Awesome. It does not answer the why problem, but it did offer an alternative thing for me to do. The iText worked great. I think I am going to be doing some iText learning, because the file is significantly smaller.
As you said, it's not as easy, but it works nicely.
Also, FYI - you need to fix your sample code. On line 30, it says:
ii = i + 1;
I think you need only one i. The while loop goes to infinity. 
SWEEEET!!!!
It worked! Up until I started messing with the example. lol
So I have an example from you that takes an existing PDF file and adds a watermark - works perfectly.
I have an example of creating a NEW PDF file and adding footer info to it. I was able to change the text of the footer (and the font/color to match my needs), but a couple of noob issues.
1) It wants to insert page numbers. I am guessing it is a default, because I can't find anything in the sample code adding the page numbers. I don't want the page numbers, how do I get rid of those?
2) Your example is CREATING a PDF file, and adding the footer to it. I tried to read an existing PDF and add the footer and I kept breaking it. I can't get the input and the output to jive.
It will likely take you less time to write it than to explain it, and again, if you don't want to, no worries:
I need two sample cfm files:
1) Add a footer:
Read a file: base.pdf
Add a footer "My Footer on every page" to every page of the file (no page numbers)
Output the file to: base_out.pdf
2) Add text on a specific page on a specific area:
Read a file: base.pdf
Add a text "Star Wars Rocks" at x,y coordinate 300,200 on page 2, font TimesRoman, font 10, bold
Output the file to: base_out.pdf
With this basic code, I am pretty sure I will be able to make all the iterations that I will need and will likely never bother you again.
1) It wants to insert page numbers. I am guessing it is a default, because I can't find anything in the sample code adding the page numbers.
No, it is in the code:
Local.text = variables.instance.footerText &" page ["& arguments.writer.getPageNumber() &"]";
2) Your example is CREATING a PDF file, and adding the footer to it. I tried to read an existing PDF and add the footer and I kept breaking it. I can't get the input and the output to jive.
Yes. In my rush, I forgot you wanted manipulate an existing pdf. PdfWriter's are for new documents, obviously. To add the footers, use a PdfStamper, like in the watermark example. Since you are using one already for the watermark, you could probably combine the operations in that same loop.
It will likely take you less time to write it than to explain it, and again, if you don't want to, no worries:
No, I prefer to help _you_ figure out how to do it. Otherwise, you may not understand what the code is doing or how fix/modify it in the future.
1) Add a footer:
Read a file: base.pdf
Add a footer "My Footer on every page" to every page of the file (no page numbers)
Output the file to: base_out.pdf
Use the watermark example as a base. Inside the loop, add the footer code from onPageEnd(). So the code adds a watermark AND footer to each loop. Since the footer code will not be in function, just be sure to fix the variable scopes
// do not do this in production! see memory leak article above
libpaths = [];
arrayAppend(libpaths, expandPath("/javaLoader/itext/iText-2.1.7.jar") );
loader = createObject("component", "javaLoader.JavaLoader").init(loadPaths=libpaths);
//initialize the building blocks used in footer text
textColor = loader.create("java.awt.Color").decode( "##800040" );
BaseFont = loader.create("com.lowagie.text.pdf.BaseFont");
textFont = BaseFont.createFont(BaseFont.TIMES_ROMAN , BaseFont.WINANSI, BaseFont.EMBEDDED);
textFontSize = 8;
....
p = 0;
while (p LT totalPages) {
p = p + 1;
// Prepare to place image on OVERcontent
content = pdfStamper.getOverContent( javacast("int", p) );
// begin watermark code ....
// ....
content.addImage(img);
content.saveState();
// ....
// end watermark code ....
// add the footer code here ***....
content.saveState();
content.beginText();
.... etcetera ....
}
.... rest of code ...
2) Add text on a specific page on a specific area: Read a file: base.pdf
Add a text "Star Wars Rocks" at x,y coordinate 300,200 on page 2, font TimesRoman, font 10, bold
Output the file to: base_out.pdf
With this basic code, I am pretty sure I will be able to make all the iterations that I will need and will likely never bother you again.
