NAME

img-window - Img, Tk Windows (window)

SYNOPSIS

package require Tk 


package require img::window ?1.3?


image create photo ?name? ?options?





 


DESCRIPTION

The package img::window 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::window.


Like all packages of Img it does not provide new commands, but
  extends the existing Tk command image. More specifically
  img::window extends Tk's photo image type.


The name of the new format handler is window.


This handler does not provide additional configuration options. This handler is
  special. Instead of reading or writing image data from a file or string it
  allows the embedding of a Tk widget into the photo image. In other words, it
  takes a snapshot of the contents of a Tk window.


All of the above means that in a call like


  
image create photo ?name? ?options?

  





  
[1]

  
Image data in window format (option -data) is detected
      automatically. Image data is considered to be in the window format
      if the value given to option -data is the name of an existing Tk
      window.
    

    Note that the standard option -file is not supported by this
    handler.

The format name window is recognized by the option
    -format.
