Bagi siapa pun yang ingin mengambil 1 atau 2 pg pdf dan mengubahnya menjadi pdf dengan 2 salinan yang berdampingan dalam tampilan lanskap ( bagus untuk mencetak brosur ), lakukan:
Ubah input pdf 1 atau 2 pg menjadi output yang berisi duplikat halaman-halaman tersebut (1-pg pdf -> 2-pg pdf, 2-pg pdf -> 4-pg pdf, dll):
pdfunite in.pdf in.pdf out.pdf
Gabungkan pdf duplikat-salinan itu menjadi pdf 2-halaman-per-sisi-dalam-lanskap-tampilan, untuk mencetak brosur misalnya:
pdfnup out.pdf
Atau semua dalam satu baris:
pdfunite in.pdf in.pdf out.pdf && pdfnup out.pdf
Perhatikan bahwa out.pdfadalah masukan untuk pdfnup. File keluaran yang dihasilkan pdfnupakan disebut " out-nup.pdf ".
Juga, perhatikan output dari pdfnupperintah dan Anda akan melihat bentuk verbose dari perintah itu benar-benar berjalan, yang memberi Anda beberapa wawasan tentang opsi yang dapat Anda berikan. Rupanya pdfnupmenggunakan di pdfjambawah tenda:
pdfjam: Panggilan efektif untuk menjalankan pdfjam ini:
/usr/bin/pdfjam --suffix nup --nup '2x1' --landscape -- out.pdf -
Contoh:
PDF asli (1 pg biasa dalam tampilan Potret), " in.pdf ":
Final PDF (2 pgs berdampingan dalam tampilan Lansekap), " out-nup.pdf ":
- sekarang dapat dipotong menjadi dua bagian tengah untuk dibagikan sebagai selebaran
Fungsi Bash sederhana: make_flyer
Salin dan tempel fungsi bash ini ke bagian bawah file "~ / .bashrc" Anda untuk mendapatkan akses ke perintah sederhana dan mudah digunakan 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.