It is the same concept as adding a footer. You are simply adding text at a different location. Just keep in mind iText x,y coordinates start at the lower left, not top left.
rotflmao!!!
ok, Qui-Gon..... Teach a man to fish, and that sort of thing, right?
I found the Page Number footer code in the CFC, did not think to look there. I thought it would have been in the CFM. So that's done, thanks.
I added (and modified) the footer info into the Watermark example:
--WATERMARK CODE WORKS, SO I WON'T WASTE YOUR TIME POSTING THAT--
//add the javaloader dynamic proxy library (and my iText jar) to the javaloader
libpaths = [];
arrayAppend(libpaths, expandPath("/CustCFX/javaLoader/support/cfcdynamicproxy/lib/cfcdynamicproxy.jar"));
arrayAppend(libpaths, expandPath("/CustCFX/javaLoader/itext/iText-2.1.7.jar") );
//we HAVE to load the ColdFusion class path to use the dynamic proxy, as it uses ColdFusion's classes
loader = createObject("component", "CustCFX.javaLoader.JavaLoader").init(loadPaths=libpaths, loadColdFusionClassPath=true);
//initialize the building blocks used by the custom page handler
textColor = loader.create("java.awt.Color").decode( "##000000" );
BaseFont = loader.create("com.lowagie.text.pdf.BaseFont");
textFont = BaseFont.createFont(BaseFont.COURIER, BaseFont.WINANSI, BaseFont.EMBEDDED);
//intialize the page event handler component
eventHandler = createObject("component", "CustCFX.betterPdfPageEventHandler.PdfPageEventHandler").init( font=textFont, fontSize=8, textColor=textColor);
eventHandler.setFooterText( "My Cool Footer - The Force is with ME!!!");
//we can pass in an array of strings which name all the interfaces we want out dynamic proxy to implement
interfaces = ["com.lowagie.text.pdf.PdfPageEvent"];
//get a reference to the dynamic proxy class
CFCDynamicProxy = loader.create("com.compoundtheory.coldfusion.cfc.CFCDynamicProxy");
// create a proxy that we will pass to the iText writer
eventHandlerProxy = CFCDynamicProxy.createInstance(eventHandler, interfaces);
// adding content to each page
i = 0;
while (i LT totalPages) {
i = i + 1;
// Prepare to place image on OVERcontent
content = pdfStamper.getOverContent( javacast("int", i) );
// Only needed if you are changing the opacity, blending, etcetera ..
content.setGState(gState);
// Center the watermark. Note - using deprecated methods for CF8/iText 1.4 compatability
rectangle = pdfStamper.getReader().getPageSizeWithRotation( javacast("int", i) );
x = rectangle.left() + (rectangle.width() - img.plainWidth()) / 2;
y = rectangle.bottom() + (rectangle.height() - img.plainHeight()) / 2;
img.setAbsolutePosition(x, y);
content.addImage(img);
content.saveState();
content.beginText();
NOW WHAT?!?!
I tried: content.setPageEvent( eventHandlerProxy ); like in the Footer example, but that errored out. I understand what is SUPPOSED to happen here, but I am not getting the syntax. At this point, I need to apply the eventHandler to the content. But what everything I have tried has errored out.
}
One thing that I have learned is that syntax is EVERYTHING with script (that's why I love ColdFusion so much, it's much more foregiving for us non-purebread programmers.
so once I hvae initiate the beginText, what is the syntax for applying the eventHandler to content?
>I said you do not need the loadColdFusionClassPath _parameter_ , not that you do not need the javaLoader. (I even highlighted the parameter only in red too 😉
You're killing me!
As painful as that was, I am a better person for it. I was able to do the watermark, footer and then (on my own) be able to add text at a certain X,Y coordinate on a specific page. So in the end, you taught me to fish (little fish, but at least I understood it).
YOU ROCK!!!!!
Lastly, how do I go about "reporting a bug" because this really should have all been able to be handled by ColdFusion's AddWatermark feature.....
