すれ違ったページ順に2つのPDFファイルをマージする方法は？

pdftkにはページを構成するshuffleコマンドがあります。

pdftk A=odd.pdf B=even.pdf shuffle A B output collated.pdf

pdfseparateとpdfuniteコマンドを参照してくださいpoppler-utils。 1 つ目は各文書のページを別々のファイルに分割し、2 番目は必要な順序で新しい文書にマージします。

また、スキャナーはとにかくラスターイメージを提供するので（あなたのスキャナーはそれをPDFファイルにリンクすることができます）、イメージ（png、tiff ...）を出力するように設定してからPDFにリンクすることができます。イメージマジシャン自身。

すぐにbash撮ってくださいpdfjam:

入力パラメータ配列を作成します。

for k in $(seq 1 ${N_PAGES}); do
    PAGES+=(odd.pdf);
    PAGES+=($k);
    PAGES+=(even.pdf);
    PAGES+=($k);
done

これにより、次の項目の入力リストとして使用できますpdfjoin。

 pdfjoin ${PAGES[@]} --outfile shuffled.pdf

私はこれを行うbashスクリプトを見つけました。偶数ページを逆順にスキャンしたとしますが、これを変更して行-rの内容を削除できますevenpages=($(ls "$evenbase-$key-"* | sort -r))（46行）。

# This script interleaves pages from two distinct PDF files and produces an
# output PDF file. The odd pages are taken from a first PDF file and the even
# pages are taken from a second PDF file passed respectively as first and second
# argument.
# The first two pages of the output file are the first page of the
# odd pages PDF file and the *last* page of the even pages PDF file. The two
# following pages are the second page of the odd pages PDF file and the
# second to last page of the even pages PDF file and so on.
#
# This is useful if you have two-sided documents scanned each side on a
# different file as it can happen when using a one-sided Automatic Document
# Feeder (ADF)
#
# It does a similar job to :
