Re Advanced PDF Tools Command Line:
The description says that one may merge pdf files. I do not see a merge command.
The closest i see is:
Insert pages to PDF file
-*
pdftools -i "C:\input.pdf" -o "C:\output.pdf" "-*" "2|0|d:\pdf1.pdf/1,2-4,9|d:\pdf2.pdf/1,3"
So, say I want to combined:
1.pdf, 2. pdf, 3.pdf, and 4.pdf into output.pdf
Is this the command?
pdftools -i "C:\1.pdf" -o "C:\output.pdf" "-*" "2.pdf, 3. pdf, 4.pdf"
Thanks
==========================
