Merges two or more PDFs into a single PDF by using the external
application ghostscript.
+Normally the function returns the contents of the resulting PDF.
+if The parameter C<out_path> is set the resulting PDF is in this file
+and the return value is 1 if it successful or 0 if not.
+
The recognized parameters are:
=over 2
=item * C<file_names> – mandatory array reference containing the file
names to merge.
+=item * C<inp_content> – optional, contents of first file to merge with C<file_names>.
+
+=item * C<out_path> – optional, returns not the merged contents but wrote him into this file
+
=back
Note that this function relies on the presence of the external
projects / kivitendo-erp.git / blobdiff
