Merge 2 PDF (Letterhead)

The Aloaha PDF SDK function merge_A_and_B merges 2 PDF files together. This important function can be used to apply letterheads to existing PDF documents.

Please have a look at the sample below:

dim pdf
dim filea           'inputfile
dim fileb           'page 1 of filea will be rendered over fileb
dim outputfile   'filea and outputfile could be the same

set pdf=createobject("aloahapdf.edit")

          'if last boolean is set to false only first page of filea will be rendered
          Call pdf.merge_A_and_B(cstr(filea), cstr(fileb), cstr(outputfile, False)

set pdf=nothing


The registry key HKLM\Software\Aloaha\pdf\LayeredPDFLetterhead defines if only one or several PDF Layers are used. The key HKLM\Software\Aloaha\pdf\PDFLetterHeadLayer defines the PDF Layer to be used for the Letterhead.
