NAME


img-ps - Img, Adobe PostScript Format (ps)






SYNOPSIS


package require Tk 


package require img::ps ?1.4?


image create photo ?name?
  ?options?










DESCRIPTION


package require img::ps.


Like all packages of Img it does not provide new
    commands, but extends the existing Tk command image so that it
    supports files containing raster images in the Adobe PostScript Format (ps).
    More specifically img::ps extends Tk's photo image
    type.


The name of the new format handler is ps. This handler
    provides new additional configuration options. See section PostScript
    OPTIONS for more detailed explanations.


Note that this package provides a pdf handler too, i.e. a
    handler for the Adobe Portable Document Format. That handler accepts the
    same options as the ps handler.


The package delegates the actual conversion of data in PostScript
    and PDF format into a raster image to the ghostscript application. It
    therefore depends upon the presence of said application and is
    non-functional if ghostscript is not present.


All of the above means that in a call like



  

  





  
[1]

  
Image data in ps and PDF format (options -data and -file) is
      detected automatically.

  
[2]

  
The format names ps and pdf are recognized by the option
      -format. In addition the value for the option is treated as list
      and may contain any of the special options listed in section PostScript
      OPTIONS.








NOTE


This format handler must be loaded explicitly with package
    require img::ps.






POSTSCRIPT OPTIONS


The handler is not able to write images in PostScript or
    PDF. The handler provides the following options:



  

  
This option is for reading from PostScript/PDF data containing more than
      one page. When specified it will read the n'th page in the data.
      The first page is at index 0 and will be read by default, i.e. when
      the option is not specified.
    
Note: This option is not yet implemented.

  

  

  
Multiply image size by the given scale factors. If Y is missing,
      the default is the same as X. X and Y are allowed to
      be in floating point format, but they are rounded to the nearest
      practically possible value. For postscript this means the zoom factors
      should be multiples of 1/72.








REQUIREMENTS


The code provided by Img does not perform the interpretation and
    rasterizing of the input by itself but delegates this to the gs
    application. This is the GhostScript implementation of PostScript (and
  PDF).


If gs is not installed this format handler cannot be
  used.
