Access document attributes?

Recently someone posted a query on the ColdFusion 8 Forums asking about cfpdf and accessing document attributes.

=========================

I was wondering if there was a way you could use CFPDF to access document attributes and extract embeded images and text from a PDF? Would there be a way for use to access text blocks created by the user (along with the x:y coordinates)?

 

For example, A LOT of sites convert the PDF to a JPEG and create area maps to simulate a zoom effect. Just looking for a way to deconstruct the PDF using the new CFPDF tag...
=========================

 

Most of these things requested are possible using cfpdf tag.

 

You can extract document attributes like metadata using cfpdf action="getinfo"

 

Extracting Text using cfpdf tag action=processddx. (code for extracting text from pdf follows below)..

 

You can't extract images from pdf. You can create JPEG images from pdf pages using action="thumbnail" and you can also specify o/p image format in this tag.

DDX File:

   </DocumentText>
</DDX>

 

CFM File:

 

<cfset ddxfile = "<Webroot>\ddx-textExtract\doc_text.ddx">
<cfset sourcefile1 = "<Webroot>\ddx-textExtract\<Any pdf having text>">
<cfset destinationfile = "<Webroot>\ddx-textExtract\ddx_result_doc_text.xml">

 

<cfset inputStruct=StructNew()>
<cfset inputStruct.Doc1="#sourcefile1#">

 

<cfset outputStruct=StructNew()>
<cfset outputStruct.Out1="#destinationfile#">

 

<cfpdf action="processddx" ddxfile="#ddxfile#" inputfiles="#inputStruct#" outputfiles="#outputStruct#" name="ddxVar">

 

<cfoutput>#ddxVar.Out1#</cfoutput>
