Per chiunque desideri prendere 1 o 2 pg pdf e trasformarlo in un pdf con 2 copie affiancate di quella vista orizzontale ( ideale per stampare volantini ), fare:
Trasforma l'input 1 o 2 pg pdf in un output che contiene una copia duplicata di quelle pagine (1-pg pdf -> 2-pg pdf, 2-pg pdf -> 4-pg pdf, ecc.):
pdfunite in.pdf in.pdf out.pdf
Combina quel PDF con copia duplicata in un pdf di 2 pagine per lato in modalità orizzontale, ad esempio per stampare volantini:
pdfnup out.pdf
O tutto su una sola riga:
pdfunite in.pdf in.pdf out.pdf && pdfnup out.pdf
Si noti che out.pdfè l' input per pdfnup. Il file di output risultante da pdfnupverrà chiamato " out-nup.pdf ".
Inoltre, guarda l'output del pdfnupcomando e vedrai la forma dettagliata del comando che sta effettivamente eseguendo, il che ti dà un'idea delle opzioni che puoi passare in esso. Apparentemente pdfnupusa pdfjamsotto il cofano:
pdfjam: chiamata efficace per questa corsa di pdfjam:
/usr/bin/pdfjam --suffix nup --nup '2x1' --landscape -- out.pdf -
Esempio:
PDF originale (1 pagina normale in vista verticale ), " in.pdf ":
PDF finale (2 pg affiancati in vista orizzontale ), " out-nup.pdf ":
- ora può essere tagliato a metà in mezzo per passare come volantini
Funzione Bash semplice: make_flyer
Copia e incolla questa funzione bash nella parte inferiore del file "~ / .bashrc" per ottenere l'accesso a un comando semplice e facile da usare make flyer:
# Description: outputs a landscape-oriented flyer pdf ("my/pdf/input--flyer.pdf") for each 1 or more pg input pdf ("my/pdf/input.pdf")
# - 1-pg input PDFs are converted to a 1-sided landscape, printable flyer that you cut down the center to make
# 2 flyers
# - 2-pg input PDFs are converted to a 2-sided landscape, printable flyer (flip on short edge when printing
# double-sided), and also cut down the middle to make 2 flyers
# - **3+ pg input PDFs**: using `pdfnup` directly in this case would make more sense, since this function will
# otherwise unneccessarily create 2 copies
# - 3 and 4-pg input PDFs are converted to a single piece of paper, double-sided, flipped on short edge, x 2 copies.
# No cutting is necessary
# - 5+ pg input PDFs simply require half as much paper to print is all since you get 2 pages per side of paper;
# they do NOT print like booklets, but rather just as a landscape-printed, flipped-on-short-edge bundle of pages
# (like a deck of slides). You get *2 copies* per print though, so just print half the pages.
