■ Merge individual PDF files, and pages within those files, explicitly, even if the source files
are stored in different locations.
■ Merge the contents of a PDF variable generated by the cfdocument tag or a cfpdf tag
To merge the contents of a directory, use the merge action and specify the directory where the
source PDF files are located, as the following example shows:
By default, ColdFusion merges the source files in descending order by timestamp. You can
control the order in which the PDF files are added to the book by setting the order and
ascending attributes. The following code merges the files in ascending order according to the
timestamp on the files:
By default, ColdFusion continues the merge process even if it encounters a file that is not a
valid PDF document in the specified directory. To override this setting, set the stopOnError
attribute to yes, as the following example shows:
You can merge a comma-separated list of PDF files. To do this, you must specify the absolute
pathname for each file, as the following example shows:
For more control over which files are added to the merged document, use the cfpdfparam tag
with the cfpdf tag. The cfpdfparam tag merges documents or pages from documents located
in different directories into a single output file. When you use the cfpdfparam tag, the PDF
files are added to the output file in the order they appear in the code. In the following
example, the cover, title, and copyright pages are followed by the first five pages of the
introduction, then all of the pages in Chapter 1, and then the first page followed by pages 80–
95 in Chapter 2:
