img-window(n) Img img-window(n)______________________________________________________________________________NAMEimg-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 win‐
dow.
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 automati‐
cally. 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.
[2] The format name window is recognized by the option -format.
