acrobat and Adobe Reader 6

1.6

Acrobat and Adobe Reader 7

To linearize PDF documents for faster web display, set the saveOption attribute to linear, as the following code shows:

<cfpdf action="write" source="myBook" destination="myBook1.pdf" saveOption="linear" 
overwrite="yes">

Do not use the linear save option if you have to maintain interactivity in PDF forms or if the PDF document is enabled for electronic signatures. To allow for electronic signatures, set the saveOption attribute to incremental, as the following code shows:

<cfpdf action="write" source="myDraft" destination="mySignedDoc.pdf" 
saveOption="incremental" overwrite="yes">

Use the flatten attribute to flatten forms created in Acrobat:

<cfpdf action="write" source="myAcrobatForm.pdf" 
destination="myFlatForm.pdf" flatten="yes" overwrite="yes">
Note:

ColdFusion does not support flattening forms created in Adobe LiveCycle. For more information about forms created in LiveCycle and Acrobat, see Manipulating PDF Forms in ColdFusion in the Developing ColdFusion Applications.

Example

The following example generates thumbnail images from pages in a PDF document and links the thumbnail images to the pages in the PDF document:

<h3>PDF Thumbnail Demo</h3> 

<!--- Create a variable for the name of the PDF document. ---> 
<cfset mypdf="myBook"> 
<cfset thisPath=ExpandPath(".")> 
<!--- Use the getInfo action to retrieve the total page count for the 
PDF document. ---> 
<cfpdf action="getInfo" source="#mypdf#.pdf" name="PDFInfo"> 
<cfset pageCount="#PDFInfo.TotalPages#"> 

<!--- Generate a thumbnail image for each page in the PDF source document, 
create a directory (if it doesn't already exist) in the web root that is 
a concatenation of the PDF source name and the word "thumbnails", and 
save the thumbnail images in that directory. ---> 
<cfpdf action="thumbnail" source="#mypdf#.pdf" overwrite="yes" 
destination="#mypdf#_thumbnails" scale=60> 

<!--- Loop through the images in the thumbnail directory and generate a link 
from each image to the corresponding page in the PDF document. ---> 
<cfloop index="LoopCount" from ="1" to="#pageCount#" step="1"> 
<cfoutput> 
<!--- Click the thumbnail image to navigate to the page in the PDF 
document. ---> 
<a href="#mypdf#.pdf##page=#LoopCount#" target="_blank"> 
<img src="#mypdf#_thumbnails/#mypdf#_page_#LoopCount#.jpg"></a> 
</cfoutput> 
</cfloop>

Archiving PDF documents 

Introduced in ColdFusion 11: Use the action type=”archive” to archive the PDF files based on the ISO's PDF/A standards.PDF/A  is one set of standards among a  suite of PDF-based standards managed by the International Organization for Standardization (ISO). It was developed to enable the long-term preservation of electronic documents and provides specifications for the creation, viewing, and printing of PDF documents, with the intent of preserving final documents of record as self-contained documents.  The standard does not define an archiving strategy or the goals of an archiving system. Rather, it identifies a "profile" for a PDF file that makes it possible to reproduce the visual appearance of the document the exact same way in the future. This profile specifies what must be included in the file, while prohibiting features that are not suitable for long-term archiving.

<!---- Create an archived pdf from source pdf ---à
<cftry>
<cfpdf action="archive" source="#sourcefilename#" destination="#destinationfilename#" overwrite="true" />
<cfcatch>
<cfoutput>#cfcatch.detail#</cfoutput><br><br>
</cfcatch>
</cftry>

Digitally signing the documents

Introduced in ColdFusion 11: Use the action =”sign”,”unsign”,”validatesignature”,"readsignaturefields" for creating a digital signature, removing the digital signature, validating the signatures of a document, and for reading the signature fields respectively.

  • For action =”sign”, the following attributes are available:
    • keystore attribute(Required):The location of the keystore file. For example:C:\OpenSSL\bin\keystore.jks.
    • keystorepassword attribute (Required): The password for the keystore.
    • keyalias attribute (Optional):Alias of the key with which the certificate and private key are stored in the keystore. If it is not specified, the first entry in the keystore is chosen as the alias.
    • keypassword attribute (Optional):Password for your private key. If not specified, the keystorepassword is used.
  • author attribute (Optional): If true, generates an authored signature. If false, then generate an ordinary signature.
<!---- Sign a specific pdf by creating a signature field and signing it with authoured signature -->
<cfpdf action="sign"
source="#inputfilepath##inputfilename#"
destination="#signedfilepath##signedfilename#"
keystore="#certpath#cert.pfx" keystorepassword="certpass"
overwrite="true" pages="1" height="100"
width="100" position="100,100" author="false"
/>
  • For action =”sign” and "unsign", the following attribute is available:
  • signaturefieldname attribute(Optional):Fully qualified name of the existing field on which the user wants to sign (or) the signature field which has to be unsigned.
<!---- Sign a specific signature field in a input pdf ---->
<cfpdf action="sign"
source=”#inputfilepath##inputfilename#"
destination="#signedfilepath##signedfilename#"
keystore="#certpath#cert.jks" keystorepassword="password"
overwrite="true" author="true"
signaturefieldname="sign_me"/>
  • For action =”unsign”, the following attribute is available:
  • Unsignall attribute (Optional): If true, then will unsign all signature fields in the source document.
<cfpdf action="unsign" source="../cfpdf_normalPDFSign.pdf" destination="../results/cfpdf_normalPDFSign.pdf" unsignall="true" overwrite="true">
  • For action =”validatesignature”, the following attribute is available:
  • Name attribute which will store the resultant structure of this operation. It consists of two elements. One is the boolean field which indicates whether all signatures have been deemed valid or not. The second is an array list consisting of the names of all the signatures which were invalid.
<cfpdf action="validatesignature" source="../cfpdf_normalPDFSign.pdf" name="pdfInfo">
<cfoutput>#pdfInfo.SUCCESS#</cfoutput>
  • For action =”readsignaturefields”:
  • Reads all the signature fields and returns a query object in the variable indicated by attribute name. This query object will have five columns. The five columns are:

a) Signed - fully qualified name of the signature field.

b) Authored - indicates if this field can contain an author signature or not.

c) Can_Be_Signed - whether this field can be signed.

d) Can_Be_Authored - tells if this field is already signed or not 

e) Visible - tells if the field is visible.

<!--- Read info about signature fields in a 
input pdf in a variable and dump it --->
