# Reqirements: Perl5, Ghostscript
# History:
#   2002/10/30 v1.0: First release.
#   2002/10/30 v1.1: Option --hires added.
#   2002/11/04 v1.2: "nul" instead of "/dev/null" for windows.
#   2002/11/23 v1.3: Use of File::Spec module's "devnull" call.
#   2002/11/29 v1.4: Option --papersize added.
#   2004/06/24 v1.5: Clear map file entries so that pdfTeX
#                    does not touch the fonts.

${title}Syntax:   \L$program\E [options] <input[.pdf]> [output file]
Function: Margins are calculated and removed for each page in the file.
Options:                                                    (defaults:)
  --help              print usage
  --(no)verbose       verbose printing                      ($bool[$::opt_verbose])
  --(no)debug         debug informations                    ($bool[$::opt_debug])
  --gscmd <name>      call of ghostscript                   ($::opt_gscmd)
  --pdftexcmd <name>  call of pdfTeX                        ($::opt_pdftexcmd)
  --pdfinfocmd <name> call of pdfinfo			    ($::opt_pdfinfocmd)
  --margins "<left> <top> <right> <bottom>"                 ($::opt_margins)
                      add extra margins, unit is bp. If only one number is
                      given, then it is used for all margins, in the case
                      of two numbers they are also used for right and bottom.
  --(no)clip          clipping support, if margins are set, ignored when
		      in absolute mode  ($bool[$::opt_clip])
  --(no)hires         using `%%HiResBoundingBox'            ($bool[$::opt_hires])
                      instead of `%%BoundingBox'
  --papersize <foo>   parameter for gs's -sPAPERSIZE=<foo>,
                      use only with older gs versions <7.32 ($::opt_papersize)
  --unit <unitname>   set margins unit (pt, in, mm, cm, P) ($::opt_unit)
  --mode <standard | absolute | auto | auto2> ($::opt_mode)
		      pick crop mode :

		      standard - orginal pdfcrop working mode - each page is cropped
		      to individual size based od bbox size and taking margins into
		      account

		      absolute - clip size will be calculated based on pagesize returned
		      from pdfinfo command, not bbox. Thus, all pages will have
		      same size. Margin option set cropping box (i. e. how much to crop
                      from each side

  	              auto - clip size will be calculated based on maximum bbox dimensions
		      from all pages. Thus, all pages will have same size, 
		      minimum required to fit all document elements 

		      auto2 - clip size will be calculated based on maximum bbox size
		      from all pages. Thus, all pages will have same size, 
		      minimum required to fit all document elements This differs from auto mode
			- while in auto mode output size is stretched to fit all page elements,
  		 	in auto2 mode, bbox is first moved to fit actual elements and then
		      resized, if required. This should result in bit smaller pages than
		      auto mode.
	
  --exclude "<page1> <page2> ..." 
		      indicates which pages to exclude from calculations in Auto mode. 
		      You can put several page numbers here and as well as words "auto"
		      or "fullauto".
		      Auto causes pdfclip to stastitically choose pages
		      to exclude and ask for confirmation for each, wile fullauto means
		      to confirm all.
  --sens <sensitivity>
		      Sensitivity of auto exclusion. Default value is 3. Lower values
		      exclude more pages larger - less

  --align <lt | lb | rt | rb > ($::opt_align)
		      Used only in auto2 mode, decides to which page corner align page contents. 
		      l - left, t - top , r - rigth, b - bottom
Examples:
  \L$program\E --margins 10 input.pdf output.pdf
  \L$program\E --margins '5 10 5 20' --clip input.pdf output.pdf
  \L$program\E --mode auto input.pdf output.pdf
  \L$program\E --mode auto --exclude fullauto input.pdf output.pdf
