PDFs - Watermarking & Locking Content

[Kastion2K]

Running:

• Windows Server 2003 R2
• Coldfusion 9 (Developer Edition currently)
• IIS v6.0
• MySQL

I have 2 questions regarding PDFs.

1) Will the watermarking not work in developer edition because of the Adobe watermark that is already there or am I doing it wrong?

<cfpdf action="addwatermark" source="reports/#FileName#" image="text.tiff"

    destination="c:\Inetpub\wwwroot\admin\reports\#FileName#" overwrite="yes">

2) Is there any way to lock down a PDF file? I'm writing tables of text and I want to make it so users can't select the text, is this possible?

source="reports/#FileName#" image="text.tiff"

No, it works even under the developer edition. Perhaps one of your paths is off?=. Have you tried using absolute file paths?

the text, is this possible?

Cfpdf allows you to disable certain features like copying by using action="protect". See the "permissions" section of the documentation for a complete listing. Just keep in mind these settings are not bullet proof. A determined user can find a way around such restrictions.

Thanks for the help, the link you provided answered all the questions I had concerning PDF protections.

I am still having problems with the watermarking. I used absolute pathing and still no dice. Here's the code I'm using, that I took a snippet of from a tutorial I can't find at the moment.

<cffile action="write" output="#HOLPDF#" file="c:\Inetpub\wwwroot\admin\reports\#FileName#">

<!--- Create a blank image that is 500 pixels square. --->

<cfset myImage=ImageNew("",500,500)>

<!--- Set the background color for the image to white. --->

<cfset ImageSetBackgroundColor(myImage,"white")>

<!---Clear the rectangle specified on myImage and apply the background color. --->

<cfset ImageClearRect(myImage,0,0,500,500)>

<!--- Turn on antialiasing. --->

<cfset ImageSetAntialiasing(myImage)>

<!--- Draw the text. --->

<cfset attr=StructNew()>

<cfset attr.size=50>

<cfset attr.style="bold">

<cfset attr.font="Verdana">

<cfset ImageSetDrawingColor(myImage,"blue")>

<cfset ImageDrawText(myImage,"IPSUMDIPSUM",100,250,attr)>

<!--- Write the text image to a file. --->

<cfimage action="write" source="#myImage#" destination="text.tiff" overwrite ="yes">

<!--- Use the text image as a watermark in the PDF document. --->

<cfpdf action="addwatermark" source="c:\Inetpub\wwwroot\admin\reports\#FileName#" image="c:\Inetpub\wwwroot\admin\text.tiff"

    destination="c:\Inetpub\wwwroot\admin\reports\#FileName#" overwrite="yes">

You were right, the watermarking does work. I tried it with a gigantic image and it only shows around the edges of the page. The Coldfusion Developer Edition watermark is a large white rectangle that takes almost all the page, and adding a watermark places it under the existing watermark.

EDIT:

Using foreground="yes" lets you show the watermark on top of the Adobe watermark.

The Coldfusion Developer Edition watermark is a large

white rectangle

Oh yeah, I forgot about the big white rectangle issues Any difference if you use foreground=true?

Oh, duh! I see you figured it out. Unfortunately edits are only visible via the web interface and I usually respond via email instead.
