NAME


img-ico - Img, Windows Icon Format (ico)






SYNOPSIS


package require Tk 


package require img::ico ?1.4?


image create photo ?name?

DESCRIPTION


The package img::ico 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::ico.


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 Windows Icon Format (ico).
    More specifically img::ico extends Tk's photo image
    type.


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


All of the above means that in a call like

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

  
[2]

      addition the value for the option is treated as list and may contain any
      of the special options listed in section ICO OPTIONS.
