MergeEx

The MergeEx method merges two PDF documents by combining the contents of every page of the first document with a page from the second document.

ActiveX

Syntax:

Parameters:

Return Value

Option	Name	Description
0	No Repeat	The source file merges without repetition.
1	Repeat Option 1	The contents of the current document are repeated on all pages.
2	Above	The contents of the current document are above the document specified.
4	Layered	Place each merged document on a separate layer. The layer name will be the same as the document title.
64	Repeat Option 2	The first N-1 pages of an N page document will be merged over the right-side document's pages, the Nth (last page of left-side document) will repeat over all remaining pages of right-side document.

The return value is True if the file was merged. If the MergeEx method fails, an exception is raised and there is no return value.

Remarks

MergeEx is used when the second file was opened using the CDIntf.Document class.

If the documents do not have the same number of pages, say doc1 has N1 pages and doc2 has N2 pages where N1 < N2, then the developer can choose to:

E.g.: if doc1 contains the company’s letterhead in PDF format as one page, doc2 is a two page invoice in PDF format generated with the accounting package, one can call:

The two Repeat Options are mutually exclusive. If both are specified, the Repeat Option 1 only will be used.

Example

Visual Basic .Net
C#
Java
PowerShell
VBScript
