About

ospi

For installation instructions, see the INSTALL file.

ospi is a PDF imposer based on PoDoFo. It produces PDF files from PDF files, re-arranging pages according to an imposition plan. ospi is a Free software released under GPLv3

Invocation

ospi takes all its parameters in the form of key=value pairs. The only required key is "plan_file" which indicates to the program which imposition file to process. An optional key goes for "plan_type" to instruct the program on which plan reader it should call to process the plan file. If this key is missing, it will try to guess based on the extension of the plan filename. All other parameters are specific to each plan reader.

ospi processes imposition plan files in:

  • plain text format (simple)
  • JSON format (json).

Simple

The simple format is primarily intended to test ospi.

/skip/

JSON

The json format has been developed by CatPrint.com to integrate their workflow. The descrition of the format is as follows:

{
"plan": [{
  "page_width": decimal_ps_points,
  "page_height": decimal_ps_points,
  "slots": [{
    "width":  decimal_ps_points, /*width, height default to source page dimensions*/
    "height": decimal_ps_points,
    "left":   decimal_ps_points, 
    "top":    decimal_ps_points, 
    "file":   "local file location",
    "page":   1, /* page of PDF, if absent defaults to 1 (in "natural counting")*/
    "remote_file": { 
      "url": "remote file location", 
      "type": "‘pdf’ | ‘jpg’ | ‘html’"
    },
    "crop_width":  decimal_ps_points,
    "crop_height": decimal_ps_points,
    "crop_left":   decimal_ps_points,
    "crop_top":    decimal_ps_points,
    "rotation":    "0 | 1 | 2 | 3"
    }, ...
    /* repeat for each slot */
    ]
  }, ...
  /* repeat for each page */
  ]
}

Example:

$ ospi plan_file=plan8up.json plan_type=json output_file_name=imposed_doc.pdf
