Options

• -output filename: Filename of the output file. (Default: a.out.pdf)
• -columns nh, -lines n_v: Output page layout. Each pages in input pdf files will be arranged into n_h columns × n_v lines in a output page. (Default: n_h=2 × n_v=1 ("2up") )
• -page-order option: Order of the sub-Page layout.
  • left2right: Top line will be filled with sub-pages from left to right at first. Then, next lower lines will be filled with sub-pages.
  • left2bottom: Most left columns will be filled with sub-pages from top to bottom at first. Then, next right columns will be filled with sub-pages.
  • left2top: Most left columns will be filled with sub-pages from bottom to to at first. Then, next right columns will be filled with sub-pages.
  • right2left: Top line will be filled with sub-pages from right to left at first. Then, next lower lines will be filled with sub-pages.
  • right2bottom: Most right columns will be filled with sub-pages from top to bottom at first. Then, next left columns will be filled with sub-pages.
  • right2top: Most right columns will be filled with sub-pages from bottom to top at first. Then, next left columns will be filled with sub-pages.
• -rotation option: Sub-Page orientation
  • none: Each sub-pages will be located with original orientation. (Default)
  • flip: Each sub-pages will be rotated by 180-deg.
  • right: Each sub-pages will be rotated 90-deg counterclockwise.
  • left: Each sub-pages will be rotated 90-deg clockwise.
  • auto: If the first sub-page is in an output pageportrait (landscape), only the landscape (portrait) subpages in a same output page will be rotated by 90-deg counterclockwise.
  • rauto:　If the first sub-page in an output page is portrait (landscape), only the landscape (portrait) subpages in a same output page will be rotated by 90-deg clockwise.
• -valign opttion: Adjustment of vertical position of sub-pages.
  • none,bottom: Align the bottom of sub-pages for each lines (Default)
  • center: Align the vertical center of sub-pages for each lines (Default)
  • top: Align the top of sub-pages for each lines (Default)
  • resize: Shrink the sub-page size with its height become same as that for the first sub-page in a same output page. If this option is specified with -algin resize or -algin fit, much smaller scale factor may be applied, but the vertical sub-page spacing is same as the height of the first sub-page in the page.
  • fit: Shrink the sub-page size with its height become same as that for the first sub-page in a same output page. If this option is specified with -algin resize or -algin fit, much smaller scale factor may be applied, and the vertical sub-page spacing may also become less than the height of the first sub-page in the page.
• -align opttion: Adjustment of horizontal position of sub-pages.
  • none,left: Align the right of sub-pages for each columns (Default)
  • center: Align the horizontal center of sub-pages for each columns
  • right: Align the left of sub-pages for each columns
  • resize: Shrink the sub-page size with its width become same as that for the first sub-page in a same output page. If this option is specified with -valgin resize or -valgin fit, much smaller scale factor may be applied, but the horizontal sub-page spacing is same as the width of the first sub-page in the page.
  • fit: Shrink the sub-page size with its width become same as that for the first sub-page in a same output page. If this option is specified with -valgin resize or -valgin fit, much smaller scale factor may be applied, and the horizontal sub-page spacing may also become less than the width of the first sub-page in the page.
• -metainfo options: Meta-data (document info) of output PDF file.
