Splitting Pdf

I am trying to write a cold fusion program which splits up a pdf file with multiple pages into separate files for each page. In other words, let's say I have a pdf document (document.pdf) that has 100 pages, I want the program to break it up so I end up with 100 files, one for each page (document0001.pdf, document0002.pdf,document0003.pdf,document0004.pdf,document0005.pdf etc, etc.). Any help would be greatly appreciated.

Here is a rough example. I only skimmed the API so no guarantees. You can change the numbering of the file names on your own.

Hi Foresite,

I hope you are still active here.

I noticed your question, and I cannot seem to find the answer that helped you.

I am looking for ways to do exactly what you were looking back than.

Can you help out, please?

@PCR3TDDV , in software terms, 2006 is quite a number of generations ago. ColdFusion has moved on since then. From ColdFusion 8 onwards, you can use cfpdf to perform operations on a PDF file.

For example, the following function will extract each page of a given PDF document as a single PDF document:

<cffunction name="extractPDFDocAsSinlePages" output="false" returntype="void">
	<cfargument name="originalPDFDocSource" required="yes" type="string">
	<cfargument name="destinationFolder" required="yes" type="string">
	<cfargument name="totalnumberOfPagesOfOriginalPDFDoc" required="yes" type="numeric">
	
	<cfset var numberOfPages=arguments.totalnumberOfPagesOfOriginalPDFDoc>
	<cfif numberOfPages eq 1><!---Nothing to do.--->
		<cfreturn>
	</cfif>
	
	<cfset var currentPage=0>
	<cfset var pagesToDelete="">
	
	<cfloop index="currentPage" from="1" to="#numberOfPages#">	
		<cfif currentPage eq 1>
			<cfset pagesToDelete="2-#numberOfPages#">
		<cfelseif currentPage eq numberOfPages>
			<cfset pagesToDelete="1-#numberOfPages-1#">
		<cfelse>
			<cfset pagesToDelete="1-#currentPage-1#,#currentPage+1#-#numberOfPages#">
		</cfif>
		
		
		<cfpdf
	    action = "deletepages"
	    pages = "#pagesToDelete#"
	    source = "#arguments.originalPDFDocSource#"
	    overwrite = "yes"
	    destination = "#arguments.destinationFolder#\myDoc_page_#currentPage#.pdf">
	    
	</cfloop>

</cffunction>

<!--- Test Code --->
<!--- testDoc.pdf has 18 pages --->
<!--- The 18 extracted pages are stored in C:\Users\BKBK\Desktop\docs\extracted --->
<!---
<cfoutput>#extractPDFDocAsSinlePages("C:\Users\BKBK\Desktop\docs\testDoc.pdf","C:\Users\BKBK\Desktop\docs\extracted",18)#</cfoutput>
--->

This thread has an example of reading/writing a pdf. Its concatenating files
instead of splitting, but it might get you started

Thanks for your response. I had already seen that posting and struggled with the code. It works great for concatenating files but I am not a good enough programmer to use it to get to spiltting a pdf file. It works extremely fast in concatenating files and I was hoping to use similar coade to split a pdf up.
