PDF ファイルの一部だけを取り出す方法

PDF ファイルの一部だけを取り出すには、 pdfjam や pdfcrop というコマン ドを利用すればよいようでござる。 pkgsrc では、 pdfjam は print/pdfjam を、 pdfcrop は graphics/tex-pdfcrop をインストールすることで利用でき るようになるようでござる。

pdfjam は以下のように使えばよいようでござる。

trim オプションに与える四つの数字は切り取る領域の範囲で、それぞれ左、 下、右、上から切り捨てる幅の長さを与えるようでござる。 


     --KEY VALUE
                  Specify options to '\includepdfmerge', in the LaTeX
                  'pdfpages' package.  Here KEY is the name of any of the
                  many options for '\includepdfmerge', and VALUE is a
                  corresponding value.  Examples are
                      --nup 2x1     (for 2-up side-by-side imposition)
                      --scale 0.7   (to scale all input pages to 70% size)
                      --offset '1cm 0.5cm'
                                    (to offset all pages -- note the quotes!)
                      --frame true  (to put a frame round each input page)
                      --trim '1cm 2cm 1cm 2cm' --clip true
                                    (to trim those amounts from left, bottom,
                                     right and top, respectively, of input 
                                     pages) 
                  etc., etc.  For more information see the manual for
                  the 'pdfpages' package, at
                  http://www.ctan.org/tex-archive/macros/latex/contrib/pdfpages
* '--' can be used to signal that there are no more options to come.
