如何合并 2 个具有交错页面顺序的 PDF 文件？

我有一份双面打印的多页文档，需要使用线性批量扫描仪进行扫描。因此，结果我得到 2 个 PDF 文件：一个包含所有奇数页，第二个包含所有偶数页。我需要以自然的方式合并它们：

1. <- 1.1. (odd.pdf page 1 to result.pdf page 1)
2. <- 2.1. (even.pdf page 1 to result.pdf page 2)
3. <- 1.2. (odd.pdf page 2 to result.pdf page 3)
4. <- 2.2. (even.pdf page 2 to result.pdf page 4)

ETC。

答案1

pdftk 有一个整理页面的 shuffle 命令：

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

答案2

请参阅中的pdfseparate和pdfunite命令poppler-utils。第一个将每个文档的页面分成单独的文件，第二个将它们按照您想要的顺序合并到新文档中。

另请注意，由于扫描仪无论如何都会为您提供光栅图像（像您一样的扫描仪可以将其连接成 PDF 文件），也许您可​​以将其配置为输出图像（png、tiff ...），然后自己将其连接成 PDF图像魔术师。

答案3

只需bash快速拍摄即可pdfjam:

构建输入参数数组：

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

这应该允许您将其用作以下内容的输入列表pdfjoin：

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

答案4

我遇到了这个 bash 脚本这样做，它假设您以相反的顺序扫描了偶数页，但是您可以更改此设置，删除-r行中的内容evenpages=($(ls "$evenbase-$key-"* | sort -r))（这是第 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 :
