img-tiff - Img, Tagged Image File Format (tiff)








package require Tk 


package require img::tiff ?1.4?


image create photo ?name?
  ?options?












The package img::tiff is a sub-package of Img. It
    can be loaded as a part of the complete Img support, via package require
    Img, or on its own, via package require img::tiff.


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 Tagged Image File Format
    (tiff). More specifically img::tiff extends Tk's photo
    image type.


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


All of the above means that in a call like



  

  





  
[1]

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

  
[2]

  
The format name tiff is 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 TIFF OPTIONS.










The handler provides three options, one for reading from a TIFF
    image, the other two influencing the writing of such.



  

  
This option is for reading from TIFF files containing more than one image
      (multi-page TIFF. When specified it will read the n'th image
      in the data. The first image is at index 0 and will be read by
      default, i.e. when the option is not specified.

  

  
This option specifies the type of compression to use when writing TIFF
      data. It has to be one of none, jpeg, packbits, or
      deflate. The default is none.

  

  
This option specifies the byteorder to use when writing TIFF data. It has
      to be one of bigendian, littleendian, network,
      smallendian, or the empty string. The default is the empty string.
    
The values bigendian and network are aliases of
        each other, as are littleendian and smallendian.
