How to concatenate multiple pdf as one, each input pdf starting on an even page?
问题 DUPLICATE OF How can I merge PDF files (or PS if not possible) such that every file will begin in a odd page? I have a serie of documents, each one with an unpredictable number of pages. Say : a.pdf (1 page : A1) b.pdf (3 pages : B1, B2, B3) c.pdf (4 pages : C1, C2, C3, C4) I want to merge these input files into one out.pdf, that I'll print double-side. Every first page of the input files must be on a front (right) page. This means the expected result would be |A1 --|B1 B2|B3 --|C1 C2|C3 C4|
