The MergeFiles function merges two PDF documents by combining the contents of every page of the first document with a page from the second document.
BOOL MergeFiles(LPCSTR file1, LPCSTR file2, LPCSTR file3, long Options)
file1
Full path of the first file containing the watermark.
file2
Full path of the second file to which file1 should be merged.
file3
Full path of the destination or output file.
Options
Options for merging files.

Description |
|---|---|---|
Repeat first pages |
1 |
The first pages of the second document are repeated in the first document. |
Second document above first |
2 |
The contents of the second document are printed above the contents of the first document. |
The return value is True if the files were merged, False otherwise.
This function is not guaranteed to process files created from PDF generation tools other than the Amyuni PDF Converter, or Amyuni PDF Creator. It will however work with files coming from most applications.
If the documents do not have the same number of pages, say file1 has N1 pages and file2 has N2 pages where N1 < N2, then the developer can choose to:
Either merge file1 with the N1 pages of file2 and keep the remaining N2-N1 pages of file2 unchanged, in this case the Repeat option should be set to 0.
Or merge the first block of N1 pages of file2 with the N1 pages of file1, merge the second block of N1 pages of file1 with the N1 pages of file1 and so on, in this case Repeat should be set to 1.
