ambil 4 halaman pertama dari setiap 8 halaman

 

File PDF Anda berisi 288 halaman, seharusnya berisi 34 siswa × 4 halaman = 136 halaman. Tapi nyatanya ada data berulang setiap 4 halaman (seperti halaman 1–4 dan 5–8 milik siswa yang sama). Jadi, siswa yang sama muncul dua kali, sehingga total jadi 288 halaman.

Tujuan:

Ambil hanya 4 halaman pertama dari setiap 8 halaman, total untuk 34 siswa aktif.

 

✅ Solusi:

Cara otomatis dengan pdfcpu (di Ubuntu):

Jika Anda sudah punya pdfcpu, gunakan perintah ini untuk mengambil setiap 8 halaman, dan dari itu ekstrak hanya 4 halaman pertama:

langkah 1 

pdfcpu split rapor_lengkap.pdf bagian 8

 

langkah 2 

setelah itu 

mkdir hasil_akhir
for file in bagian/*.pdf; do
  filename=$(basename "$file")
  pdfcpu trim -pages 1-4 "$file" hasil_akhir/"$filename"
done

Setelah itu, untuk menggabungkan semua hasil menjadi satu file PDF:

 $ pdfcpu merge rapor_final.pdf hasil_akhir/*.pdf
writing rapor_final.pdf...
