Today's PDF entry is all about merging. ColdFusion 8 allows us to merge any number of PDFs, whether from files or directly in memory. What are some usage examples? Your site could have a standard disclaimer that you want added to the front of each PDF you create. You may have a standard credits page you want to add to the end. Whatever the need - ColdFusion makes it pretty simple, so let's take a look.

Let's first take a look at PDFs on the file system. This directory consists of the PDF files you want to merge. By default ColdFusion will merge all files in the folder. There are three things to consider when working with a folder:.

The code begins by simply creating two PDFs. These PDFs are stored to the file system in a subfolder named pdfs. The important line is here:. I simply specify a directory and in my case, a name variable to store the result in memory. Lastly I serve up the PDF with the cfcontent tag. If you run this you will notice that the PDF seems backwards. This makes sense if you remember the above notes. The default order is by time, descending, and PDF2 was written out first.

Now let's take it up a notch and introduce a new tag, cfpdfparam. The cfpdfparam tag is only used with merging PDFs. It lets you do all kinds of fun things. It gives you the power to provide more control over the order. It lets you specify a page range for each PDF. So for example, merge pages in pdf 1, pages in pdf 2, and pages in pdf 3. You can also supply passwords for individual PDFs that need them.

Pretty cool, eh? Here is a simple example:. This example is much like the first one. I create two PDFs with cfdocument. This time though I don't bother saving them to the file system. I then do the merge operation, but note the use of cfpdfparam. Now my order will work correctly because I explicitly specified the proper order.

I could have used filenames as well. And let me thank Adobe again for supporting relative paths! One final note - another option for merging PDFs is "keepBookmark". I'll be talking about bookmarks more in the next entry. Please let me know if you are enjoying this series. The last entry didn't get any comments so I want to make sure folks are still getting it.

You can even buy me a coffee! You can supply the order attribute to change this to name. You can change this by using the ascending attribute. The default value is no. CFPDF will try to merge every file in a folder. Raymond Camden's Picture. About Raymond Camden Raymond is a developer advocate.

ColdFusion 8: Working with PDFs (Part 5)

This is just a minor note but a really powerful piece of information. Memory was at mb when the file started, memory was at when the file transfer completed. The file was meg, and the transfer took about 2 minutes. The memory graph never spiked, and never went over meg, though it did clearly do a garbage collection in the middle of the transfer and drop down to meg before rising gradually to again. Not to reiterate what he just said, but it looks like our assumptions were wrong - ColdFusion's CFContent tag is being smart about the way it reads in and streams file data to the client browser. Clearly, memory usage should not be a concern when it comes to the use of CFContent to stream secure files out of a document library. And, as I have been told before, tying up the thread to stream the file is not much of a concern either; I have no real evidence about the thread usage one or the other, so I just have to go with what I have been told.

Data output tags. You can specify this tag's attributes in an attributeCollection attribute whose value is a structure. Specify the structure name in the attributeCollection attribute and use the tag's attribute names as structure keys. Now, ColdFusion attempts to get the content type from the file.
