       package require img::ico  ?1.4?

DESCRIPTION

       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.

       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.

       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 create photo ?name? ?options?

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

       [2]    The format name ico 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 ICO OPTIONS.
